Why not try a double layered loop? Feed with a 4:1 balun about 1/4 of the way from the corner on the 40 ft side, make a spiral, and send the other side back to the balun. Separate the two layers by about 10 feet, get it at least 15 feet off the ground at the bottom, and it should work. In that small of a garden, you're going to have to compromise.. might as well get as much wire in the air as you can. -SSB I don't think double layering will have much change, except for where it's resonant. It should still act pretty much the same as a single turn loop of that size. Myself, I think he would be best off going with a very high performance short vertical. A loop is gonna be a skywarmer, and a lukewarm one at best. I would layer the garden with almost solid metal, preferably copper wires, or whatever, and run the best, tallest, lowest loss vertical he could get away with. I'd top load it if at all possible. That will greatly improve the current distribution. With a good vertical, he would at least have a chance of having a decent signal. For long haul, nothing else he could install would touch it. I like the inv L idea, but I assume he can't do that for some reason. M3 wrote: Hi, Any designs for a small antenna to work on 160M? My garden is approx 40ft x 17ft. If you line that garden with a lot of radials under the ground, you could have acceptable losses for what you have to work with. Most loss is directly at the base of the vertical. Plant a lot of radials lining the garden, and you will do ok. MK |
