- If you already have a radio-telephone antenna installed, the CB antenna
should be higher than this.
- There are two types of antenna: pre-regulated which should be used on a
good ground plane (e.g. car roof or lid of the boot), and adjustable which
offer a much larger range and can be used on a smaller ground plane (see
§ 4, Adjustment of SWR).
- For an antenna which must be fixed by drilling, you will need a good contact
between the antenna and the ground plane. To obtain this, you should lightly
scratch the surface where the
screw and tightening star are to
be placed.
- Be careful not to pinch or flatten
the coaxial cable (as this runs the
risk of break down and/or short-
circuiting).
- Connect the antenna to the
adapter.
c) Fixed antenna
- A fixed antenna should be installed in a clear space as possible. If it is fixed to
a mast, it will perhaps be necessary to stay it, according to the laws in force
(you should seek professional advice). All PRESIDENT antennas and acces-
sories are designed to give maximum efficiency to each CB radio within the
range.
3) BASIC OPERATIONS TO BE CARRIED OUT BEFORE USING
YOUR SET FOR THE FIRST TIME (without transmitting and
without using the «push-to-talk» switch)
a) Check the antenna connections.
b) Turn the set on by turning the Power knob (12) clockwise.
c) Set the squelch OFF. See § 16.1 page 10.
d) Adjust the volume to a comfortable level.
e) Go to channel 20 by using the channel selectors (5 & 8).
4) ADJUSTMENT OF SWR (Standing wave ratio)
WARNING: This must be carried out when you use your CB radio for the first
time (and whenever you re-position your antenna). The adjustment must be
carried out in an obstacle-free area.
* Adjustment with external SWR-meter (e.g. TOS-1 PRESIDENT)
a) To connect the SWR meter:
- Connect the SWR meter between the CB radio and the antenna as close as
possible to the CB (use a maximum of 40 cm cable, type President CA 2C).
b) To adjust the SWR meter:
- Set the CB to channel 20.
- Put the switch on the SWR-meter to position FWD (calibration).
- Press the «push-to-talk» switch on the microphone to transmit.
- Bring the index needle to by using the calibration key.
