port and the transceiver.
RFU Transmit
Branching Unit Loss
Only displayed when RFU Installation Platform is set to ‘IRFU-
HP’.
The transmitter branching unit loss between the transceiver
and IRFU waveguide port.
Antenna
Antenna Gain The gain (dBi) of the main antenna.
RF Feeder Loss The loss (dB) in the feeder (waveguide) between the RFU and
antenna, including loss of couplers. This should be zero for a
direct mount configuration with no coupler. Waveguide
specifications are provided in Flexible waveguide
specifications on page 4-10.
Diverse Antenna Gain Only displayed when RFU Installation Platform is set to ‘IRFU-
HP’ and RFU Branching Configuration is set to
‘RFU 1+1 Tx MHSB / Rx SD’.
The gain (dBi) of the diverse antenna.
Diverse RF Feeder Loss Only displayed when RFU Installation Platform is set to ‘IRFU-
HP’ and RFU Branching Configuration is set to
‘RFU 1+1 Tx MHSB / Rx SD’.
The loss (dB) in the feeder (waveguide) between the IRFU and
diverse antenna.
IF Cable
IF Cable Length The total length of the IF cable from the RFU to the CMU in
meters or feet as appropriate. The maximum permitted length
is 190 meters (620 ft) for standard IF cable.
If the IF cable length is between 190 and 300 meters (620
ft and 980 ft), contact Technical Support.
