As I build up the VHF antennas I have at present a Rohn 25 at 55 feet,
guyed at 30 feet with torsion bars and guy bracket, Plans were to also guy
at 50 feet with the same setup, guy bracket, torsion bars. But they are on
the ground as that was the next step on the tower to finish. Well, After 5
months of watching this tower go up section by section as I got my nerve
and had friends help get all of it up., I've come to realize I do NOT do
towers very well. At 30 feet I get the jitters, I don't need to be playing
at 50+ feet with antennas. Soooo.
I just ordered a Hazer to get past this problem. They recommend just guying
at the top a few inches above the hazers top resting stop. Rohn says to
guy at around 30 feet and 50 feet with two sets of guys. So do I trust the
hazer set up at 55 feet with guys only at the top so it can travel downward
when needed ?
Planned antennas are a Cushcraft A4S just above the top on a 16 foot 2" OD
mast with 2 each M2 12 ele 144 mhz beams ( 19 foot booms ). One mounted at
the top of the mast and one 11 feet down. (stacked for 2 meters).
Or do I need to take about 10 feet off the top and play it safe. I do have
another 30 foot tower I could move 10 feet over on that I use for various
VHF antennas that is guyed and house bracketed. A array of DX-120 beams go
here.
Numerous antennas 4 Cushcraft DX-120s in an array ( 80- elems) also the
same set up for 432. A couple of M2 12 ele, 19 foot booms ready to be
stacked. Cushcraft A4S tri-bander so when 2 meters and 432 isn't open. and
a vertical for 2 meters,. Im not antenna poor I guess. Just not sure what's
the best way to arrange them on the towers.
