Don,
You might also consider making it a three sided loop with the apex away from the house to a friendly tree. Several hams are doing it that way and the patterns are not the same as a square loop, but the match and multiband operation is equal, a thought.

Do you have any excess ladder line in the shack? That's about the only thing I can think of. My only rfi has been in amplified speakers on 17m. The feedpoint of my 80 m delta loop is 25' from the shack over the house. The house is not inside the loop but under one corner. 300 ohm line come inside to a manual tuner. The old mfj had a 1:1 balun and the palstar I now use is 4:1 but the 1:1 worked. Their is a gap vertical inside the loop. I used to run 500 w but now run qrp most of the time. Did you have the issue at 100w and is shack on ground or basement level. Also some commented on loops being Nvis antennas and they are on the cut frequency but the elevation take off angle comes down at multiple wavelengths. Their pattern is best compromise at 3 or 4 wavelengths. 73 Mike R Sent from my spy ring ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
