CONNECTING THE ANTENNA

Follow these steps to attach the supplied flexible antenna to the connector on the top of your scan- ner.

1. Align the slots around the antenna’s connec- tor with the tabs on the jack.

2. Press the antenna down over the jack and rotate the antenna’s base clockwise until it locks into place.

Connecting an Optional Antenna

The antenna connector on your scanner makes it easy to use the scan- ner with a variety of antennas. Instead of the supplied antenna, you can attach an external mobile antenna or outdoor base antenna (for example). 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 over 50 feet, use RG-8 low-loss di- electric coaxial cable. If your antenna’s cable does not have a BNC connector, you will also need a BNC adapter (available at your local RadioShack store).

Warning: When you install an outdoor antenna, use extreme cau- tion. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches the power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to remove the antenna. Do not at- tempt to remove it yourself!
