Notes:
A single 110 VAC surge suppressor protects the whole rack.
The RF Amp has its own 110 VAC power supply.
Everything else runs off a single 10-16 VDC, battery-backed power supply/charger.
The controller in the power amp chassis runs off the 10-16 VDC (not the 110 VAC).
This power supply architecture avoids the need for a battery-backed AC inverter.
Both antennas need lightening/EMP protection.
The various comms connections need appropriate protection.
Connections within chassis are not shown.
The power supply/charger may have status that needs to be connected to the PC.
