I’m an old tower climber as well. The IF can be disrupted like no-bodys tomorrow.
Cool! Never cared much for heights myself. Seems like I get something akin vertigo when I get very more than about 15 - 20 feet off the ground. BTW, I’m sure you’ve seen the pic of the guys working on the antenna on top of the Empire State Building — camera aimed DOWN on them! I get the willies just looking at the pic!
