I have what I think is a maco v 58 or something like it. I have set it up just as the manual says. It seems to have a direct short? But I guess this is how it is designed? I thought I was pretty good at setting up antennas, guess this one has me stumped! When you plug in the coax all white noise goes away and swr is maxed out I changed th es0-239 and the feed wire to the loop and just kenw I had I wooped....same results, did iI forget an insulator or am I just not understanding the consept of this loop gamma match?
