Does anyone have any experience with the Pixel RF PRO-1B magnetic loop receive only antenna? Any comments on its performance compared to a 1/4~ vertical would be most welcome. I'm interested mainly in performance on 160 and 80mtrs. http://www.pixelsatradio.com/product/shortwave-magnetic-loop-antenna/ Dave Harmon K6XYZ[at]sbcglobal[dot]net Sperry, Ok.
