The best approach is two antennas with plus 1 wavelength between them into two separate receivers and switch the audio between them based on a decision circuit looking at both radios AGC voltage. -- Telamon Ventura, California http://www.radioblvd.com/DiversityDD1.html I find the: "At first the engineers speculated that radio waves were being refracted in the ionosphere at different angles and therefore some waves would be intercepted by an antenna while other wave-angles would miss the antenna. A large multiple antenna should capture more wave angles and reduce fading. Actually, they found the opposite happened. Fading became worse with larger antenna arrays. " to agree with my experience in the much shorter active dipoles (~3' per leg) worked much better then the 50' wire antennas. Terry |
