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.
