I'm in the process of putting up my tower (after a 6.5 year wait). Last night, I obtained a 2" Al mast and fitted it in my 25AG3 top section. I'm concerned that the fit is rather snug, and might caus
OM, Here is the setup I used. Had a 60' tower with the TH7DX right at the apex of the "pointy piece" with an 1/4" wall thickness aluminum mast up from it holding a variety of other antennae. To "stif
