Remote Mount High Gain (8.15dBi) 915 MHz Antenna on a Standard Collector
or Repeater
Warning! Do not install an 8.15 dBi antenna directly on the CCU or 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 or
Repeater 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 915 MHz antenna. When a high gain antenna is installed on a
standard collector or repeater, follow the FCC and ISED set limits for the maximum transmit
power of the collector or repeater. To meet FCC and ISED 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) 915 MHz Antenna on a Tower CCU
The following Coaxial Specification table lists several options for coaxial cable that can be used
with the remote mount high gain 915 MHz antenna. When a high gain antenna is installed on a
tower collector, follow the FCC and ISED set limits for the maximum transmit power of the
collector. To meet these limits, tower collectors 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.
