Horizontal Loop for DX

November 16th, 2017 by Joe Stokes Leave a reply »

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.
