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 (also available at your local Ra-
dioShack store).
Follow the installation instructions supplied with the an-
tenna, route the antenna cable to the scanner, then con-
nect 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.
CONNECTING AN EARPHONE/
HEADPHONES
For private listening, you can plug an earphone or mono/
stereo headphones (not supplied), available at your local
RadioShack store, into the jack on top of your scan-
ner. This automatically disconnects the internal speaker.
