email us the general area where the radio station(s) might be located. The per-location cost includes
the license-application work, once you decide to move forward.
We will develop a list of AM frequencies
available and send them to you with our suggestions and
instructions on how to monitor them. See cost and other details
for FCC services on
Survey onsite listening.
Survey the highways where
listening is required with an automobile digital AM radio tuned
to your candidate frequencies. Monitor all the candidate
frequencies throughout the listening areas at least once during
daylight hours and at least once after dark. Report your results
to us on the
frequency-monitoring form. (See
Nighttime Monitoring Is Important.)
Choose a general location for coverage.
On a local map, find the
approximate geographic center of the listening area you want to
cover. The HAR signal will propagate to a radius of 3-5 miles
from this point in all directions. If this coverage does
not encompass the highways that require coverage,
consult with us regarding adding
satellite stations. If a
specific highway or intersection is critically important to cover,
consider locations within ½ mile. Mark the map to show the area within
which the antenna should be located to meet your coverage goals.
Consider where signs will be placed to announce to motorists entering
the area that the signal is available. (Resource: Read our TechTalk article
Tips for Placing Road Signs.)
NOTE: We do not recommend installing antennas on rooftops or
within 50 feet of buildings that contain electronics because of
the potential for interference and equipment damage. This does
not apply to non-building oriented situations such as
isolated-style installations in which a cabinet with the
electronic equipment is attached to the antenna support pole.

For best coverage, the
immediate location should be free of objects that exceed 25 feet
(about 2 stories.) This includes tall buildings, trees, terrain
features, lighting, power and communication poles and towers,
overpasses and highway signs. Make certain 120VAC power and
telephone service are available at the site and that there is a
40'-by-40' area of open ground for cabinet and antenna
installation. A conventional, vertical profile or super antenna
system may be used. Consult ISS for assistance.
Fill out the FCC license applications questionnaire.
Complete a FCC License
Questionnaire found on
webpage that gives us the information needed to prepare and
submit the 10-year FCC license application on your
behalf. On the questionnaire, you will be asked to
provide information on your antenna operating area, your
frequency choice and required names and addresses. The
FCC typically takes 3 to 6 months to process authorize
it. While waiting for the
10-year license to be granted, you may procure the equipment and
build the station, if you wish.
IMPORTANT: You must have a FCC
license in hand to operate; the station must be on the air
within 12 months of the license grant date, or the authorization
will expire. Special Temporary Licenses (STA) might also be
available from the FCC, if immediate operation is required.
NOTE 1: Because FCC
processing time is unpredictable, we recommend you
request licensing and other FCC documentation services
as soon as you know for sure you will have a station –
definitely no later than when you place your radio equipment order.
NOTE 2: The FCC considers 10-year, renewable licenses for
Information Radio Stations secondary to full-power
broadcast stations. This means, that in a rare situation
in which a full-power station might move into a given
area, an advisory radio station already in that vicinity
might need to change frequency. We can assist.
