Hi Everyone, I know this is an old thread, but I am looking at towers, and am particularly impressed with the Trylon STG towers as well. They appear to be way stronger than the Rohn 65G, and they sel

Thanks Steve, That explains a thing that was really bothering me on the 45G specs. I saw so many people putting much more than the specs allowed, and getting away with it for decades. It seems intuit
