Proprietary and Confidential
Remote Mount High Gain (8.15dBi) 900MHz Antenna on a Standard
Collector or Repeater
Warning Do not install an 8.15 dBi antenna directly on the CCU/repeater.
Antenna installation directly on the CCU will compromise mechanical
integrity and will not meet the compliance requirement for a loss of 2.2 dB
between the CCU/repeaters and the 8.15 dBi antenna.
The following Coaxial Specifications table lists several options for coaxial cable that can
be used with the remote mount high gain 900 MHz antenna. When a high gain antenna is
installed on a standard collector or repeater, follow the FCC set limits for the maximum
transmit power of the collector or repeater. To meet FCC limits, standard collectors or
repeaters must have a minimum of 2.2 dB worth of loss (but not more than 3.5 dB)
between the collector or repeater and the antenna.
Allow 0.1 dB loss for each connector. If required, you may use a 1 dB attenuator (similar
to the Pasternack PE7002-1) to attain the desired power at the antenna for short coaxial
cable runs.
Remote Mount High Gain (8.15 dBi) 900 MHz Antenna on a Tower
CCU
The following Coax Specification table lists several options for coaxial cable that can be
used with the remote mount high gain 900 MHz antenna. When a high gain antenna is
installed on a tower collector, follow the FCC set limits for the maximum transmit power
of the collector. To meet these limits, tower collectors with FCC ID number
EO9CCU100T must have a minimum of 2.2 dB worth of loss (but not more than 3.5 dB)
between the tower cabinet and the antenna. Install all other tower collectors with
minimum cable loss.
Allow 0.1 dB loss for each connector. If required, you may use a 1 dB attenuator (similar
to the Pasternack PE7002-1) to attain the desired power at the antenna.
