Antenna Configurations
When attaching the supplied ½ Wave Omni-directional Whip antenna directly to the back of the BaseStation, always ensure
that the antenna are firmly seated, are not cross threaded, and are located away from any metal obstructions. Keep the
antenna away from walls or other significant structures by at least 24 inches.
Option 1
Install the BaseStation in the center of the area
of communication, with antenna installed on
the back of the BaseStation, having a clear
line of sight in all directions.
Option 2
Install the BaseStation in a convenient
location and use an optional LMR-400, a 50
ohm coax cable up to 25 ft to connect an
optional directional antenna. (15 ft of LMR-
400 induces about 1 dB of attenuation.)
Note:
Directional antennas are subject to legal
restrictions in some countries.
Option 3
Install the BaseStation in an equipment rack
(1 RU) and use an optional LMR-195, a 50
ohm coax up to 10 ft to mount the antenna
above the equipment rack. (5 ft of LMR-195
coax induces about 1 dB of attenuation.)
