[VHFcontesting] Guying a Rohn Tower

[Bob Naumann - W5OV]

John,

With a house bracket ( why two? ) the height you are planning is just fine.
Rohn 25 is extremely strong stuff.

With a good base (4' deep x 2'x 2') you can safely use it completely free
standing up to 30' or so.

With 45 you would have no risk at all.

73,
Bob W5OV (ex N5NJ)

P.S.  That 719B is a great antenna.

P.P.S.  I'd go with a 3 ele tribander unless you're talking about an F12 C3.

Subject: [VHFcontesting] Guying a Rohn Tower

I am in the planning stages for getting a tower up in the next couple of
years (hopefully) and am hoping to get some feedback from the group
concerning this.  Here is my situation:  I don't have much room for guy
wires in my yard, nor a desire to have guys running all over my yard.  I
wonder if I could go with Rohn 25 or 45 unguyed, as I could use house
brackets on 2 sides to help support it.  I would like to have 40 feet or so
of tower, with a 2 element tribander (16 pounds), a cushcraft 13B2 (5
pounds), and a Cushcraft 719B (3 pounds) mounted on the mast-whatever that
weights.  Is this a reasonable setup, or would Rohn 25 or 45 have to be
guyed, even with the house brackets?

Or any other suggests for an unguyed tower or mast?  Trying to keep the cost
down a little also.

73s John NE0P
