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. 73 de YO3FFF Cristi =============================================== Here is a link to the NCJ article describing the loop: http://www.n6rk.com/loopantennas/NCJ_loop_antenna_N6RK.pdf Rick N6RK _______________________________________________ Stew Perry Topband Distance Challenge coming on December 29th. _______________________________________________ Stew Perry Topband Distance Challenge coming on December 29th.
