wrote: I don't operate on 40 M so I may be missing something but exactly what is it that stands out with this antenna that would make it desirable to hams? From the title: "Two-Element Driven Array *With Improved Tuning and Matching* (emphasis added)" The major claim is that the antenna is more easily adjusted than the alternatives. This would seem to make it "desirable." Efficiency would be reflected by the loads used which is not necessarily "state of the art". What "loads"? He then states "a large F/B is effected" but it doesn't show before and after overlaid plots ! He doesn't claim "improved" F/B, only "comparable to that which is available from a three element Yagi of similar electromagnetic properties." So what before and after do you expect to see? Would hams have an interest in a two element 20 M antenna that have lower TOA than the norm, say 9 degrees instead of the normal 14 degrees? Yeah, I'm still interested in seeing how you can lower the "TOA" without changing the antenna height, or is that the "secret"? |
