Technical Requirements for LPFM Station Operation
[Getting started][Transmission
facilities][Broadcast studio]
While the FCC hopes that LPFM stations will have relatively simple operations,
nonetheless the Commission is requiring LPFM stations to meet most of
the same legal and technical requirements that all educational, noncommercial
FM stations must meet. Most of these operating requirements are simple
and inexpensive, but they include having to participate in the EAS (Emergency
Alert System) by installing special equipment, and keeping such records
and logs as the FCC might require to ensure that your transmitter is operating
properly without causing interference. [For detailed up-to-date operating
requirements of non-commercial public radio stations, contact the National
Federation of Community Broadcasters.]
Getting Started
There are three main technical elements that are needed to operate a
radio station:
A physical place to hang an FM antenna.
A place to install a transmitter.
A location for your broadcast studio.
To apply for an LPFM license, you MUST have a location to install your
antenna and transmitter. You do not need a studio location to fill in
the application. But eventually you will need a studio site before you
go on the air.
Transmission Facilities
The antenna and the transmitter are your broadcast transmitting elements.
This is where your signal originates and goes out into the airwaves. These
two pieces of equipment are usually (but not always) installed in proximity
to each other. For LPFM, the FCC requires that your transmitter and antenna
be located within 10 miles of where your organization functions.
An FM antenna is similar to a television antenna that you might
put on a roof to improve TV reception. It can be installed on a mast or
pole secured to the roof of a building, on a freestanding tower, or on
some other structure that elevates it above the ground. This can be anywhere
from 100 to 1000 feet or higher, if it is on a hill or mountain.
The signal reaches the radiating elements of the antenna through
a special cable that is connected to the transmitter. The cable leaves
the transmitter and must be long enough to reach the antenna, feeding
the broadcast signal.
The transmitter is generally located in a closet or room on or near the
roof, somewhere else in the same building as the antenna, or in a shack
or building on the ground under the tower.
The antenna does not need its own power. It gets its power from
the transmission signal and is designed to be outside.
The transmitter needs electricity and must be inside, protected from
the weather.
Both your antenna and your transmitter must be ětunedî to the frequency
you are assigned by the FCC, so that the signal is broadcast on the correct
channel and only that channel. When you purchase your transmitter, you
will tell the manufacturer your frequency and it will arrive pre-tuned
or with instructions on how to tune it. LPFM antennas are broadband, and
will be able to transmit from any frequency you are assigned. The manufacturer
will tell you if it needs to be pre-tuned.
Broadcast Studio
The programs you broadcast originate from a control room, also called
a broadcast studio. This is the place where the microphones, CD players,
cassette machines, and other equipment is located so people can produce
live and recorded radio programs. Most commercial and many non-commercial
public radio stations have several control rooms and studios, where they
can record, edit, mix and broadcast programs all at the same time. But
a radio studio does not need to be either expensive or complicated to
sound good and be easy to use.
You do not need an FCC license or any permissions to build and
run a radio production studio.
You do not need any kind of special room. The studio can be in
its own dedicated room, in a closet, or even in a corner of a room that
is used for other purposes. The main condition is that it be quiet enough
that the room noise does not overly distract from your radio broadcast,
or be too confusing to listeners.
Consumer quality equipment, such as CD players and cassette decks,
is adequate for most broadcast uses that you might have.
However, if you intend to learn or teach more advanced radio skills or
production techniques, or use some equipment very heavily, you might want
to invest in professional quality equipment which is more expensive but
designed for long-term durability.
To be heard on the radio, the programs that you originate in your studio
must travel to the transmitter in one way or another, by cable, or through
the air. Try to locate your studio as close to the transmitter as possible.
If you can, put the studios in a room nearby where the transmitter is
located. Then, connecting the equipment in your studio to your transmitter
might only need some cables.
If this is not possible, try to put your studio in the same building
as the transmitter. Often, studios are located on one floor of a building
and the transmitter is on the roof. The cable between them is run through
an elevator shaft, stairway, or other conduit that connects them.
