To connect the telescopic antenna, simplyconnect it to the BNC type ANT. connector on the rear of the scanner. You can purchase avariety of scanner antennas for both mobile and base station available at a local electronicsstore. Choose the one that best meets your needs.When deciding on a mobile or base station antenna and its location, consider these points.• The antenna should be as high as possible on a vehicle or a house.• The antenna and its cable should be as far as possible from sources of electrical noise(ignition systems, gauges, and so on).• The antenna should be vertical for the best performance.Mounting an AntennaOnce you choose an antenna, follow the mounting instructions supplied with the antenna.Then route the antenna cable to the scanner.The antenna connector on your scanner makes it easy to use the scanner with a variety ofantennas, such as an external mobile antenna or an outdoor base station antenna.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 dielectric coaxial cable If your antenna’s cabledoes not have a BNC connector, you will also need a BNC adapter (available at a localelectronics store).Follow the Installation instructions supplied with the antenna, route the antenna cable to thescanner, then connect it to the ANT. jack.Warning: Use extreme caution when you install or remove an outdoor antenna. If theantenna starts to fall, let it go! It could contact overhead power lines. If theantenna touches a power line, contact with the antenna, mast, cable, or guywires can cause electrocution and death. Call the power company to removethe antenna.
