I am hoping to construct a Waller Flag RX antenna on a 56' Heights aluminum tower for 80 and 160M RX. The ideal location from aesthetic, RF and maintenance-of-a-civil -family-climate standpoints is m
Joe, You might consider that there is interaction of the Waller Flag and the other two towers as well as your transmit antenna while on receive. I suggest that you detune both of the other towers, as
Interesting. My rcv array is probably 500 ft from the Xmit antenna or any antenna so I am probably ok? My 70ft tower is 70ish feet from the 160 inverted l. I wonder if there is much to be gained b
W0MU 500 feet is only 1 wavelength on top band. Interaction is entirely possible at that distance. Two verticals spaced 1/2 wavelength is a commonly used directional array design. Rick N6RK _________
I've just recently been reading up on Waller Flags, and am certainly no expert, but my impression so far is that an HWF (horizontally polarized flag), mounted up in the air on a tower, should be less
It depends not only on distance. Also the gain of both (TX- and RX) antennas matters. The lower the gain of the RX antenna, the more the re-radiating TX antenna (or other nearby wires/towers) will mo

Steve, yes, you're the second person to mention that characteristic. Although it makes sense now that you mention it, I really didn't appreciate that difference. I suspect that the detuning step woul
