Hi Mike,
I think Tom, N4KG mentioned this in his comments.
The Rohn HW tower sections are just 25G tubes with a wider face and
larger bracing. This makes the sections stiffer than the 25G.
The Rohn data sheet I have actually lists lower base compression and leg
compression values than they do for the 25G (old catalogue). Don't know
why....
You can call Rohn.Cellular Products, 309-697-4400 and ask them to fax
you the "HW" sheet.
Definitely, treat it like 25G, not 45G.
Don't know what it goes for, got mine free (?) for taking it down. I'd
put it just a bit more than the used 25G market.
It's nice stuff if in good shape. If deciding between 25G or HW, get the
HW. If you are deciding between HW or 45G, get 45G. I have all three.
The HW will easily accomodate a small prop pitch, if one is willing to
fabricate a removable bolt in diagonal to get it in the tower.
