Connecting an Optional Antenna
The scanner's BNC connector makes it easy to
connect a variety of optional antennas, including an
external mobile antenna or outdoor base station
antenna.
Note: Always use 50-ohm, RG-58, or RG-8, coaxial
cable to connect an outdoor antenna. If the antenna
is over 50 feet from the scanner, use RG-8 low-loss
dielectric coaxial cable. You can get a BNC adapter
at your local electronics store.

Connecting an Earphone/Headphone

For private listening, you can plug a 1 / -inch (3.5
8
mm) mini-plug earphone or mono headphones (not
supplied) into the headphone jack on top of your
scanner. This automatically disconnects the internal
speaker.

Connecting an Extension Speaker

In a noisy area, an optional extension speaker,
positioned in the right place, might provide more
comfortable listening. Plug the speaker cable's 1 / -
8
inch (3.5-mm) mini-plug into your scanner's jack.
WARNING!
If you connect an external speaker to the scanner's
headphone jack, never connect the audio output line
to a power supply and ground. This might damage
the scanner.
