Connecting an Optional
Antenna
The supplied telescoping antenna re-
ceives strong, local signals. Howev-
er, to receive weaker, more distant
signals in all bands, you can attach
an optional antenna, such as an ex-
ternal mobile antenna or outdoor
base station antenna. Your local Ra-
dioShack store sells a variety of an-
tennas.
Note:
If you connect an external an-
tenna, remove the telescoping an-
tenna from the top of the scanner.
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, use
a BNC adapter 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
ANT
jack on the back
of the scanner.
Warnin
g
:
Use extreme caution when
installing or removing an outdoor an-
tenna. 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,
cable or guy wires can cause electro-
cution and death! Call the power
company to remove the antenna. Do
not attempt to do so yourself.
Cautions
:
• Do not run the cable over sharp
edges or moving parts.
• Do not run the cable next to
power cables or other antenna
cables.
• Do not run the cable through
areas that produce extreme
heat.
• Follow all cautions and warnings
included with the antenna.
