Alternate setup using 9:1 UNUN Although not the same as described at KK5JY's site, I get similar results using a different setup with an open-loop: 1) 9:1 UNUN - typically used for non-resonant wires antennas. 2) Use the normal wire attachment at the UNUN to form 3 sides of a square. 3) At the ground terminal of the UnUn, make the 4th side of the square, but don't connect the loop together. Just an inch or two separation. Not critical. 4) Be sure to use a common-mode choke on the feedline. Preferably somewhere close to the loop with a jumper, but the jumper length does not appear to be super-critical - at least on the low bands. You just don't want to fool yourself with a complicated mess of a common-mode random wire, so choke it! Handy for those who want to just get a taste of what's possible with perhaps a 9:1 unun sitting on the shelf, OR for those who simply can't move their log to a new location, and have tried changing corner feeds and there is still that nasty little squeal. Try this option.
