Very cool! I have almost the exact same thing setup at my qth as my permanent antenna. Its about 140 feet of wire in a horizontal triangle up about 20ft over my house. At the feed point I'm using an ldg 4:1 unun fed with 50 ohm coax but no choke on mine. I have about 75ft of coax back to the radio and don't seem to get rf back in the shack. It resonates on 40m, 20m, 15m, 10m, and 6m. Looks like it could easily do the WARC bands with a tuner. Loops are quickly becoming my favorite kind of antenna. You get more harmonics, slight gain over a dipole, and good noise rejection. I made a 20m loop for my pota ops, in conjunction with a 12m spiderbeam. I find it is 3-4 s units quiter than my end fed half wave which everyone is fawning over these days. I was wondering if it were possible to put 40m of wire on that mast and so its great to see an example. 73s
