Downlink
The downlink signal is received from the radiating cable and enters the Downlink Input Shelf 80-
301407 where by means of crossband splitter/couplers it is split into VHF, UHF and 800MHz paths,
the UHF path is further split into Low, Middle and Highband paths.
The VHF and UHF LowBand paths leave Downlink Input Shelf 80-301407. The VHF path goes to the
Downlink Input of VHF Amplifier Shelf 80-301409 and the UHF Lowband path goes to the Downlink
Input of UHF Lowband Amplifier Shelf 80-301410.
The UHF Mid and Highband paths leave Downlink Input Shelf 80-301407 the UHF Midband path goes
to the Downlink Input of UHF Midband Amplifier Shelf 80-301410; the UHF Highband path goes to the
Downlink Input of UHF Highband Amplifier Shelf 80-301410
The 800MHz path leaves Downlink Input Shelf 80-301407 and goes to the Downlink Input of 800MHz
Amplifier Shelf 80-301411
After their respective amplification stages the signal paths enter Downlink Output Shelf 80-301408
where they are combined into a single path and fed into the radiating cable.
Uplink
The Uplink signal signal is received from the radiating cable and enters Uplink Input Shelf 80-301407
where by means of crossband splitter/couplers it is split into VHF, UHF and 800MHz paths, the UHF
path is further split into Low, Middle and High band paths.
The VHF and UHF LowBand paths leave Uplink Input Shelf 80-301407. The VHF path goes to the
Uplink Input of VHF Amplifier Shelf 80-301409 and the UHF Lowband path goes to the Uplink Input of
UHF Lowband Amplifier Shelf 80-301410.
The UHF Mid and Highband paths leave Uplink Input Shelf 80-301407 the UHF Midband path goes to
the Uplink Input of UHF Midband Amplifier Shelf 80-301410; the UHF Highband path goes to the
Uplink Input of UHF Highband Amplifier Shelf 80-301410
The 800MHz path leaves Uplink Input Shelf 80-301407 and goes to the Uplinklink Input of 800MHz
Amplifier Shelf 80-301411
After their respective amplification stages the signal paths enter Uplink Output Shelf 80-301407 where
they are combined into a single path and fed into the radiating cable.
