Connecting an Optional
Antenna
The antenna connector on your
scanner makes it easy to use the
scanner with a variety of
antennas, such as an external
mobile antenna or outdoor base
station antenna. Your local
RadioShack store sells a variety of
antennas.
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 dielectric coaxial cable. If
your antenna's cable does not
have a BNC connector, you will
also need a BNC adapter (not
supplied, available at your local
RadioShack store).
Follow the installation instructions
supplied with the antenna, route
the antenna cable to the scanner,
then connect it to the antenna
jack.

WARNING
o
Use extreme caution
when installing or
removing an outdoor
antenna. If the
antenna starts to fall,
let it go! It could
contact overhead
power lines. If the
antenna touches a
power line, touching
the antenna, mast,
cable, or guy wires
can cause
electrocution and
death. Call the power
company to remove
the antenna. DO
NOT attempt to do
so yourself.
