Connecting an Optional

Antenna

Your walkie talkie comes with a flexible antenna that is ideal for most applications. However, the walkie talkie’s antenna jack makes it easy to connect other types of antennas, too. For mobile or base station use, you might want to connect an option- al external antenna. Your local Ra- dioShack store carries a wide selection of external mobile or outdoor base- station antennas. Choose the one that best meets your needs.

When deciding on a mobile or base- station 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.

Note: When connecting an optional an- tenna, always use 50-ohm coaxial cable, such as RG-58 or RG-8. For lengths over

50feet, use RG-8 low-loss dielectric coax- ial cable. If the coaxial cable’s connector does not fit into the antenna jack, you might also need a PL-259-to-BNC anten- na plug adapter, such as Cat. No. 278-

120.Your local RadioShack store carries a wide variety of coaxial antenna cable and connectors.
