Connecting an Optional Antenna
The transceiver’s antenna jack
makes it easy to use the transceiver
with a variety of antennas. Instead
of the supplied antenna, you can at-
tach a different one, such as an ex-
ternal mobile antenna or outdoor
base station antenna. Your local Ra-
dioShack store sells a variety of an-
tennas.

Always use 50-ohm coaxial cable,
such as RG-58 or RG-8, to connect
an outdoor antenna. For lengths
over 50 feet, use RG-8 low-loss di-
electric coaxial cable. If your anten-
na’s cable does not have a BNC
connector, you will also need a BNC
adapter (available at your local Ra-
dioShack store).
