Connecting Earphone/Headphones - Radio Shack PRO-89 Owner's Manual

• The antenna should be
vertical for the best
performance.
Always use 50 Ohm coaxial cable,
such as RG-58 or RG-8, to
connect the base-station or mobile
antenna. For lengths over 50 feet,
use RG-8 low-loss dielectric
coaxial cable. If the antenna
cable's connector does not fit in
the scanner's antenna jack, you
might also need a PL-259-to-BNC
antenna plug adapter. Your local
RadioShack store carries a wide
variety of coaxial antenna cable
and connectors.
Once you choose an antenna,
follow the mounting instructions
supplied with the antenna, after
removing a supplied antenna.
Then route the antenna's cable to
the scanner and connect the cable
to the scanner's antenna jack.

WARNING
Use extreme caution
when you install or
remove an outdoor
antenna. If the antenna
starts to fall, let it go! It
could contact overhead
power lines. If the
antenna touches a
power line, contact with
the antenna, mast,
cable, or guy wires can
cause electrocution and
death. Call the power
company to remove the
antenna. DO NOT
attempt to do so
yourself.
