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

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.
