Forget the guy wire complications. Tram to a higher spot, say 70' nominally,
then it is relatively trivial to drop the antenna into place.
73, Dan
I am hoisting JK Mid Tri (100 lb) to 65' on a 100' 45G. There are 3 sets of
guy wires at 32', 62' and 95'. I am not clearing one guy at 62'. If I
remove that guy wire, should I loosen the other guy wires at 62', to avoid
potential bending?

That is a great idea Jon, easier than my waiting for the concrete to
partially set method and hoping that the pin does not sink.

The Rohn spec is to leave 4" exposed.
I use a U-bolt to clamp the rod to a piece of aluminum or steel angle that I
place diagonally across the form, checking measurement on the other diagonal
to make sure it is centered. I place this shortly after concrete is poured.

I am hoisting JK Mid Tri (100 lb) to 65' on a 100' 45G. There are 3 sets of
guy wires at 32', 62' and 95'. I am not clearing one guy at 62'. If I
remove that guy wire, should I loosen the other guy wires at 62', to avoid
potential bending?

I do not loosen the opposing guys on my Rohn 55 and Rohn 65 when dropping
one for antenna installation however I am not a tower engineer and cannot
recommend that anyone else do this.

I would advise against loosening the other guy wires.
What I would suggest you consider is what I have done at my qth:
1) Prepare a temporary guy of the same approximate length as the
permanent guy.
2) Measure the tension of the existing guy wires to ensure that they are
correct.
3) Before removing the guy wire at 62', hoist up the antenna to just
below the guy wire that you want to loosen and tightly secure the
antenna horizontally from both the boom and mast to the tower.
4) Pull up the temporary guy wire, attach it to the tower about two
tower rungs below the existing guy wire at 62' and then tighten it to
approximately the same tension as the existing guy wire and measure the
tension with a Loos gauge or similar instrument to confirm.
5) Loosen the permanent guy wire - then carefully detach it and
temporarily attach it about one rung below the temporary guy wire.
6) Hoist the antenna and permanently mount it properly.
7) Pull up and reattach the permanent guy in its usual place and
properly tension it - measure the tension with the Loos gauge.
8) Loosen and detach the temporary guy wire and lower it down and remove
it from the tower.
You're done! Slowly, and safely.
I have used this method successfully several times at my qth. Others
may have different preferred methods of doing the same thing. Whatever
you decide to do, please remember to NEVER compromise safety for speed.
73 and GL!
