I have 120 ft of Rohn 25 in a dense redwood forest. Bottom section is 4 
ft into the concrete base; guying is at 30, 60, 90, and 120 ft, each guy 
to the base a different tree (12 different trees). It holds the straight 
3-el SteppIR, a 6M7LFA, the feedpoint of a 40M wire yagi fixed on EU, 
and a pair of wires that each form a sloping vertical for 160M.
