I bought and had installed a wooden utility pole (65 feet) and hired a crane to install a bracket and pulley for a dipole and mounted a mast and rotor for the Yagi. No permits needed for utility poles, BUT GUESS what??
When the DAM antenna has a problem I have to hire a crane truck @ $500/4 hrs to drive over my lawn........(wait for a dry spell before dong this) and fix the antenna. My luck has been the Cushcraft A3S is not serving me well at all. Totally useless!!
The dipole is very happy at 65 feet and full length for 160M. I would be embarrassed to give the cost of the pole and install. Probably cudda had a 60 footer at half the price......I'm not too smart sometimes.
My (local city) electric utility folks will put in a 35 ft pole for $100, no permit needed.
