Terry, with the assistance and skill of the legendary Skip, KJ6Y, I have just had installed the US Tower MA-40, and cannot recommend it more highly especially for a tight urban lot. The tubular tower easily supports a 63-pound SteppIR DB-11 plus a smaller 40M rotatable MFJ dipole. It rests when I’m not operating at the roof level, and rises to well above roof line (2 story house) fully extended. This is a mighty little tower. Happy to round up some still shots for you off-list if you wish.
