1. Topband: Open wire feeder (score: 1): Author: earlham at radiks.net (Iowaguy); Date: Thu Aug 7 22:56:38 2003; Greetings... I've used open wire feeder successfully over the years in some fairly small, limited applications. However, I have a 160 transmit antenna that I'm constructing that will be about 800 cab; /archives//html/Topband/2003-08/msg00031.html (7,630 bytes)
2. Topband: Open wire feeder (score: 1): Author: k4kyv at hotmail.com (Donald Chester); Date: Fri Aug 8 06:57:28 2003; The tuning adjustment at the matching device will be more cricical, since you will be running over a full wavelength of tuned feedline. A given change in frequency will move the current /voltage poi; /archives//html/Topband/2003-08/msg00032.html (7,649 bytes)
3. Topband: Open wire feeder (score: 1): Author: w8ji at contesting.com (Tom Rauch); Date: Fri Aug 8 11:08:06 2003; Don made a very good point. The longer the low-loss feedline (and higher the SWR) the more rapidly peaks and valleys in impedance occur. I had a 1500-foot open wire line of number 8 solid copper spa; /archives//html/Topband/2003-08/msg00033.html (7,935 bytes)
4. Topband: Open wire feeder (score: 1): Author: ve3zi at isys.ca (VE3ZI); Date: Fri Aug 8 11:08:08 2003; Dave I don't think there should be any problems if you are several feet away from the fencing wire, but you do need to be careful to not unbalance the feedline. I base that conclusion on my working (; /archives//html/Topband/2003-08/msg00034.html (7,863 bytes)
5. Topband: Open wire feeder (score: 1): Author: kimba at sprint.ca (Bert Barry); Date: Fri Aug 8 11:08:10 2003; This is true for a feedline badly mismatched at the antenna. I feed a multi-wire rhombic with an 800 foot open wire line (600 ohms) and my SWR is under 1.5 : 1 from over 21 MHz to 3.5 MHz! And the lo; /archives//html/Topband/2003-08/msg00035.html (7,737 bytes)
6. Topband: Open wire feeder (score: 1): Author: richard at karlquist.com (Richard Karlquist); Date: Fri Aug 8 12:01:06 2003; I have 850 feet of open wire line to my 160 vertical. There are numerous photos of it on my web site at http://www.n6rk.com/openwire.html. It is 4 AWG stranded aluminum XHHW wire, spaced 5 inches.

7. Topband: Open wire feeder (score: 1): Author: k4kyv at hotmail.com (Donald Chester); Date: Fri Aug 8 21:39:02 2003; Another approach is to use a multi-wire open wire line, using 4 or more conductors. I have heard of ones using as many as 16 wires configured in a matrix with a variety of patterns in which sets of; /archives//html/Topband/2003-08/msg00040.html (8,468 bytes)
8. Topband: Open wire feeder (score: 1): Author: n0tt1 at juno.com (n0tt1@juno.com); Date: Fri Aug 8 22:31:40 2003; Hi Dave, You're gonna love the low loss of open wire feed!...far less than coax. Are you talking about the line that is about 1" spacing? I would recommend building your own, really...it's easy to do; /archives//html/Topband/2003-08/msg00042.html (10,026 bytes)
9. Topband: Open wire feeder (score: 1): Author: "Gary Smith" <Gary@ka1j.com>; Date: Wed, 04 Feb 2015 14:57:02 -0500; I have 350' of coax going to a remote antenna switch which allows me to select from 5 vertical wires, I just posted about my radial system/plate they are part of. Amazing to me is between these 5 wir; /archives//html/Topband/2015-02/msg00090.html (7,745 bytes)