You might have to locate your studio in another building or some other
place distant from the transmitter. In this instance, you will need
an STL Studio to Transmitter Link that will connect your program signal
to the transmitter in a reliable way.
There are several ways to set up an STL. One of the simplest is to get
a land line to provide a dedicated connection between your studio and
your transmitter. This is arranged through a phone service provider and
is similar to getting a regular dial-up phone line, but with better quality.
There are also other technical solutions, such as using a microwave link,
which requires a different kind of license from the FCC. The most cost-effective
and reliable method for your station will depend on the particular circumstance
and location of your facilities. [You will probably need an engineer to
help set up an STL.]
When these three elements - antenna, transmitter, and studio -- are hooked
up and turned on, you're on the air!!!
[Back to top]
How Much Will It Cost?
[the application][transmitter
and antenna][the studio][hiring
an engineer]
The technical costs for an LPFM station fall into three categories. In
each area, there are great variables, but you can use these as general
guidelines for costs.
Filling out
the Engineering Section of the Application
This is a relatively simple form to fill out, but it requires being able
to answer a number of specific technical questions required by the FCC.
This Guide will help you, but if you decide you cannot or do not want
do this on your own, we recommend that you hire a qualified broadcast
engineer to fill out this section of the application. Engineers will already
know the basic rules for geographic and frequency separation and have
the software on hand.
If you hire an engineer, he/she does not have to be local. They
do not have to visit you to fill out the application, as long as you provide
them with accurate information. The same technical rules apply across
the country, and they can run the computer program no matter where you
or they live. The costs we have been quoted for doing a frequency search
and filling out the application range from $250 - $1,000, but some engineers
are charging more. Most applications will probably cost around $500 to
complete. However, if your location has special conditions, or if you
need an exhibit or additional technical work, be prepared to pay more.
[See list of engineers.]
Transmitter and Antenna
By itself, an LPFM 100 transmitter will cost $3,500 - 6,500, and an
antenna will be $1,000 - 2,500. In addition, you will need coaxial
cable to connect them, some related monitoring equipment, and mounting
hardware. You might need a rack or other furniture for your transmitter,
and there are always unanticipated costs that are be required out of pocket.
All the equipment is produced by different manufacturers, and you can
purchase each piece individually. But equipment dealers will be putting
together transmission packages so you can order everything you need for
your transmitter and antenna at the same time. Based on such variables
as how far away your transmitter is from your antenna, and if you will
be broadcasting in monaural or stereo, you should expect a complete transmitter/antenna
package to cost $5,000 - $15,000. In most cases, buying a complete transmitter/antenna
package individualized for your location will be the most cost effective
way to get what you need.
Broadcast Studio Equipment
Unlike transmission facilities, there is huge variety in what you may
want to put in your studio. You can put together studios with consumer-grade
equipment that is purchased or donated, or standard professional quality
equipment that costs thousands of dollars.
It is likely that the most expensive single item you will need to
purchase is a mixing console, the piece of equipment that allows you
to mix microphones, CD players, and other music and recorded sources together
to go out over the air. A simple mixer can cost $350 - $2,500 new. Everything
else - microphones, CD and cassette players, headphones, etc.-- can range
wildly in price. If you are buying everything new, a modest package might
cost as little as $2,500. The price goes up from there. You will pay more
if you want all digital equipment, or plan to invest in a digital audio
workstation (DAW) for program production, which is a computer-based editing
system.
Here again, there will be a range of packages available from equipment
dealers who will want to sell you stuff you wonít really need. You can
hire an engineer to help you with this, but since most of it is regular
audio equipment, you can get help from a friendly local musician, sound
technician, audiophile or radio producer who knows audio recording and
would be pleased to advise you about putting together an appropriate complement
of studio equipment.
Hiring Broadcast Engineers
It is likely that at some point during your station construction,
you will need a broadcast engineer to assist you with an on-site installation
or facilities problem, such as transmitter testing or installing an STL.
