from the receiver antenna, you may be able to increase
range by doing one of the following:
Reduce interference (see above).
Increase transmitter RF power level.
Use Normal mode instead of High Density mode.
Use an active directional antenna, antenna
distribution system, or other antenna accessory to
increase RF range.
Eliminating RF Overload
If you see the red RF LED on a receiver, try the following:
Reduce the transmitter RF power level
Move the transmitter further away from the receiver—
at least 6 m (20 ft)
If you are using active antennas, reduce antenna or
amplifier gain.
Use omnidirectional antennas
Antenna Faults
The Antenna
Fault message indicates a short circuit
condition at an antenna port.
Check antennas and cables for damage
Ensure that antenna ports are not overloaded
Check antenna bias voltage setting. Turn off voltage
if using passive antennas.
