Hello Rick,
I've tried also a K9AY such loop on the past SP contest and was a good
improvement over my INV-L. I never heard before CE1/K7CA and south american DX
stations. An A/B test were "all to nothing" for K9AY loop comparing with INV-L
for many times.
Due to local constraint, I'm using a single loop on E-W switchable
configuration. The F/B is about 15 to 25dB measured on MW BC band.
Despite it is mounted on the INV-L near field (about 25 meters away), the
mutual coupling does not damage too much the radiation pattern.
I suggest to everyone who does not try a receiving antenna on 160m to give it a
try. It will make a BIG difference.