You might want to make friends with one of the engineers who work for
the local commercial or public broadcast station. (Often engineers will
work for several stations at the same time.) Most of them will work on
an hourly basis for specific projects or emergencies, or on a contract
basis for a longer term project. Many of them might be willing to advise
you as a volunteer, or charge you only nominal fees.
You can also look for free or inexpensive help from other local technical
folks - amateur (ham) radio operators, musicians, producers, computer
technicians - people with technical expertise in related fields who can
provide the technical assistance you need. It isn't necessary that they
be an actual broadcast engineer to be skilled and knowledgeable about
equipment operations.
If you have an especially difficult technical problem, you may have
to bring in an outside "expert" from a professional engineering
firm. Be prepared to pay full non-commercial rates for such service,
but don't hesitate to negotiate.
"Turnkey" Operators
There are engineering firms that will offer to set up your station on
a "turnkey" basis. That is, for a single fee, they will do
all the work and handle EVERYTHING, from filling out and submitting the
application, to ordering and installing the transmitter and building the
whole studio. The costs for such services are generally high. Because
most LPFM stations will be technically simple to construct, hiring a turnkey
operator is probably not cost effective. However, if you want to consider
a turnkey operator, get several bids. Use the cost guidelines outlined
above for hardware, and add costs for labor and overhead to provide a
rough estimate of what the bid should cost. Be sure the bids are within
reasonable range.

All About Antennas
[location is key][Mounting
the antenna][Find your coordinates]
Finding a Good
Antenna Location is the Key
To win a new LPFM license, your application will have to meet both geographic
and frequency separation rules. Determining your success depends on where
your antenna will be geographically located.
The rules determining if a new station will be licensed are based
on the existing allocations the FCC uses to grant FM licenses. The
place on the dial is called the frequency (i.e. 93.5 FM) but the FCC also
calls it a Channel - each frequency has an equivalent channel number.
[The FCC has a chart with the parallel frequency and channel assignments
for the FM band.]
Because FM radio has been in operation for decades, the FCC has a well-established
set of rules governing frequency allocation (though this will radically
change with digital broadcasting.). With LPFM they are changing these
rules somewhat, but most of them still apply. The rules are based on protecting
the signals of existing stations, so that new stations can only go on
the air if they do not create any interference to stations already on
the air.
Basically, this means that the FCC draws an imaginary geographic circle
around every existing broadcast antenna, AND a protected space between
each FM frequency already assigned on the dial. Then they will try to
fit your station into the spaces between these separations. This is actually
a complex calculation that must take into account several interrelated
factors, including geographic location of the antenna, its height above
average terrain (because FM is line-of-sight, the higher an antenna, the
further its signal will reach) and the power of the signal (anywhere between
1-100 watts.)
Based on your proposed antenna location, the FCC will determine if
there is an available frequency. The new stations will be licensed
to operate anywhere they fit in the FM band, not only in the portion of
the band dedicated for noncommercial public radio use, and will be assigned
frequency allocations separated from existing stations by at least two
channels (first and second adjacent channels).
In a change from general practice, the new stations do NOT have to be
geographically separated from stations three channels away (third adjacent
channel.) For example, under the rules for existing full power stations,
if a station is operating on 93.5 FM, there can be no other station nearby
on 93.7 (first adjacent channel) 93.9 (second adjacent channel) or 94.1
(third adjacent channel.) According to the LPFM rules, a new station CAN
be licensed at 94.1 in the vicinity of the full power station. [This is
the rule change that the National Association of Broadcasters is trying
very hard to overturn.]
Where Should
You Put Your Antenna?
This is the most important part of Section V, because it will determine
if your proposed station can be awarded a frequency on the FM dial.
