I used the rest of my 500 feet roll of 14g stranded

and made the biggest loop I could build. It goes from the far corners of
the back yard to the left front corner of the house to a support on the
right side of the house, a kind of truncated rectangle I guess, 15 feet
or so above my desert oasis. I terminated it with an MFJ-913 4:1 BalUn.
The antenna works great for SWL (can't steer it unfortunately for ham
radio) and MWDX. It is very quiet noise from the neighbors. It also
fades less. I can get every powerhouse in the West (except POS KFI) at
night, perfectly. No dimmers buzzing. No plasma TVs. No RV Battery
chargers.
I don't know how long it is, but I really lucked out. It resonates at
3599 KHz, and is below 4:1 everywhere. There is another resonance at
around 15 MHz.
So it appears to be an 80 meter full wave horizontal loop. It involved
the roof, so I had to go slow. It took about 2 hours to erect.
