Re: [AFMUG] freestanding 25g max height
We pretty much guy all of our 25G towers above 20'. Those crazy heights without guys do not really account for the amount of wind load that we generally put on them. I know they are wobbly as hell at 30' without guys.

Re: [AFMUG] freestanding 25g max height
It's going to depend a lot on the wind load. If the load is light, I would go with 2 10' sections above the last brace or guy. If the load is heavy, only one.

Re: [AFMUG] freestanding 25g max height
I climb them with no issues... I trust the physics after we brought one down which had one split leg from ice/water damage... We tied safety ropes to it, used a backhoe tractor and brought shovel up to about 15 feet. Chained it and then cut two legs with saw saw.. We eased it down... We cut third leg half way and had to muscle it to come down... Even at angle it supported itself without dropping to ground! We had to cut remainding end So unless tower is in bad shape... It should be solid.

Re: [AFMUG] freestanding 25g max height
I'm taking down a 70' 25g that is bracketed at 20' and has a 10' pipe in the top. I took the territory over on trade with another WISP. It has been there for 18 months approx and has had 70mph storms that took down trees since I took it over. I didn't sleep that night but it still stands. It sucks to climb and we are replacing it with a 80' guyed tower in the guys yard.
