1. [TowerTalk] 80 meter dipole (score: 1): Author: Tom Osborne <w7why@frontier.com>; Date: Sun, 20 Jul 2014 17:36:21 -0700; I recently put up a dipole for 80 and used some RG-6 CATV coax to feed it. Good news is that I cut it for 3550 and the SWR is about 1.3:1 there. Bad news is that it stays pretty much the same all the; /archives//html/Towertalk/2014-07/msg00145.html (7,112 bytes)
2. Re: [TowerTalk] 80 meter dipole (score: 1): Author: Dan Hearn <n5ardxcc@gmail.com>; Date: Sun, 20 Jul 2014 19:12:51 -0700; Tom: How high is your dipole? Unless it is well over 1/2 wavelength, the feed point impedance is probably around 25 ohms. You are feeding it with 75 ohm coax, a bad mismatch. Do you have a line choke; /archives//html/Towertalk/2014-07/msg00147.html (8,273 bytes)
3. Re: [TowerTalk] 80 meter dipole (score: 1): Author: David Gilbert <xdavid@cis-broadband.com>; Date: Sun, 20 Jul 2014 20:25:18 -0700; You didn't say how long the coax is. It makes a difference. Dave AB7E Is the wide bandwildth because the coax is so lossy? It is the double shielded stuff with 2-layers of foil and 1-layer of braid.; /archives//html/Towertalk/2014-07/msg00151.html (8,091 bytes)
4. Re: [TowerTalk] 80 meter dipole (score: 1): Author: "Wes Attaway $N5WA$" <wesattaway@bellsouth.net>; Date: Sun, 20 Jul 2014 23:02:49 -0500; It looks like you have a lot of loss somewhere in the system, unless you have a really long coax run. If the run is only 100' or 150' then I don't think you would see such a flat SWR curve unless eit; /archives//html/Towertalk/2014-07/msg00155.html (8,879 bytes)
5. Re: [TowerTalk] 80 meter dipole (score: 1): Author: Tom Osborne <w7why@frontier.com>; Date: Sun, 20 Jul 2014 21:45:07 -0700; The coax run is about 90 feet or so - maybe 100. One other thing - the wire I am using is some CAT 5 cable and it has 6 wires in it. I just stripped and wrapped the wires on the end where I hooked th; /archives//html/Towertalk/2014-07/msg00156.html (8,114 bytes)
6. Re: [TowerTalk] 80 meter dipole (score: 1): Author: David Robbins <k1ttt@verizon.net>; Date: Mon, 21 Jul 2014 06:27:42 -0500 (CDT); it could be lossy coax, or the dipole could be too close to the ground or some other object that is tuned near the 80m band by accident and is absorbing lots of the power. for instance maybe a rain g; /archives//html/Towertalk/2014-07/msg00159.html (8,669 bytes)

Re: [TowerTalk] 80 meter dipole (score: 1): Author: Al Kozakiewicz <akozak@hourglass.com>; Date: Wed, 23 Jul 2014 13:37:14 +0000; FWIW, I have an 80m dipole in an inverted Vee configuration with the apex at the top of the gable end of a one story section of my house, perhaps 18 feet, and the ends about 4 - 6 feet off the ground; /archives//html/Towertalk/2014-07/msg00195.html (9,369 bytes)
