[Antennaware] K9AY RxLoop with 2 turn loop (160m)

[OZ1AXG Flam]

Hi Experts!

I read on the internet that adding "turns" to the Loop could improve signal 
strength ?

Question: how much would signal improve adding one extra turn (n=2)  versus 
single loop (n=1) ?

The loop im currently deployed has loop size = 28 meters and is pretty much 
standard dimentions...

Adding another 28 meter could me be a mechanical challenge since the two 
wire would bounce around when windy ... how would this impact performance ?
