antenna coupling via proximity ?
by Neil VillacortaBuer 03 Feb '10

03 Feb '10

Greetings guys-n-gals, I have an over-the-air television antenna question. I have a 4-bay bow-tie UHF antenna that has a beam-width of approx. 45-degrees. About 10-feet in front of it, is a UHF yagi. The antennas are 100-degrees offset from each other (e.g., bow-tie faces North-West, yagi faces East) and I was planning to use a Channel Master Join-Tenna to join the two antennas together onto a single 75-ohm coax. However, I get a BETTER signal level not only the far-away North-West channel (45% vs. 23%) if I don't use the Join-Tenna, leave the yagi in front of the bow-tie, and just connect directly into the bow-tie. I was assuming it was the loss of the Join-Tenna, however, when I had the yagi face NW to the far-away channel, and the bow-tie face East to the local channels, the results were not better on ANY channel. I'm thinking that the Yagi pointed at the strong local channels is coupling the strong local channels in front of the bow-tie antenna, thus giving the bow-tie a 90-degree side-lobe. This WITHOUT the loss from the Join-Tenna is giving me the better signals. Does the make sense ? Comments ? Ideas ? Thanks, :-) neil KE6DCJ

Hi all, Just a note to mention, I can still change my mind, but I think I will check out this hamfest tomorrow that Michael forwarded the info about last Monday. If any SBARC'ers are going I'll see you there, and if not you can ask me about it afterward. I will encourage the vendors there to come to the SBARC Hamfest of course! It will also be an opportunity to try out my pocket-sized Sony "Webbie", or "Snap Camera", I got for Christmas that takes video as well as photos. 73, Dave Hackleman K6VML San Bernardino
