step 3: connect your scanner

connecting the supplied antenna

Plug the telescoping antenna into the ANT connector. The antenna length should be as shown below.

Frequency

25-174 MHz

Extend fully (4 segments)

400-512 MHz

Extend 2 segments

806-1300 MHz

Collapse fully (1 segment)

connecting an external antenna

The ANT jack on the back of the scanner makes it easy to use the scanner with a variety

of antennas.

You will need to connect an external antenna when

you mount your scanner in the dashboard of your vehicle. You may also

want to connect an external antenna if you use your scanner as a base station.

Your local RadioShack store sells a variety of antennas. Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor antenna. For lengths exceeding 50 feet, use RG-8 low-loss dielectric coaxial cable. If your coaxial cable does not have a BNC connector, you will also need a BNC adapter (not supplied).
