Bob, My Hi-Z 4-square was only 80 feet from my 160 TX vertical (which is disconnected with relays during RX periods and non-resonant). The other towers, also non-resonant, were about a half wave away. Although there was noticeable pattern distortion, the array was still very effective.
In my experience, you would probably have more trouble with the resonant antennas a half wave away then the nearby non-resonant antennas/towers. I suggest that you use relays to make the resonant structures become non-resonant during RX periods. Of course, ALL RX antennas will have greatly diminished performance in the presence of resonant structures including elevated radials. 73, Larry - W7IUV >________________________________ > From: Bob Kupps <[email protected]> >To: topband <[email protected]> >Sent: Thursday, August 9, 2012 4:41 AM >Subject: Topband: RX 4 squares > >Hi I would like to put up a RX 4 square array for 80/160 but the only place >(just) over a half wave away from resonant verticals on those bands would be >surrounding (15m out from) a 70' tower with 2 large yagis on top.
