Hi Tony, There is no such thing as a Low Noise antenna (loop or otherwise). Given that what you build is deaf, that should be a reality check of this presumed quality of the antenna. Well, actually, you built it wrong. However, building it right stands only a partial chance of lowering noise, and not because the antenna has some remarkable quality that is not otherwise found in the plug ordinary dipole. In that sense, the reduction of noise would only follow turning the dipole (or loop, same thing) until the source of that noise fell into a null. This is the conventional method of employing a "Low Noise" antenna. Let me guess. It is a shielded loop. You forgot to leave a gap in the shield. 73's Richard Clark, KB7QHC it is a shielded loop and no the gap is there, thats why I am wondering why its not doing what I thought it would do. |
