Noise level between two ant types
Cecil Moore wrote: Quads are a lot less noisy than Yagis when the wind is blowing in the Arizona desert. Quads have a DC short across the feedpoint that reduces noise from static buildup. Virtually all Yagi's have dc paths to discharge the elements. The primary reason a quad is quiter is it has no sharp protruding ends that are sticking way out in the air. As a matter of fact if you research the quad, it was initially used to eliminate corona at radio station HCJB. Try this test, wire a small 2.5 MHh RF choke across your antenna and check the before and after noise levels. They will not change. 73 Tom |
