Connecting an Optional Antenna

The supplied telescoping antenna re- ceives strong, local signals. Howev- er, to receive weaker, more distant signals in all bands, you can attach an optional antenna, such as an ex- ternal mobile antenna or outdoor base station antenna. Your local Ra- dioShack store sells a variety of an- tennas.

Note: If you connect an external an- tenna, remove the telescoping an- tenna from the top of the scanner.

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 your antenna’s cable does not have a BNC connector, use a BNC adapter available at your local RadioShack store.

Follow the installation instructions supplied with the antenna, route the antenna cable to the scanner, then connect it to the ANT jack on the back of the scanner.

Warning: Use extreme caution when installing or removing an outdoor an- tenna. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches a power line, contact with the antenna, mast, cable or guy wires can cause electro- cution and death! Call the power company to remove the antenna. Do not attempt to do so yourself.

Cautions:

•Do not run the cable over sharp edges or moving parts.

•Do not run the cable next to power cables or other antenna cables.

•Do not run the cable through areas that produce extreme heat.

•Follow all cautions and warnings included with the antenna.
