1. [Antennaware] Vertical Dipoles (score: 1): Author: David Gould <dave@g3ueg.co.uk>; Date: Tue, 29 Dec 2009 17:38:38 +0000; This may be slightly off-topic but hopefully not too much!! I would like to build a vertical dipole for 20m with the bottom about 1m off the ground, to compliment a beam, to give me a quick omni-dire; /archives//html/Antennaware/2009-12/msg00006.html (7,522 bytes)

Re: [Antennaware] Vertical Dipoles (score: 1): Author: "K9AY" <k9ay@k9ay.com>; Date: Tue, 29 Dec 2009 14:00:25 -0600; Dave, One of my past projects was a no-radial multi-band vertical with a feed similar to what you propose. I found two alternatives for isolating the feedline. The first was a 1.77:1 transmission lin; /archives//html/Antennaware/2009-12/msg00007.html (8,949 bytes)

Re: [Antennaware] Vertical Dipoles (score: 1): Author: Joe Reisert <Joe@Reisert.org>; Date: Tue, 29 Dec 2009 16:06:48 -0500; David, I made quite a few vertical 1/2 wavelength dipoles from 30 MHz up but the same principles should work at lower bands albeit much larger! What I did was to run the coax down inside the lower 1/; /archives//html/Antennaware/2009-12/msg00008.html (9,489 bytes)
4. [Antennaware] Vertical Dipoles (score: 1): Author: Norman Alexander <npalex@bellsouth.net>; Date: Tue, 29 Dec 2009 14:53:51 -0800 (PST); The type of antenna you described is often referred to as a coaxial center fed dipole. The problem you have to solve is removing the interaction of the coax exiting the end of the array, RF decouplin; /archives//html/Antennaware/2009-12/msg00009.html (8,272 bytes)
5. Re: [Antennaware] Vertical Dipoles (score: 1): Author: Ross Primrose <n4rp@aiko.com>; Date: Tue, 29 Dec 2009 19:19:04 -0500; You might also look at a 20m vertical end-fed Zepp, if you make the matching section out of coax, iy could be on the ground, and essentially part of the feedline... 73, Ross N4RP -- FCC Section 97.31; /archives//html/Antennaware/2009-12/msg00010.html (8,633 bytes)
6. Re: [Antennaware] Vertical Dipoles (score: 1): Author: "K9AY" <k9ay@k9ay.com>; Date: Wed, 30 Dec 2009 10:50:45 -0600; One more option is a ground plane, with two, three or four sloping radials. With this configuration, you can achieve a low-VSWR match by adjusting the angle of the radials, and coupling/common-mode o; /archives//html/Antennaware/2009-12/msg00011.html (7,549 bytes)
7. Re: [Antennaware] Vertical Dipoles (score: 1): Author: David Gould <dave@g3ueg.co.uk>; Date: Thu, 31 Dec 2009 12:12:51 +0000; First, thanks to all who have responded both on and off the reflector, with some very useful information. I would just like to add my reasoning for asking the original question. As well as the RF per; /archives//html/Antennaware/2009-12/msg00012.html (8,164 bytes)
