Installing Passive Antennas
Refer to the manufacturer’s installation instructions to install passive antennas.
Passive antennas are usually installed below the ceiling. If they are installed above
the ceiling, the additional loss due to the ceiling material must be considered when
estimating the antenna coverage area.
Considerations:
• Use coaxial cable with the least amount of loss possible.
• Keep iDEN and 800 MHz cellular antennas 6 to 8 meters (20 to 26 ft) apart.
Connecting the Antenna
Connect a passive antenna to the SMA female connector on the RAU. The following
figure shows connecting an optional antenna to a single band RAU.
CAUTION:When connecting to the SMA female connector on the RAU
and passive antenna, DO NOT over-tighten the connector. Firmly
hand-tightening the connector is adequate.
NOTE: If an RAU is installed but an antenna is not connected, the SMA port must
be terminated with a 50 ohm terminator (LGC part number 4100).
