I believe K2TTT put one tower up using nothing as a base, just the tower standing on a small plate, resting directly on ground. Yes, it is (was) guyed. Dave, am I correct? Hans - N2JFS Why use Rebar

If I understand you right, the screw anchors should be replaced at about ten years interval. Needless to say, if something fails due to corrosion or what-have-you it will break, that's what maintenan

I understand that. I think that if replacing the screw anchors every 10 years could prevent such a disaster I don't see that as a big problem. Not replacing them take a chance, well... . No, I will n

Patrick, It is very obvious that if we can keep moister out, no corrosion will take place, that's valid for almost all applications. The problem is that RTV application is not a long term solution. I
