So, what's in your back yard (or on your roof, or in your attic....)? Steve Mine defines "homemade", but worked out well for me: I found a spool of 14 gauge stranded with insulation that precisely matches the color of the ceilings in our home. Using white electrical staples, I mounted it at the wall-to ceiling point, and ran it straight through the family room, down a long hallway, and into my shack, across the ceiling there, and terminating about 3' above my receiver, where I joined it to coax and the coax to an antenna connector for input. It is 55' long, and mounted 7.5 feet above grade. I used this alone for about a month, and was very pleased with the results. In an effort to "notch it up a bit" (don't all antenna experimenters?) I ran an additional 55' of the wire around the ceiling/wall juncture of my shack. It goes around exactly 1 and 1/4 times, (also 7.5 feet up) and again drops to 3' above the receiver, where it joins the coax at the same point as the original wire. I now had a 110' longwire antenna, center-tapped. I read here a few months back where a poster remarked that doubling a 50' random wire to 100' would increase signal strength by only 3dB. That's basically what I found, too. There is a slight edge to signal strength since I went to 110', but only slight. The 55' alone gave me good results. Receiver is an Icom R-75, by the way. I like the relative "invisibility" of teh way I did it. 110' of antenna, and no one even notices it unless it's pointed out to them. Even my wife didn't notice it for more than 6 weeks after I installed it, and had no problem with it when she did notice it ("Gee,you can barely see it.") Comments/suggestions welcome - I'm always trying to learn more. Tony |
