1. [TowerTalk] Hairpin (score: 1): Author: w8ji.tom@MCIONE.com (Tom Rauch); Date: Sun, 05 Jul 1998 18:35:33 +0000; There were some good responses to this question, but I'd like to add one more thing. This also applies to ANY antenna. If the feedline is more than a few degrees electrical length between the antenna; /archives//html/Towertalk/1998-07/msg00183.html (8,365 bytes)

If the transmission line is one-half (electrical) wavelength or a multiple, then the load's (antenna's) impedance is duplicated a; /archives//html/Towertalk/1998-07/msg00184.html (10,086 bytes)
3. [TowerTalk] Hairpin (score: 1): Author: k4sb@mindspring.com (K4SB); Date: Mon, 06 Jul 1998 02:08:35 -0700; Hi Tom and all Maxwell-Reflections Quote Page 2-7 1. The SWR in a feed line cannot be changed, adjusted, or controlled in any practical manner by varying the line length. 2. If SWR readings change si; /archives//html/Towertalk/1998-07/msg00196.html (10,085 bytes)
4. [TowerTalk] Hairpin (score: 1): Author: tao@skypoint.com (Tod Olson); Date: Sun, 5 Jul 1998 23:23:18 -0600; I read and then re-read the two messages. I suppose the easiest thing is to simply say you are both right. The quotes from Walter's book are OK, but what Tom has said is OK too. I think you guys are; /archives//html/Towertalk/1998-07/msg00200.html (7,222 bytes)

Cebik); Date: Mon, 6 Jul 1998 07:01:44 -0400 (EDT); Tod, The out of phase condition arises because the citations from Walt Maxwell refer to SWR. Tom's note refers to the impedance to be measured. The SWR (ignoring line losses) does not change. But, e; /archives//html/Towertalk/1998-07/msg00203.html (10,160 bytes)

I took the boom down from storage and it appears the beta match was a mod. On the TOP side of the boom was the original self tapping screw hole, whi; /archives//html/Towertalk/2004-09/msg00700.html (7,820 bytes)

The 'loop' is 25.5 inches either side of the boom attachment point, thus is 51 inches overall. The shape is almost a continuous curve from driven element attachment point to boom; /archives//html/Towertalk/2004-09/msg00715.html (9,243 bytes)
