Mel:
Another suggestion a commercial tower person gave me years ago when I was
putting
up 40 ft of Rohn 25 was to put in a six inch to 1 foot or so layer of gravel at
the bottom of the hole then press the base or bottom tower section into the
gravel slightly and moisture in the legs would then drain through the gravel
into
the dirt below. I tried it with the Rohn 25 I put up and never had any moisture
problems, even when I took the tower down several years later when I was moving
to a new QTH. I've since bought a 50 ft Tri Ex crank up that has a slightly
bent, but still "open" bottom on each of the 3 "legs" of each tower crank up
section.
