Connecting An Antenna - Radio Shack HTX-252 Owner's Manual

CONNECTING AN ANTENNA

You must install an antenna before you can operate the trans-
ceiver. There are many different types of antennas suitable for
transceiver use. Each has its own benefits, Choose the one best
suited to your particular needs. Your local RadioShack store has
a wide selection from which to choose.
Note: If you are using the transceiver as a base station, see "Us-
ing the Transceiver as a Base Station" on Page 13.
When you install an antenna, keep in mind that, for the best per-
formance, you should mount the antenna vertically as high as
possible on the vehicle and away from sources of electrical noise.
Once you choose an antenna, follow it's mounting instructions.
Then route the cable to the transceiver and thread the cable onto
the connector on the back of the transceiver.

Cautions:
• Avoid routing the cable next to sharp edges or moving
parts, which might damage the cable.
• Do not run the cable next to power cables or other radio
antenna cables.
• Do not run the cable through the engine compartment or
other areas that produce extreme heat.
To take advantage of your transceiver's maximum range, adjust
the antenna's standing wave ratio (SWR) using an SWR meter
(not supplied, available at your local RadioShack store). Follow
the instructions supplied with the SWR meter and antenna to ad-
just the antenna's SWR. Values of 2.0:1 are generally accept-
able, with readings of 1.5:1 or lower being more desirable.
