[TowerTalk] Rohn 25 and relatively large Tribanders

[Ed Swiderski, KU4BP]

Very interesting subject. I am planning 70 feet of Rohn 25 with a Force 12
C4XL turned by an old Ham-2 rotor. Been utlizing the Rohn specs in their
book and according to them I should be fine here in central NC. The tower
was one my friend had up at his place that we to down last week. He had two
4-el 15m monos on it.

Progress with it is slow until I get back to work but I got the sections
over here last week and the antenna is halfway assembled. My next project on
it is to get the base and anchors dug and poured.

Received my copy of "Up The Tower" today so that will be a big help the
projected completed.

No matter if you are doing the work yourself or hiring professional help I
think that having the manufacturer's data and specs available is simply a
'must have' for a good tower project. There's too much at risk in terms of
potential damage to property and life to not know what the manufacturer
recommends for an installation of the tower model, height, etc.

I know there are some very knowledgeable amateurs and professionals here but
I cringe anytime I read a message where someone says "I'm going to put up xx
tower at a certain height. Do you think I should guy it? Do I really need
all that concrete? ...etc."

My $0.02
