CONNECTING AN
ANTENNA
You can connect either the supplied
telescoping antenna or an optional
antenna.
Telescoping Antenna
To attach the telescoping antenna,
simply screw it into the hole on top of
your scanner.
The antenna’s length controls its
sensitivity. Adjust the length of the
telescoping antenna as follows for
the best reception.
29-54 MHz Extend all 3 seg-
ments
108-174 MHz Extend only 2 seg-
ments
406-956 MHz Collapse Fully (only
1 segment extend-
ed)
Optional Outdoor Antenna
The supplied antenna is usually ade-
quate for strong, local signals. How-
ever, for the best results in receiving
weaker, more distant signals on all
bands, you can attach an optional
outdoor antenna (not supplied), such
as a mobile, telescoping, multi-band,
or outdoor base antenna.
Warning: When installing or remov-
ing an outdoor antenna, follow all
cautions and warnings included with
the antenna.
Notes:
• This scanner uses a BNC
antenna connector. If the coaxial
cable’s connector does not fit
the
ANT
jack, you might also
need an adapter. Your local
Radio Shack store sells a com-
plete line of outdoor antennas,
adapters, BNC connectors, and
mounting hardware.
• Always use 50-ohm coaxial
cable to connect an outdoor
antenna. For lengths under 50
feet, use RG58 (Cat. No. 278-
1314) or RG8/M (Cat. No. 278-
1313). For lengths over 50 feet,
use RG-8, low-loss coaxial cable
(Cat. No. 278-1312).
