Re: Topband: Location of WF RX Antenna. Need Expert Advice

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 modify its pattern. Low gain loops, such as the Waller flag, are more critical compared to beverage

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 affected by tall vertical thingies in the area; and less prone to local noise in the area which

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 well as the transmit antenna while using the WF on receive to eliminate them re-radiating noi
