2.Clean the selected windshield area, position the antenna’s clear wire on the windshield, then press firmly on both suction cups to secure it in place.

3.Route the antenna’s black cable down the edge of the windshield, around the edge of the dash, and underneath it. Be sure the cable does not interfere with the vehi- cle’s pedals or other moving parts.

4.Align the slots around the antenna’s connector with the tabs on the ANT jack. Then push the antenna’s connector and turn it clockwise until it locks into place.

Connecting an External Antenna

The ANT jack on the back of the scan- ner makes it easy to use the scanner with a variety of antennas. Instead of one of the supplied antennas, you can attach a different one, such as an exter- nal mobile antenna or outdoor base sta- tion antenna. Your local RadioShack store sells a variety of antennas.

When deciding on an antenna and its location, consider the following:

•The location of the antenna should be as high as possible.

•The antenna and antenna cable should be as far as possible from sources of electrical noise (appli- ances, other radios, and so on).

•The antenna should be vertical for the best performance.

Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor antenna. For lengths over

50feet, use RG-8 low-loss dielectric coaxial cable. If the coaxial cable’s connector does not fit in the ANT jack, you might also need a PL-259-to-BNC antenna plug adapter, such as Cat. No. 278-120. Your local RadioShack store carries a wide variety of coaxial antenna cable and connectors.

Follow the installation instructions sup- plied with the antenna, route the anten- na cable to the scanner, then connect it to the ANT BNC-type jack on the back of the scanner.
