1. [VHFcontesting] Loop Yagi theory (score: 1): Author: Mark Spencer <mark@alignedsolutions.com>; Date: Mon, 3 Oct 2016 10:38:29 -0700; Hi does anyone know of a web site that explains why loop yagis are horizontally or vertically linearly polarized ? I recently gave a presentation to a local club on VHF and up weak signal operating a; /archives//html/VHFcontesting/2016-10/msg00001.html (7,500 bytes)
2. Re: [VHFcontesting] Loop Yagi theory (score: 1): Author: Zack Widup <w9sz.zack@gmail.com>; Date: Mon, 3 Oct 2016 13:12:39 -0500; It's basically the same idea as with a quad antenna. A loop (either circular or square) fed at the bottom or top has current peaks at the feedpoint and opposite side of the quad or loop, and voltage; /archives//html/VHFcontesting/2016-10/msg00002.html (8,771 bytes)
3. Re: [VHFcontesting] Loop Yagi theory (score: 1): Author: Bill Olson <callbill@hotmail.com>; Date: Mon, 3 Oct 2016 19:24:43 +0000; yeah, like a "cubical quad", which is a full wave loop element .. what makes it different from the HF quad you normally think of is that all the low impedance points are all tied together to ground (; /archives//html/VHFcontesting/2016-10/msg00003.html (11,170 bytes)
4. Re: [VHFcontesting] Loop Yagi theory (score: 1): Author: Mark Spencer <mark@alignedsolutions.com>; Date: Mon, 3 Oct 2016 13:10:00 -0700; Thanks all for the on and off list responses. The reminder re the current and voltage min and max points in the circular elements was helpful. 73 Mark S VE7AFZ Sent from my iPhone ___________________; /archives//html/VHFcontesting/2016-10/msg00004.html (15,772 bytes)
5. Re: [VHFcontesting] Loop Yagi theory (score: 1): Author: jon jones <n0jk@hotmail.com>; Date: Mon, 3 Oct 2016 20:51:14 +0000; Zack and Bill's explanations were good regarding Mark's question. The polarization of an antenna depends on the orientation of the electric field. Recall electromagnetic radiation (radio waves) consi; /archives//html/VHFcontesting/2016-10/msg00005.html (8,468 bytes)

Re: [VHFcontesting] Loop Yagi theory (score: 1): Author: "Mike (KA5CVH) Urich" <mike@ka5cvh.com>; Date: Wed, 5 Oct 2016 16:26:44 -0500; I don't know of any web-sites but I would merely explain that especially at those frequencies the shape of the loop, no matter how many sides or a complete circle is irrelevant as long as the LENGTH; /archives//html/VHFcontesting/2016-10/msg00011.html (8,465 bytes)
