point of the nearest airport runway. Differences in ground
elevation 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. Warning: Installation and removal of CB station antennas
near powerlines is dangerous. For your safety, follow the
installation directions included with your antenna.
Sec. 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 transmitter 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, Sec. 95.425).
Any internal modification to a certificated CB transmitter cancels
the certification, and use of such a transmitter voids your
authority to operate the station.
Sec. 95.410 (CB Rule 10) How much power may I use?
(a) Your CB station transmitter power output must not exceed
the following 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 excess of that authorized voids your authority to
operate the station.
Sec. 95.411 (CB Rule 11) May I use power amplifiers?
(a) You may not attach the following items (power amplifiers)
to your certificated CB transmitter in any way:
1. External radio frequency (RF) power amplifiers (sometimes
called linears or linear amplifiers); or
2. Any other devices which, when used with a radio trans-
mitter as a signal source, are capable of amplifying the
signal.
(b) There are no exceptions to this rule and use of a power
amplifier voids your authority to operate the station.
(c) The FCC will presume you have used a linear or other
external RF power amplifier if:
1. It is in your possession or on your premises; and