FM signals travel in line-of-sight, which means that the higher the
antenna is off the ground, the further the signal will travel. Any
physical obstruction in its way will stop the signal. FM antennas are
relatively small and light-weight, and can easily be attached to a wide
variety of supporting structures without any special reinforcement, such
as telephone poles, metal or wooden masts, water towers, elevated roof-top
structures, and existing towers. So be flexible in looking for a good
location. The FCC requires that your antenna be located within 10 miles
of your offices or campus.
Try to find the highest location possible for your antenna, such
as a spot above other buildings, on top of a hill, or some other place
where the signal will not readily hit a geographic feature or large solid
object. This might be a pole on the roof of your own building, the roof
of a higher building nearby, or some other tall structure in the vicinity.
You can also use an existing tower, either one on a roof top, or freestanding
on the ground.
LPFM antennas are small and lightweight, much like a TV antenna
that one puts on a roof to improve reception. They do not need a large
supporting structure or special reinforcement to hold them up, and they
will have little wind load. You can mount them on a mast or something
similar to get elevation.
If you do not own or control the location where you want to mount the
antenna, offer to put up a pole or small tower to elevate your antenna.
In some cases, you should be prepared to offer compensation or pay rent.
Along with the antenna site, you must secure a place nearby for your
transmitter. A 100 watt FM transmitter is not very large or heavy
- the box is roughly the size of a desk top computer. It can sit on a
shelf or table, or be installed in a rack. The location must have electricity,
but does not demand any special power requirements, and it must be inside
protected from the weather. Be prepared to pay the electric bill.
Finding your Antenna
Coordinates and Broadcast Channel
Determine Your Antenna Location - Once you know where you want
to put your antenna, you need two important pieces of information to fill
out the Tech Box. The FCC needs this information to determine if there
is an available frequency at your proposed location in relation to existing
stations in your area .
Geographic Coordinates of your antenna location - the FCC needs
the exact geographic coordinates in longitude and latitude of your antenna
location using North American Datum 27 (NAD 27) coordinates. If you are
going to use an existing tower, the owner or any other station at that
location will have the coordinates readily available. You can get the
information yourself. Height of your antenna - the FCC also needs the
exact height of your antenna above the ground and above sea level.Site
elevation and coordinates can be determined from a U.S.G.S.
7.5 minute topographical quadrangle map for your location. These are
maps prepared by the U.S. Geological Survey with precise topographical
features, including geographic coordinates and terrain elevations. The
maps are available for all areas of the country, including cities.
You can find these maps in many local libraries, at some map stores,
and at many camping goods stores that cater to hikers and orienteering.
The U.S.G.S. has an on-line list of all the locations where these maps
are sold. You can also order them directly for a few dollars. (http://mapping.usgs.gov/esic/usimage/dealers.html)
With the map, scale off your designated antenna location against the
latitude (horizontal) and longitude (vertical) reference marks on the
map. Coordinates must be determined to the nearest 1 second (degrees,
minutes, seconds = DDD MM SS). Once you have found your antenna coordinates
on this map, you can also determine the elevation by reading the elevation
lines closest to the marked location. Elevations are given in height above
mean sea level.
Once you have found your antenna coordinates on this map, you can also
determine the elevation by reading the elevation lines closest to the
marked location. Elevations are given in height above mean sea level.
It is possible to determine your exact geographic coordinates and elevation
above sea level using resources on-line. We have tested these sites out,
and they appear to be reliable and very useful! Geographic Coordinates
When you go to the FCC webpage, you will be asked to fill in the exact
location of your transmitter site. You may need to know these locations
in terms of longitude and latitude co-ordinates, the elevation above sea
level, and the height of the structure that the antenna will be built
upon.
It is possible to determine your exact geographic coordinates and elevation
above sea level using resources on-line. We have tested these sites out,
and they appear to be reliable and very useful!
We have not yet figured out whether these online resources are more or
less reliable than GPS units- your answer should be accurate to the nearest
second- and should be rounded off accordingly. If you have the opportunity,
you can try both and let us know if there is a discrepancy.
Geographic Coordinates
The website listed below will give you much more accurate geographic
coordinates than using the FCC site.
