Topband: 4SQ Arrays in proximity

[W7RH]

While I can not speak directly of 4 sq interaction, I'll add my comments 
on antenna interaction. I have  an all vertical antenna farm if you will 
with 17 verticals covering 160-HF.

In my case I have 3 elements interlaced with separate feed on 80m within 
my 5 element 160m antenna which beams broadside end-fire in East/West 
and Endfire NE,SE,SW and NW. I have not seen any degradation of either 
array.  You might picture it as being just like a vertical Yagi in 
end-fire configuration.

I also have a full sized 8 circle on 40m with an old HighGain high tower 
junior in the middle for HF Omni operation. In that case I do de-tune 
via switched in inductance at the base of the Omni when not in use to 
make sure there is very little if any coupling into the 8 circle array. 
Again, I don't see any performance degradation.

If you have the space go for separation, if not there are simple 
alternatives that have low impact on overall performance.
