I understand that. I presently have a huge 17db gain parabolic UHF antenna 28 ft. in the air with a mast mounted preamp and RG-11 cable, but would gladly replace it with a circularly polarized type and add a rotor if it meant I could at last get 'broadcast quality' ATSC reception. My question remains unanswered. How much testing has ever been done on ATSC rception using circular polarization? How well does it actually work compared to the sputtering, freezing, choppy ATSC 'reception' I now endure? > To get the anti-ghosting benefit, you would >have to have an outdoor antenna that was mounted on a mast and rotor. >(Being a CP antenna, it is also by definition directional.) Fine,I'm certainly willing to do all that. I just expect it to work far better than what I have now. See pic.
