Norm's Rotor Service is an excellent choice. I've known Norm for over 25 years, had HyGain rotors of my own serviced there. Fine job, reasonable prices. I am not affilliated with Norm in any way. Bil

Dale, It is not a Bozo idea at all!! At the top of my 134 foot tower, I run the coax for the 10M Beam, 40M beam and 80 M rotatable dipole inside the 18 ft mast, out the top of the mast, and attach th
I should add that the mast is held in place in the center of the tower by two ROHN TB-3 thrust bearings, separated 30 inches apart and mounted on plates inside the tower. There is no conventional rot
