CONNECTING AN

ANTENNA

There are many different types of CB antennas for mobile CBs. Each antenna type has its own benefits, so choose the one that best meets your needs. Your local RadioShack store sells a wide vari- ety of antennas.

Note: If you are using this CB as a base station, see “Using the CB as a Base Station” on Page 7.

When you choose an antenna, keep in mind that for the best performance you should mount the antenna:

•as high as possible on the vehicle

•as far as possible from sources of electrical noise

•vertically

Once you choose an antenna, follow its mounting instructions. Then route the

cable to the CB and connect the cable to the ANT. jack on the back of the CB.

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 ca- bles.

•Do not run the cable through the en- gine compartment or other areas that produce extreme heat.

For maximum range, adjust the anten- na’s Standing Wave Ratio (SWR) using an SWR meter (not supplied).

Follow the instructions supplied with the SWR meter and antenna to adjust your antenna’s SWR to the lowest possible value. SWR values of 2.0:1 are general- ly acceptable, with readings of 1.5:1 or lower being more desirable.
