Thanks everyone for the Fast answer. I thought it was adjustable, I have Heard if You Sink a Tower in the Ground 4-8 Ft With rebar and Pour the Concrete If Lighting Strikes the Tower it Can Explode in the Concrete even if You do put out Ground Wires at the Base. And the Tower will corrode Faster and the Galva -ionization will be ate away. Have No Idea if that’s True But That what I wish to do., At 60 If it Last 10 Yrs I will be Happy .
Thanks Don KA9QJG
