General Notes
1. The antenna and radome are in good condition. The radome was clean with no damage
and no visible leaks. The caulking between radome panels is in good condition. No repair
or maintenance required at this time.
2. The electrical power inverters were originally mounted on the antenna pedestal frame
directly above the air conditioner. They have since been moved to the floor of the radome
which eliminates the chance of the antenna reflector being damaged by making contact
with the corners of the inverter’s mounting plates.
