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 noise
to the WF.
Take a look at my YouTube video entitled: "N8PR TX Antenna Construction and
Detuning effects on receive Noise"
https://www.youtube.com/watch?v=sk6PVl7uaBM&t=257s
I think that you will see that the detuning is worthwhile.

1. Location of WF RX Antenna. Need Expert Advice
{{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 midway
(150' separation) between two existing LM-470 towers now separated by
about 300'. One has a 4-element Steppir and a 13-element 2M yagi on it
and the other a 2 element 30/40M quad. Obviously, the WF would not be
used simultaneously as the two existing antennas, and the Heights tower
would be well grounded.. Am I asking for a round of battles of trying
to mitigate interaction problems on either TX or RX on any of the bands
involved? Would an easy answer to my question be obtained from an EZNEC
simulation, especially since I already have models of the two current
antennas?
I suspect other people on this reflector have been here before. I'd
appreciate any practical advice.
Many thanks and 73,
Joe
