Connecting an Optional Antenna
The antenna connector on your scanner makes it easy to
use the scanner with a variety of antennas. Instead of the
supplied antenna, you can attach a different one, such as
an external mobile antenna or outdoor base station anten-
na. Your local RadioShack store sells a variety of anten-
nas.
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 an-
tenna’s cable does not have a BNC connector, you will
also need a BNC adapter (also available at your local Ra-
dioShack store).
Follow the installation instructions supplied with the anten-
na, route the antenna cable to the scanner, then connect
it to the
ANT jack.
Warning: Use extreme caution when installing or remov-
ing 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, contact with the antenna, mast, ca-
ble or guy wires can cause electrocution and death! Call
the power company to remove the antenna. Do not at-
tempt to do so yourself.
