I believe the issue is that RDF is a theoretical calculation comparing the main lobe gain to the overall average gain. The overall average gain essentially results in the assumption that noise is com

I agree. There are times, especially in disturbed condx, when my BOG antennas are "head and shoulders" better than my other antennas.   73 Bruce-K1FZ www.qsl.net/k1fz/bogantennanotes.html       I can

Hi Carl Yes, the concept is assuming equal density noise spread uniform. However there air point everybody wants to hide. Vertical polarized antennas based on phasing elements does change directivity

Hello JC and others, I must take a little issue on being able to measure the vertical arrays. While it may be true that it is hard to measure, you can indeed see the pattern quite well by looking at

Hi Lee, I recently had exactly the same experience with my 160 meter W8JI passive 8-circle array. About six weeks ago intense broadband white noise appeared at my QTH arriving at about 325 degrees az
