Connecting an Optional External Antenna

The antenna connector on your scanner makes it easy to use the
scanner with a variety of antennas, such as an external mobile
antenna or outdoor base station antenna.
Always use 50-ohm coaxial cable, such as RG-58 or RG-8 low-
loss dielectric coaxial cable. For lengths over 50 feet, use RG-8
low-loss dielectric coaxial cable. If the antenna cable s connector
does not have a BNC connector, you will also need a BNC
adapter.
Follow the installation instructions supplied with the antenna,
route the antenna cable to the scanner, then connect it to the
antenna jack.

clockwise just past the point where the rushing sound stops. The
squelch is now set to the optimum point. Please note the position of
the squelch control for future reference. Once the squelch setting is
complete, you may press PGM to exit TUNE mode.
