1. [TowerTalk] Improving my dipole (score: 1): Author: "Art Boyars" <art.boyars@verizon.net>; Date: Mon, 27 Jun 2005 21:33:54 -0400; On the CQ-Contest Reflector K7QQ said: "You have to keep in mind that the best antenna doesn't exist. You can only get up what you can and it is never enough." Well that's where I am, but I'd like ad; /archives//html/Towertalk/2005-06/msg00611.html (9,380 bytes)

Re: [TowerTalk] Improving my dipole (score: 1): Author: Jim Lux <jimlux@earthlink.net>; Date: Mon, 27 Jun 2005 21:15:07 -0700; <snip> Doesn't take much weight in the middle to pull it down, even with thousands of pounds of tension. It's that 1/sin(theta) thing. My own experience has been that keeping the ends out of the tree; /archives//html/Towertalk/2005-06/msg00613.html (9,882 bytes)

Length can be increased as necessary by allowing an additional 10 to 15 feet of wire to hang down vertically at each end. 100-ft is not a bad len; /archives//html/Towertalk/2005-06/msg00615.html (10,955 bytes)

Re: [TowerTalk] Improving my dipole (score: 1): Author: Jan Erik Holm <sm2ekm@telia.com>; Date: Tue, 28 Jun 2005 07:26:14 +0200; I would run high Z open wire feeder to it, it will then even work on 75m with very little degraded performance compared to a 1/2wl for 75m, less then a dB. Best is to get a good balanced tuner, somet; /archives//html/Towertalk/2005-06/msg00617.html (10,363 bytes)
5. Re: [TowerTalk] Improving my dipole (score: 1): Author: Jan Erik Holm <sm2ekm@telia.com>; Date: Tue, 28 Jun 2005 13:40:24 +0200; I must correct myself. If you use insulated wire and dont run too high power, that is what I mean below. Guess the best/safest is not to let the wire get in contact with the tree.

Re: [TowerTalk] Improving my dipole (score: 1): Author: "Keith Dutson" <kdutson@sbcglobal.net>; Date: Tue, 28 Jun 2005 10:11:29 -0500; I would hang the dipole with extra wire pointing down instead of in the trees. IOW, move the suspension line on both ends toward the center. There is little current at the ends. Keep the ladder line; /archives//html/Towertalk/2005-06/msg00632.html (11,078 bytes)

Re: [TowerTalk] Improving my dipole (score: 1): Author: "larryjspammenot@teleport.com" <larryj@teleport.com>; Date: Tue, 28 Jun 2005 11:17:56 -0700 (GMT-07:00); One thing that I've never seen mentioned anywhere is a multiple-band dipole fed with ladder line. The reason I'm curious about it is that I used to have an 80-Meter Inverted Vee fed with ladder line,; /archives//html/Towertalk/2005-06/msg00655.html (12,888 bytes)
8. Re: [TowerTalk] Improving my dipole (score: 1): Author: "Keith Dutson" <kdutson@sbcglobal.net>; Date: Tue, 28 Jun 2005 14:07:20 -0500; Yes. Multiple wires from the same feed point do an adequate job on multiple bands.. Be sure to separate the wires about 2 or three inches for best performance. The reason 80 performance is different; /archives//html/Towertalk/2005-06/msg00656.html (14,453 bytes)

Re: [TowerTalk] Improving my dipole (score: 1): Author: "Buck - N4PGW" <n4pgw-list2@towncorp.net>; Date: Tue, 28 Jun 2005 15:18:27 -0400; If you are running several hundred feet, maybe you could save some loss, but if you are running RG-8U on 160 and 80 meters, I think the loss is negligible on 100 feet to a matched antenna.

I have always separated mine 4-8 inches apart. At 8 inches, I can trim one antenna, reverse calculate the formula and trim the rest of the antennas by measurement acc; /archives//html/Towertalk/2005-06/msg00658.html (9,427 bytes)

The reason I'm curious about it is that I used to have an 80-Meter Inverted Vee fed with ladder line, and the performance was great on 80M.
