System information

Antenna Placement
Antenna Power
Antenna Faults
The AXT630, AXT400, and AXT600, antenna ports A and B provide a DC bias output of 12-15 V DC to power active
antennas. Set the DC power to off when using passive (non-powered) antennas.
The antenna input status LED flashes red to indicate a short at an antenna port.
To isolate the fault, navigate to the Antenna Power menu. The menu displays
which antenna port (A, B, or A+B) is the source of the fault. Check the antenna
connections to remove the fault condition.
To set the antenna voltage, navigate to the Antenna Power menu and use the
arrow keys to select one of the following options:
• On: Antenna Power = 12-15 V DC
• Off: Antenna Power = 0 V DC
The following sections cover routing the RF antenna signal to receivers, Spectrum Managers, and antenna distribution
systems.
Proper antenna placement has an enormous impact on RF system performance. In general, receiver antennas should be
at least six feet above ground level and at least six feet away from other antennas. Maintain a clear line-of-sight between
transmitters and receiver antennas. Avoid placing antennas near walls or other reflective surfaces.
Options for antenna placement include the following:
• Front-mounted on a rack component
• Remote mounted above crowd level
• Shared antenna signal from an antenna distribution system
