Setting Up Your Scanner
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.