[http://www.geocode.com/scripts/eagle/eagle.pl?cmd=td_i]
(If that does not work, go to www.geocode.com Then go to "test drive
eagle geocoding" it will get you to the same place)
Enter the street address of your proposed site and it will give you the
coordinates in both decimal degrees and degrees/minutes/seconds, using
the NAD-27 standard required by the FCC. You need to copy down the degree,
minutes, and seconds of the co-ordinates. These can then be entered in
the FCC Channel Finder to determine if a frequency is available for this
location.
| Warning!
Do not use the FCC "co-ordinate locator. " That will tell you the
co-ordinates of the center of your town. This can be helpful for
checking the general radio environment of your area, but the availability
of a license at your location is a whole 'nother issue do not enter
those co-ordinates as if they are yours, or your application will
be rejected!
|
You can also determine your elevation using the following website:
[http://www.topozone.com]
Enter the same geographic coordinates, and this site will generate on
screen the correct U.S.G.S. topographical map for the location entered.
The maps on this site are very detailed graphically, so they may take
some time to download based on how fast your internet connection is.
At the top left of the map page are several scales - select 1:25,000,
which will give you the most resolution. At the top right, there are three
choices for size - select Large. What will then appear on your screen
will be the section of the map with your exact location, in the largest
magnification. The maps include major geographic features, such as mountains,
lakes, rivers, hills, etc. and major man-made features such as airports,
hospitals, cemeteries, parks, railroad lines, and significant buildings,
streets and highways. At this scale, most of these features should be
legible. Natural areas are green; developed areas are pink; water features
are blue; and new buildings or constructions are generally shown in purple.
If you look closely, you will also see a series of brown contour lines
that snake across the maps in irregular but roughly parallel patterns.
These lines follow the features of the terrain, and they indicate changes
in elevation every 10 feet. Where the elevation rises steeply they will
be close together, and where the ground is flatter, they will be spaced
farther apart. If you follow any one of these lines, at some point you
will see the line broken by a number that is a multiple of 10. This number
indicates the ground elevation, or height above mean sea level, for thatcontour.
With a good pair of eyes (or a large screen monitor) you should be able
to find your address and match it up with the nearest contour line. This
is the height of the ground above mean sea level. Add the height of your
building to this figure, and then add the height of any pole, tower or
other antenna support that will go on the roof. Add these figures together
to get the Antenna Location Site Elevation Above Mean Sea Level in feet.
Convert the feet into meters and the resulting figure is the correct entry
for Question 5 in Section V.
Navigating Through The FCC Application Process
[Using the channel finder][Converting
from frequency to channel number][Filling out the
form]
Using the
FCC Channel Finder
When you know your coordinates, you are ready to use the FCC Channel
Finder program. You can access it on-line at: http://www.fcc.gov/mmb/asd/lpfm/lpfm
channel_finder.html
The FCC has created the Channel Finder Program to determine whether the
NAD 27 coordinates of the proposed transmitter site meet the spacing requirements
adopted by the Commission. Using the program is NOT an application
for a LPFM station. Application Form 318 must be filed.
Finding out if there is an available channel for your location is
an important step.
According to the FCC, applications that do not meet the minimum separation
requirements of 47 CFR 73.807 and 73.825 with respect to licenses and
construction permits will be returned without an opportunity to submit
a corrective amendment. LPFM applications also must be spaced properly
with respect to FM station applications on file as of the release date
of the Public Notice announcing the dates for the LPFM application filing
window.
Running the Channel Finder will tell you if there is an available frequency
at your designated antenna location.
Employees of the Audio Services Division of the FCC or other Commission
staff cannot assist in finding your coordinates or running the program.
If you have any doubts or questions, consult a licensed engineer.
The FCC has made clear that inaccurate coordinates may result in dismissal
of the application by the staff. Geographic coordinates may be verified
by the staff or other interested parties.
