wrote: Hi, Well, our Super J-pole: http://users.marktwain.net/aschmitz/...jpolecalc.html Is beating our Yagi in ALL directions, even in the forward lobe! much snippage Must be one horridly poor yagi. Most 3 eleemnt designs are better than 8dBi and with a little effort an be 1 db better than that. 8 dBi WITH a 180 degree pattern? And WITH A F/B ratio that doesn't exceed 11 dB or so? I don't think so. Do you have a design you can show us? Most Stacked Jpoles do not perform as well as predicted on paper with the upper added dipole contributing .5 to 1 db less than guessed at. Allison How did you come to this conclusion? What sort of field strength equipment did you use? Again, i would be the first to say that reality doesn't fit the math model, sometimes not at all. But is this case, you can really hear the difference. Slick Slick |
