Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor
antenna. For length over 50 feet, use RG-8 low-loss dielectric coaxial cable. If your
antenna’s cable does not have a BNC connector, you will also need a BNC adapter (not
supplied, available at your local RadioShack store).
Follow the installation instructions supplied with the antenna, route the antenna cable to
the scanner, then connect it to the antenna jack.
WARNING
Use extreme caution when installing or removing 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, touching 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.
Connecting an Earphone/Headphones
For private listening, you can plug an 1/8-inch (3.5 mm) mini-plug earphone or
headphones (not supplied), available at your local RadioShack store, into the
HEADPHONE jack on top of your scanner. This automatically disconnects the internal
speaker.
Connecting an External Speaker
In a noisy area, an amplified speaker (not supplied), available at your local RadioShack
store, might provide more comfortable listening. Plug the speaker cable’s 1/8-inch (3.5
mm) mini-plug into your scanner’s HEADPHONE jack.
Note
• You must use an amplified speaker with this scanner. Non-amplified speakers do not
provide sufficient volume for comfortable listening.
