CONNECTING THE ANTENNA

A telescoping antenna is provided with your scanner.  This antenna is
adequate for strong local signals.  To install it, simply screw it into the
hole in the top of the case.

Your scanner gets best reception results when you attach a multi-band
outdoor antenna to it.  Radio Shack sells a complete line of outdoor
scanner antennas.  To install an outdoor antenna:

1.  Select a location for the outdoor antenna that places it as high as
    possible.

2.  Following the instructions that came with the antenna and its mounting
    hardware, mount the antenna.

3.  Connect the antenna to the scanner using coaxial cable.  Always use 50
    ohm coaxial cable.  For lengths over 50 feet, use RG8 low-loss,
    dielectric coaxial cable.
