Hi John and Dan,
Tram's are useful and preferred and I have used them wherever possible;
however, in heavily forested areas away from paved roads or driveways,
and especially with ledge and highly uneven terrain, there may not be
the clearance to tram up antennas beyond a certain height, if at all.
In those instances, alternative methods, like removing a guy wire, may
be the only way possible to get an antenna up the tower, and, if it can
be done properly, there is no reason to avoid it. Which is why I had to
do that at my qth for one of my towers.
Years later after removing more trees and having a few hurricanes and
tornados remove additional trees for me ;-) now all antennas can be
trammed up at my qth.

I previously responded to the guy wire removal part of the question but

is right about traming higher to clear the guy. It can even be done
without
a tram and without removing guys. I have installed many large antennas
in
the middle of a tower by having the pull rope pulley near the top of
the
tower and just pulling the antenna away around the guys as it is
raised.

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?
