And one of the big problems with such antennas for contest use is that the 3 degree bandwidth is too narrow for optimum coverage in Europe, where you need to "bathe" as many potential contacts with a
Curtain arrays are available in many shapes and sizes. The 21DBi gain model is just one example (as a comparison with the super long yagi). They are basically a bunch of stacked (vertically and horiz
Yes, and 21+ dB (including ground reflection) is hard to come by any other way. I was thinking more in terms of a contester making the choice between, say, 16 dBi from a long-boom yagi versus the sam
TT: But remember: These antennas are sized in terms of ACRES of area, not square feet! Check out: http://www.antenna.be/hr.html . 73 de Gene Smar AD3F These arrays can also slew the beam as much as +
Yes, of course, but we are talking about fancy set-ups that have no concerns about real estate. Not exactly your average suburban lot! -Zyg- AF4MP -- Zyg AF4MP Roswell GA USA
The rotatable curtain antenna (refer to URL below) is exactly what is needed! http://www.antenna.be/rhr.html No serious contester should be without one. -Zyg- AF4MP
Pete, I don't think you can have it both ways. If they are the same gain and one has a wider azimuth beam width it must have a narrower elevation beam width. That gain (power) has to come from somew
Yes, agreed, but the stack has a wider elevation coverage in the sense that you can quickly change configuration (U/L/BIP/BOP). With the single long boom yagi, you can only adjust azimuth, the elevat
I understand the point you're making -- the old water balloon analogy -- some fussy detail about the conservation of energy...hi But doesn't it come out of higher-angle secondary forward lobes? That
