Horizontal Loop for DX

November 16th, 2017

The goal was to get an 80 meter loop in the air, and take advantage of theoretical low angle radiation when operating on higher frequencies. I was only able to get about 200′ of wire in a rectangular shape, at a height of 30′. I made a short section of open wire to feed the loop, and it connects to a 4 to 1 balun at the tuner in the shack. I did not calculate anything, and hoped that since it is a short run that the characteristic impedance of the feedline was negligible.

I have had my share of looses when experimenting, and I am calling this a winner. It performs great on 40 and up. In many cases it out performs my resonant 20 meter dipole (inverted V at 45′). I got lucky and have a decent match on 17m, 15m, 12m, and 6m, bypassing the tuner with SWR<1.5. I do not use 6 meter often, but find it interesting how this loop is matching.

The next step is to see how well 500′ of wire in a loop will perform. Ideally I will get a better install for the longer run. The 200′ loop is something me and a friend put up quickly on a Saturday night, and it has done much better than expected. I may not have enough room for 500′, but the goal is to get more wire in the air.
