Connecting the Antenna

To attach the supplied flexible antenna to the connector on the top of your scanner, simply screw it onto the scanner's SMA connector.

Connecting an Optional Antenna

The scanner's SMA 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- or 75-ohm, RG-58, or RG-8, coaxial cable and the supplied BNC/SMA adapter to connect an outdoor antenna. If the antenna is over 50 feet from the scanner, use RG-8 low-loss dielectric coaxial cable. Cable loss increases with higher frequency.

Connecting an Earphone/Headphone

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

See “Earphone Warning” at the front of the manual for important information about using an earphone/ headphone.

Connecting an Extension Speaker

In a noisy area, an optional amplified 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!

Never connect anything other than an earphone or the recommended amplified extension speaker to the scanner’s headphone jack. This might damage the scanner.
