make a nice radial now) & I have a new

I have much choice which direction to put
it back up, but I have a couple options.

Thanks Clive! I did a F/B test towards the TX ant and the F/B is indeed
5 db less. I may need to think of that solution.

Ash, at less than 1 wavelength the TX antenna is still within the
near field and can most certainly impact the receiving array. The
real questions are how much does it impact the shortened verticals
(pattern impact) and how much noise does it
I sent this to the members of our local radio club as I'm trying to get
them to understand the importance of SR and SS on 80 and 160M; I thought
some of you may enjoy it. March is here and conditions should be
improving for NA to VK/ZL contacts I hope this morning is a good sign..

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

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

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
