Ash,
model it when the RX antenna is pointing at the TX antenna. There is a good
chance it will affect the pattern, but lifting the base of the TX antenna above
ground with a relay when on RX will cure that. 73 Clive GM3POI

Clive,
The vertical is 130m away from the array center. I'm presuming this is a
good distance to avoid interaction.

Ash model in also your TX antenna and see whether you need to isolate that
vertical on RX with a relay. 73 Clive GM3POI

Hi guys,
I built a 4 Square Receiving Array for 160m at 3V8SF. I put details in
my website: http://kf5eyy.info/topband.htm
The achieved F/B so far is 20 db and the F/S is 19 db. There is still
room for improvement with better matching of the elements. I'll need
time to do that.
Thanks to Ahmad 3V1B and Majdi 3V1M for helping me setting up of the
elements. Also to K7TJR, W3LPL and W0FLS
for the valuable support.
