CONNECTING AN

ANTENNA

Connecting the Telescoping

Antenna

The supplied telescoping antenna
helps your scanner receive strong lo-
cal signals. To install this antenna,
hold the antenna so it stands straight
up, then gently push the antenna’s
plug onto the ANT jack on the scan-
ner’s back panel.
The scanner’s sensitivity depends on
the antenna’s length and various envi-
ronmental conditions. Based on the
frequencies of the transmissions you
want to hear, adjust the antenna’s
length.

Connecting the Window -

Mount Antenna

You can install the supp lied window-
mount antenna on the inside of your ve -
hicle’s windshield. Follow these s t eps to
install the window-mount antenna.
Caution: Do not use the window-
mount antenna on a windshield that
has a plastic coating designed to pro-
tect passengers during an accident. If
you use the antenna on this type of
windshield, you might permanently
damage the windshield’s surface.
1. Select a location for the window-
mount antenna. Follow these
mounting guidelines when se-
lecting a location.
• The antenna’s clear wire re-
ceives signals. Mount it verti-
cally against the far right (pas-
senger) side of the windshield.
• Choose a location that does not
block the driver’s view of the
road.
• Some vehicles have Insta-
Clear® or ElectriClear® defog-
ging windshields, which have
metal coatings that interfere
with signals. General Motor’s
APV vans have a solar shield
that keeps the vehicle cooler
during the summer, which also
interferes with signals. If you
install a window-mount antenna
in a vehicle with any of these
features, the scanner probably
will not detect weak signals.
