things to consider in setting up an ITS6000 HAR
service in your area. Feel free to email us for
personal planning assistance (or call Bill Baker
at 616.772.2300 Ext 102). We have a network of
representatives across the country; and, after
initial brainstorming, we can put you in touch
with one in your area who can visit your
site(s), help test frequencies and find the best
antenna location(s) — even install the system —
whatever is needed.
Step 1: Order a frequency search.
To order a
frequency search, just
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 this webpage.
Step 2: Survey onsite listening.
highways where listening is required with an
automobile digital AM radio tuned to your
candidate frequencies. Monitor all the candidate
frequencies throughout the listening area at
least once during daylight hours and once after
dark. Report your results to us on
this frequency-monitoring form. (See why
nighttime monitoring is important in
Step 3: Choose a general location for
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

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
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.
Step 4: Determine your desired 'All
Hazard' warning coverage area.

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 us for assistance.
Step 6: Complete the FCC License
FCC License Questionnaire found on
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

Information Radio Stations is a generic term synonymous with Travelers
Information Stations (TIS), Highway Advisory Radio Stations (HAR) /
Highway Information Systems & Low Power Radio Stations (LPR). Operation
of the stations is governed by FCC Part 90.242 Rules. A FCC license is
required. Information Radio Stations may be fixed or portable.
Subcomponents may include transmitter, antenna and ground system,
digital voice player, wattmeter, cabinet with conventional or Corbin
locks, lightning arrestors for RF, power and telephone lines, coaxial
cable. Most stations employ black maximized antennas to discourage ice
accumulation and security measures to prevent unauthorized program
access. Options include synchronization, battery backup, solar power,
remote programming by local, network or telco, multi-station audio
distribution via RF or LAN / WAN or wireless network.
