Connecting an Optional Antenna

The TRC-239 comes with a flexible antenna (equipped with a BNC connector) that is ideal for most applications. However, the BNC connector makes it easy to connect other types of antennas, too. For mobile or base station use, you might want to connect an optional external antenna. Your local RadioShack 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 (appliances, other radios, and so on).

•The antenna should be vertical for the best per- formance.
