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.
