Antenna installation
To obtain the best performance from your CB radio is important to install a good quality antenna.
•You should purchase a suitable mobile antenna designed for the 27MHz frequency band.
•Connect the antenna to the rear antenna socket using a PL259 coaxial connector.
•Where necessary, solder the connector carefully at the inner connector of the coaxial cable
and avoids any short circuit with one of the thin copper wires of the outer coaxial shielding.
•To obtain maximum performance from the transceiver, mount the antenna in a suitable position
for good and free radiation from the metallic car surface.
•Standard mobile antenna needs a good car body ground connection for best efficiency.Most
standard mobile antennas cannot work without car body ground connection!
•Most CB antennas need fine tuning for best SWR (Standing wave ratio)
•Special ground less antenna are obtainable for motor homes or trucks in cases where the an-
tenna position is made from plastic or fiberglass or where a grounding is not possible. Such
antenna do only work on fiberglass or plastic car body structures and do not work immediately
on metallic structures.
•Do not use any transmit function (example PTT) before installing the antenna.
Antenna SWR information
For radio communications, each antenna should have a good matching to avoid too much en-
ergy loss across the transmission lines or defects of transmitter stages or power amplifiers
A good antenna obtains an SWR(Standing Waver Ratio) of 1.5 or even better.
This means that most of the transmitting power is forwarded correctly from transmitter via cable
to the antenna, and that the amount of reflected power is small.
