3.9.1 Description
The 40Watt master site power amplifier shelf concerns itself with powering the 800MHz channel
information to the LCX tunnel antennas. The output from the channel module shelves is split into two
and input to each of the two PA shelves. Each PA powers either the East or West tunnel leaky feeder
antennas and a proportion of the LCX signal provides a feed to the 800MHz in-line amplifiers that
power the fire exit stairs antennas. All amplifiers in the shelf have alarms and they terminate at the
rear panel mounted 9-way ‘D’ connector, pins 1 & 2.
Since the Mission Valley system was first commissioned, the upgrade was designed and built using a
high power shelf (50-078005) instead of the 40Watt shelf described here. Therefore, this section is
shown for information only.
