That video brings back memories and makes my palms sweat. Around 1970/71 I helped remove a transmission line from the Fort Dodge, IA, KVFD tower that was located in Fort Dodge. I don't think this tower was much over 400' or so.
I replaced some of the tower lamps on the Bradgate, IA, KVFD, channel 21 tower. This tower is 1200' high. I noticed that after about 400' or 500', it didn't make any difference how high the tower was, as the view of the ground remained the same. I used a safety belt with scare strap. I would only work on and stay within the tower structure and not the antenna. The antenna was 80' high and out in the open. That was outside my comfort zone.
I built lots of 60' Rohn towers and worked on other small towers, like 120' self supporting ones. The self supporting towers would sway a lot in the wind. Which was a fun ride while working with the tower movement.
