I need your expertise
I am planning the rotor setup for OB4-40 (coil loaded 40m 4el yagi)
OB4-40 has wind load at 130 km/h = 1.200 N / 1,49 m² / 16,2 feet²/
There will be mast bearings help to minimize vertical load and bending moment from an antenna to rotator.
I like to use The BIG BOY model PST2051 .
PST2051 is rated @ 23.4 sq. ft. - wind load area (sq. ft.). (2.5m2)
What is your experience with this rotor ???
