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).