The FCC also cautions applicants to consider if local zoning or other
land use restrictions might affect whether and how quickly an LPFM station
can be constructed upon FCC grant of a construction permit. However, zoning
or land use information or approval is not needed to file FCC Form 318
with the Commission for an LPFM construction permit.
Converting your
Frequency to a Channel Number
Each FM frequency has a corresponding channel, from 88.1 FM = Channel
201, to 107.9 FM = Channel 300. If you have successfully found a frequency,
then you must convert it to the correct channel number.
This is simple. The FCC has an easy channel conversion chart. (Or you
can do the math.) [http://www.fcc.gov/mmb/asd/bickel/chanfreq.html]
If you have found a frequency and determined its channel, you are ready
to fill out Section V.
Filling Out Engineering
Section V of FCC Application Form 318
Once you have found a frequency and determined its channel, you are ready
to fill out Section V. Be certain you have a copy of the "Instructions
for FCC Form 318" issued by the FCC. These instructions are dense
because they are written in the legal language of the FCC, but you will
need the Worksheets that are part of the document.
If you are uncertain about doing this correctly or you want help,
we recommend that you hire a professional broadcast engineer or other
experienced person fill out the application form on your behalf. They
know how to get proper FCC frequencies using geographic coordinates and
elevation above sea level. You will have to provide them with specific
information, such as street address, and the height of the building where
you want to put the antenna. They can figure out the rest.
The TECH BOX
Question 1. Class
Check the Box for LPFM 100
Question 2. Channel
If you have found a frequency using the FCC Channel Finder program, you
can convert the frequency to the correct channel using the FCC Channel
Conversion chart. Write/type the channel number on the line indicated.
Question 3. Antenna Coordinates
The proposed antenna site must be specified using North American Datum
27 (NAD 27) coordinates. You can determine these coordinates using a 7.5
minute series topographic map from the U.S. Geological Survey.
Fill in the boxes with the correct longitude and latitude based on the
location from the U.S.G.S. map. Coordinates must be to the nearest 1 second
(degrees, minutes, seconds = DDD MM SS).
Question 4. Antenna Structure Registration Number
Most towers taller than 62 meters (200 feet) and located near airports
are registered with the FAA.
If you are NOT using one of these towers, (because you are putting your
antenna on the roof of your building) check the box "Not Applicable"
If you are putting your antenna on one of these towers, check the box
"FAA Notification Filed with FAA." (You do not need to file
anything with the FAA - the tower owner is responsible.)
Question 5. Antenna Location Site Elevation Above Mean Sea Level
First, determine the ground elevation of your antenna location from the
same U.S.G.S. maps that helped you locate longitude and latitude. Then
add the height of your building, tower, or supporting structure to the
ground elevation indicated on the map.
The total will be the height of your antenna above Mean Sea Level. This
elevation must be recorded in meters, rounded to the nearest whole number.
Question 6. Overall Tower Height Above General Ground Level
This elevation is simply the height of your antenna above the ground.
It will be the total height of your building or tower, plus anything added
to support the antenna. It must be recorded in meters, rounded to the
nearest whole number.
Question 7. Height of Antenna Radiation Center Above Ground Level
This elevation will be the same or very close to the answer in Question
6 but may vary by a meter or two. A single LPFM antenna will have 1, 2,
or possibly more radiating elements (called "bays" or "antenna
array.") If there is more than one, they are mounted a few feet apart
on the support structure or tower. The center of radiation is the middle
of this array. If you are using a single bay antenna, your center of radiation
will be the same as your antenna height above the ground. (Most LPFM antennas
will have only one antenna bay.)
If you are going to use an antenna with 2 or more bays, the center of
radiation will be slightly lower than the top of the antenna. Determine
it by measuring the distance from the ground to the point half-way between
the top of the antenna and the bottom, based on how much space is between
each bay when it is mounted. (The antenna manufacturer will know the spacing
between bays.) It must be recorded in meters, rounded to the nearest whole
number. [See diagrams.]
