4.8. Uplink Output Shelf 80-301407
Uplink Output Shelf 80-301407 is part of the main Splitter/Combiner assembly. Signals are received
from the various amplification stages and then combined into a single signal which is output to the
leaky feeder. The unit is housed in a 4U, 19” rack mount case which is mounted in Rack 1.
Ports labelled 6 to 10 (Annotated A to E in section 4.8.4.1.) are the Uplink inputs from the
amplification stages.
The Uplink signal leaves the Uplink Output Shelf 80-301407 for the leakey feeder via the port labelled
“UPLINK OUTPUT” (F in section 4.8.4.1.) and there is a 30dB test port labelled “UPLINK OUTPUT
TEST PORT” (G in section 4.8.4.1.).
