CONNECTING AN

ANTENNA

You can connect either the supplied telescoping antenna or an optional an- tenna to your scanner.

Telescoping Antenna

The supplied telescoping antenna helps your scanner receive strong lo- cal signals. Follow these steps to in- stall the supplied antenna.

ANT

1. Hold the antenna so it stands straight up.

2. Gently push the antenna’s plug onto the ANT jack on the scan- ner’s back panel.

The antenna’s length affects recep- tion. Adjust the antenna’s length as follows for the best results.

29–150 MHz	Extend fully
150–174 MHz	Extend only 3 seg-
	ments
216–406 MHz	Extend only 2 seg-
	ments
406–1000 MHz	Collapse Fully (only
	1 segment extended)

Optional Outdoor Antenna

The supplied antenna is usually good for strong, local signals. However, for the best results in receiving weaker, more distant signals on all bands, you can attach an optional outdoor anten- na (not supplied), such as a mobile, telescoping, multi-band, or outdoor base antenna.

Warning: When installing or removing an outdoor antenna, follow all cautions and warnings included with the anten- na.