Question 8. Power and Height Limitations
Check the "Yes" box. This acknowledges that the FCC will determine
the authorization for your operating parameters, including power and height
(i.e. based on the height of your antenna, you may be authorized to operate
at a power less than 100 watts.)
Question 9.
Interference -- You must answer "yes".
Short-spaced stations - answer "N/A"
Question 10. TV Channel 6 Interference (Channel 201-220)
Because of a quirky technical condition on the television spectrum, there
are special technical restrictions on FM radio frequencies in places near
a Channel 6 TV station. If there is NO Channel 6 TV station within 60
miles of your proposed antenna location, answer "N/A" If there
is a Channel 6 television station within 60 miles, AND the Channel Finder
has given you an allocation higher than Channel 220, answer "Yes."
If there is a Channel 6 TV station within 60 miles, AND the Channel Finder
has given you an allocation between 201 - 220, you will need an engineer
to assist you in preparing an exhibit to meet any necessary restrictions.
Question 11. National Environmental Policy Act
Over time, broadcast stations have become subject to a range of urban
and rural environmental regulations that have an impact on both personal
health and environmental protection. This question is intended to ensure
that all applicants certify that their proposed station will have no significant
impact on the quality of the human environment. The FCC has provided a
worksheet as part of its instructions that must be submitted along with
the application.
Go to Worksheet # 2 - General Environmental Worksheet
This is a simple environmental assessment meant to guide you in relevant
environmental questions. In order to respond "Yes" to Question
11, you MUST answer "No" to all 8 questions on the worksheet.
The worksheets must also be attached with the application. You will answer
"No" to the following questions about your new station: Involves
high intensity white lighting in residential neighborhoods. Is located
in an officially designated wilderness area or wildlife preserve. Threatens
the existence or habitat of endangered species. Affect places significant
to American history, architecture, etc. Affects Indian religious sites.
Is located in a floodplain. Requires construction changing surface features,
i.e. filling wetlands, deforestation, etc.
Does not comply with the FCC guidelines on RF (Radio Frequency) exposure.
Question 8 is asked to determine that your antenna will not endanger
anyone through harmful exposure to radio waves because it is mounted too
close to where they might live or work. The danger level is based solely
on the distance between your antenna and the rooftop or ground. Because
exposure drops exponentially by distance, the higher the antenna is, the
less it will generate harmful exposure. If it is above a certain height,
there is no danger at all. That is why there are minimum distances specified.
The FCC has provided a worksheet that must be submitted along with the
application.
To fill out this question, go to Worksheet # 3 - RF Exposure Worksheet
Complete the calculations on the worksheet according to the instructions.
If you are NOT putting your antenna on a tower with other broadcast
stations, that is, mounting it alone on a rooftop or other structure,
and it will not be near any other broadcast antennas, you must fill in
the distances requested in LP100 #1a and # 1b.
If you ARE CO-LOCATING your antenna on an existing tower with other
stations, you must fill in the distances requested in LP100 #2a and
# 2b.
When you have completed this worksheet, go back to complete Question
8 on the Environmental Worksheet.
When you have completed both worksheets, return to Question # 11 and
answer "Yes." This certifies that you are not subject to any
additional environmental review. Most applicants will be able to check
No in all boxes of Worksheet #2. If you have answered "Yes"
to any of the questions, then you should consult an engineer to assist
you with any additional exhibits that might be needed. If you cannot answer
"No" to all the questions on Worksheet #2, or your are unable
to conclude that your proposal will have no significant impact on the
environment, you MUST check "No" in Question #11 and prepare
a detailed Environment Assessment as an exhibit. The specific requirements
for such an exhibit are outlined in detail in FCC Instructions for FCC
Form 318.
Preparer's Certification
The last page of Section V is the certification by the person who prepared
this part of the application, because it might be an engineer or someone
different from whomever prepared the legal sections. Fill out the form
and sign it in blue ink so the FCC knows it is an original signature.
Congratulations
