When deciding on a mobile or base-station antenna and its loca-
tion, consider the following:

•

The antenna should be mounted as high as possible.

•

The antenna and antenna cable should be as far as possible
from sources of electrical noise (appliances, ignition sys-
tems, gauges, and so on).

•

The antenna should be vertical for the best performance.

When connecting an optional antenna, always use 50-ohm coax-
ial cable, such as RG-58 (Cat. No. 278-1314) or RG-8/M (Cat. No.
278-1313). For lengths over 50 feet, use RG-8 low-loss dielectric
coaxial cable (Cat. No. 278-1312). If the coaxial cable’s connector
does not fit in the scanner’s

ANT

jack, you might also need a PL-

259-to-BNC antenna plug adapter, such as Cat. No. 278-120.
Your local Radio Shack store carries a wide variety of coaxial an-
tenna cable and connectors.

Follow the mounting instructions supplied with the antenna. Then
route the antenna cable to the scanner, and connect it to the

ANT

jack on the top of the scanner.

Cautions:

•

Do not route the cable over sharp edges or moving parts.

•

Do not run the cable next to power cables.

•

Do not run the cable through a vehicle’s engine compart-
ment or other areas that produce extreme heat.
