Of course the best of both worlds is to have a crossed yagi with a phase switching box so that you can select CP (both hands) H, V or slant 45 both ways. Jeff, I want the" best of both" worlds but before one jumps one needs to know the advantages and disadvantages of both first. To be frank, I do not know what happens to all signals when they are reflected including the reflection off the ground to a receiver or a direct hit on the receiver from our upper layers so I have no way of undertaking a comparison. Now most hams are resistant to change or will only follow the majoratory thus the questions "who has the majoratory". For me I see CP as an ideal approach for smaller volume antennas which is the "holy grail" for hams, but one has to determine if smaller is important enough to overide possible faults.Now I have a whip antenna ( no ground plane) on my tower that is CP for top band but the bands are poor it is difficult to determine its worth especially since there are no similar radiators out there. So I fall back and ask for "what is known already" as there is no point in re inventing the wheel. Is that so bad? Now before the catwalling about the possibility of having a whip (a 5 foot pole) for top band my intention is to release all that during the next month. So lets not waste energy in side tracking comments and stay on the essence of this thread. Remember the last time I intended to release it was evident that most did not want to hear it........ so I went along ! Commercially (terrestrially) I don't think that CP is used much except perhaps on microwave point to point links. Jeff |
