Topband: RX 4 squares

[Larry Molitor]

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.

>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. Does anyone have any experience with RX 4 squares near or surrounding non-resonant towers?
