I use 3 anchors, 6" thread, 5 foot shaft, to hold up a 100' Rohn 25G =
tower, with 3 sets of =BC" EHS guys, broken with insulators. The =
anchors are in sand. Tower has taken gusts of 58mph (maybe more) to =
date, and is still as solid as the day I put it up. I don't have turn =
buckles in-line--just grips and tension by feel and eyeball.
A power company guy told me these would be pretty good--you can use them =
for anchors to winch your truck out. They has some 6 footers with 1 =
foot thread that a D6 Cat could not pull out of a swamp.
Cars hit the guys all the time and only pull the bolt and washer through =
the top of the pole. The power guys simply drill another hole and put =
the bolt back in.
Depending on your soil--these work well. Some of the big 200' cable =
towers around here (SW MI) are held up with these, as well as most ham =
towers, including some 180' private repeater towers.=20
