That is some scary video. That is something I would not want to do...
The height of that Mast is incredible when compared to, say, taking a flying lesson. At Biggin Hill (Kent UK) flying sessions are at approx 2000 feet. That climber going to the top of the mast is short of that height, but not that far off. Try a flying lesson in a two seater cessna at 2k ft and being buffeted by the winds - OMG!!! I really, really do appreciate what the climber is being exposed to up there, I don't wish for any lessons on that.
The video is an extreme case, but it is not uncommon for CSA in civil cases to require climbing up a mast, eg where defective TRXs affecting coverage are insitu. Consideration is needed whether the defect is caused by faulty TRX/s or its/their installation affecting coverage service, to determine the commercial impact of the affected service by the defect.
