[TowerTalk] Installation Rohn 25G

[D. Scott MacKenzie]

Bracketing makes all the difference in the world.  Looking at the Rohn
catalog, it makes a huge difference in the load carrying capacity whether
they are freestanding or bracketed.  Your results do not surprise me at
all....

Look at the following link.

http://www.n4zkf.com/shack.htm

Scroll to the bottom. The two towers you see. Both are 40' Rohn 25 "not
guyed".
1 has a A3S tribander, a 12 el 2 meter SSB AND a 24 el 440 SSB antenna on
it.

The other has a 6 Meter beam, stacked 2 meter beams and an omni.

Now, they are tied at 10' with a house bracket on the roof. But they are
NOT GUYED. Google earth my QTH and you will see I live 1000' off the ocean
beachside, saw
3 hurricanes in as many weeks come right over top of me a few years ago and
they
are both standing. What can I say.

Just for a bit of clarification:
After reading the previous postes I'm a little confused. How high are you
going before you put up the antennas and guys?
That size base isn't suficient to hold a 40 foot 25G and tribander without
guys except on a very calm day. I'd also be apprehensive about climbing 40 a
foot 25G without guys even on a calm day.

Fortunately 40 feet and a small tribander don't take an elaborate base and
guy system which becomes much more substantial in a hurry as you add height.

I have a rather simple and effective, but heavy gin pole I constructed.  If
I can find everything I'll try and  shoot some photos and put them up on my
site.

Good Luck and be careful.
