channels, give priority to emergency
communication messages concerning
the immediate safety of life or the im-
mediate protection of property.
(d) You may use any channel for
emergency communications or for
traveler assistance.
(e) You must share each channel with
other users.
(f) The FCC will not assign any chan-
nel for the private or exclusive use of
any particular CB station or group of

§ 95.408
(CB Rule 8) How high may I
put my antenna?
(a)
Antenna
means the radiating sys-
tem (for transmitting, receiving or
both) and the structure holding it up
(tower, pole or mast). It also means ev-
erything else attached to the radiating
system and the structure.
(b) If your antenna is mounted on a
hand-held portable unit, none of the
following limitations apply.
(c) If your antenna is installed at a
fixed location, it (whether receiving,
transmitting or both) must comply
with either one of the following:
(1) The highest point must not be
more than 6.10 meters (20 feet) higher
than the highest point of the building
or tree on which it is mounted; or
(2) The highest point must not be
more than 18.3 meters (60 feet) above
the ground.
(d) If your CB station is located near
an airport, and if you antenna struc-
ture is more than 6.1 meters (20 feet)
high, you may have to obey additional
restrictions. The highest point of your
antenna must not exceed one meter
above the airport elevation for every
hundred meters of distance from the
nearest point of the nearest airport
runway. Differences in ground ele-
vation between your antenna and the
airport runway may complicate this
formula. If your CB station is near an
airport, you may contact the nearest
FCC field office for a worksheet to help
you figure the maximum allowable
height of your antenna. Consult part 17
of the FCC’s Rules for more informa-
tion.

ARNING
: Installation and removal of CB
station antennas near powerlines is dan-
gerous. For your safety, follow the installa-
tion directions included with your antenna.

§ 95.409
(CB Rule 9) What equipment
may I use at my CB station?
(a) You must use an FCC certificated
CB transmitter at your CB station.
You can identify an FCC certificated
transmitter by the certification label
placed on it by the manufacturer. You
may examine a list of certificated
equipment at any FCC Field Office or
at FCC Headquarters. Use of a trans-
mitter which is not FCC certificated
voids your authority to operate the
station.
(b) You must not make, or have
made, any internal modification to a
certificated CB transmitter. (See CB
Rule 25, § 95.425). Any internal modi-
fication to a certificated CB trans-
mitter cancels the certification, and
use of such a transmitter voids your
authority to operate the station.

§ 95.410
(CB Rule 10) How much power
may I use?
(a) Your CB station transmitter
power output must not exceed the fol-
lowing values under any conditions:
AM (A3)—4 watts (carrier power) SSB—12
watts (peak envelope power)
(b) If you need more information
about the power rule, see the technical
rules in subpart E of part 95.
(c) Use of a transmitter which has
carrier or peak envelope power in ex-
cess of that authorized voids your au-
thority to operate the station.
§ 95.411
(CB Rule 11) May I use power
amplifiers?
(a) You may not attach the following
items (power amplifiers) to your cer-
tificated CB transmitter in any way:
(1) External radio frequency (RF)
power amplifiers (sometimes called
linears or linear amplifiers); or
