Guy, Thanks for the links to the articles. I remember seeing John's article a while back before I tried any "advanced" antennas, and I was glad to be reminded of it. Mark's article has a lot to digest! I've been trying to do some testing of my small Superloop, but it's a lot more challenging than I had realized. In some preliminary daytime testing at home where my angles are limited, I couldn't get a front-to-back ratio better than about 15 dB, although the 10 dB range seemed to be pretty broad on the termination side. I suspect this has been working well at night for me due to a more optimal reception angle, and especially because I can work so many frequencies at once as compared to my tuned antennas. Sometime in the next few weeks I'm planning on setting up in an open field and doing a full 360 degree set of measurements to test out the pattern and resistor settings.
(BTW, you and Gary and others may be interested to hear that I made an impulse buy of a Tecsun PL-380, which should arrive tomorrow. I don't know whether I'll do any antenna hot-rodding on it, but it should be a fun receiver to play with.)
