WSBTV Antennae replacement Atlanta
Happened this week.
Always admire the accuracy needed in contracts like this, and admire the guys with big balls to climb 900ft to unbolt the old and then guide the new antenna into place. Here is the news clip I found, pretty sure others may have better film of the operation.

Just to clarify the above, as G-BFPF this helicopter was with British Airways Helicopters from 1978 until July 81 when as British Caledonian Helicopters we operated it until Bristow took us over in November 1987. The ownership of all the ex-British Caledonian machines was then re-registered to Caledonian Helicopters at Redhill - to all intents and purposes they were Bristow machines. Until they were repainted in Bristow colours they were operated with the word "British" merely painted over. In early 1989 PF left the UK for Court Helicopters in South Africa. Good to see her still operational as a short 61.

What Guide Wires, They may have had a short alignment pin at the top but there are no guide wires used in this process as the risk to the tower crew would be to high to be acceptable.

This will also help stabilize the load from starting to swing when being lowered into place, as it acts like an anchor, and is making the job for the pilot a lot easier. You can see this from the gopro video how the antenna is offset to target, then it slides sideways in, then twists ("the pilot" align the holes
) as the antenna makes contact.Bksmithca,

If you know this type of work and look for details as someone doing this type work, you see it quite easily.
