Connecting an Outdoor Antenna

Connecting an Outdoor Antenna

Instead of the supplied antenna, you can connect an outdoor base-station or mobile antenna (not supplied) to your scanner using a BNC connector. Your local RadioShack store sells a va- riety of antennas. Choose the one that best meets your needs.

When deciding on a mobile or base-station antenna and its loca- tion, consider these points:

•The antenna should be as high as possible on the vehicle or building.

•The antenna and its cable should be as far as possible from sources of electrical noise, such as appliances or other radios.

•The antenna should be vertical for the best performance.

Always use 50 Ohm coaxial cable, such as RG-58 or RG-8, to connect the base-station or mobile antenna. For lengths over 50 feet, use RG-8 low-loss dielectric coaxial cable. If the antenna cable’s connector does not fit in the scanner’s antenna jack, you might also need a PL-259-to-BNC antenna plug adapter. Your local RadioShack store carries a wide variety of coaxial antenna cable and connectors.

If you choose another antenna, remove the supplied antenna and follow the mounting instructions supplied with the new an- tenna. Route the antenna’s cable to the scanner, then connect the cable to the scanner’s antenna jack.

Cautions:

•Do not run the cable over sharp edges or moving parts that might damage it.

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