2. Clean the selected windshield
area, position the antenna’s clear
wire on the windshield, then press
firmly on both suction cups to
secure it in place.
3. Route the antenna’s black cable
down the edge of the windshield,
around the edge of the dash, and
underneath it. Be sure the cable
does not interfere with the vehi-
cle’s pedals or other moving parts.
4. Align the slots around the
antenna’s connector with the tabs
on the
ANT
jack. Then push the
antenna’s connector and turn it
clockwise until it locks into place.
Connecting an External
Antenna
The
ANT
jack on the back of the scan-
ner makes it easy to use the scanner
with a variety of antennas. Instead of
one of the supplied antennas, you can
attach a different one, such as an exter-
nal mobile antenna or outdoor base sta-
tion antenna. Your local RadioShack
store sells a variety of antennas.
When deciding on an antenna and its
location, consider the following:
• The location of the antenna
should be as high as possible.
• The antenna and antenna cable
should be as far as possible from
sources of electrical noise (appli-
ances, other radios, and so on).
• The antenna should be vertical for
the best performance.
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 the coaxial cable’s
connector does not fit in the
ANT
jack,
you might also need a PL-259-to-BNC
antenna plug adapter, such as Cat.
No. 278-120. Your local RadioShack
store carries a wide variety of coaxial
antenna cable and connectors.
Follow the installation instructions sup-
plied with the antenna, route the anten-
na cable to the scanner, then connect
it to the
ANT
BNC-type jack on the
back of the scanner.
