We bought a house that has a massive ham radio antenna in the back yard. I believe the radio room that connected to the tower was destroyed in a fire. The tower is about 120-150’ tall, galvanized steel monopole with aluminum cross members, on a rotating mechanized base, attached to a concrete block 8’x8’ in cross section, 13.5’ above ground level. Supposedly has 3-phase power run to it, but don’t know where it is. The main tower pole is polygonal and probably 15” in diameter at the bottom. No paint or lights on it. Any help figuring out make, model, construction specs, etc, would be greatly appreciated.
