I did 10 years of Ground Radio Maintenance in the Air Force. Notice the word "Ground" About the scariest place I had to go was on the cat walk of the Air Traffic Control Tower!! I don't know how you guys do it...and I commend you for it!! I see you're doing it with safety gear:)
We took care of the all the radio equipment from the handset/headset through to the antenna jack. Antenna Maintenance took it from there!
