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.
• Install iDEN and 800 MHz cellular RAUs so that their antennas will be at
least 6 to 8 meters (20 to 26 feet) apart. Separation is required to reduce signal
interference between the two frequency bands.
Connecting the Antenna to the RAU
Connect a passive antenna to the SMA male connector on the RAU using coaxial
cable.
CAUTION:When connecting to the SMA female connector on
the RAU and passive antenna, DO NOT over-tighten the connec-
tor. Firmly hand-tightening the connector is adequate.
CAUTION:Do not connect an antenna that is installed in an out-
door location to an RAU.
