On May 21 a storm took down my 100' Rohn 25G. All the "big grip" connections, EHS cable, etc held up ok. When an 80' tall tree fell on the SE guy wires, the NW guy anchor pulled up out of the ground,
Mick: A possible fix depending on how you are at welding or know someone who is a certified welder is to trim the legs down to say 12" long vertically. Weld some channel legs to the stub legs say 8"
WARNING: Welding on tower legs is welding on galvanized material. This gives off a very poisonous gas. Make sure the wind blows the smoke away from whoever does the welding. I'd do it the way they do

My suggestion would be to flush cut the remaining legs with the surface of the concrete base. Then drill a hole in the center of the concrete base for a pier pin instead, provided they make a pier pi

K1KW suggested: When my 100-footer fell some years back (trees on the guy wires), I did what K1KW said, except that I left the 6-inch long bent and broken stubs of the old base section in place. I bu
I cut the 'bloody stub' off flush with the base, grouted the old legs shut and bought the Rohn 25GSSB base. Drilled 4 holes and installed 'L' bolts as large as would fit the holes in the plate. Think
And the fourth reason is that 25G leg wall is really THIN. I don't think they're thick enough to weld too without putting a hole in the material. You can't Cadweld them either. Cheers, Steve K7LXC TO
Ugh - I don't care for pier pins because of the time and effort needed to secure the temporary guys. I'm doing a job right now with the same circumstances (tree fell on guys and pulled the top of the
