These difficulties have long been solved in the world of radar, so, has anyone conceived of an infinitely rotatable 50 ohm coupling for our beam antennae? Clearly there would have to be some mechanical support other than just the co-axial coupling to withstand the wind storms that we are all now experiencing?
