2. Re: [TowerTalk] weird coax (score: 1): Author: George Dubovsky <n4ua.va@gmail.com>; Date: Sat, 10 Dec 2011 10:46:29 -0500; Dunno, Dave, but I ran into something that sounds like that, about 30 years ago. The center conductor was something with measurably higher resistance than copper. I was told it was for making delay l; /archives//html/Towertalk/2011-12/msg00267.html (8,525 bytes)

Re: [TowerTalk] weird coax (score: 1): Author: Jim Lux <jimlux@earthlink.net>; Date: Sat, 10 Dec 2011 07:58:21 -0800; The delay line stuff actually has a spiraled inner conductor (to increase the series L (so that sqrt(L*C) is big), so a foot of coax has a lot more than a foot of (very small diameter) copper wire in; /archives//html/Towertalk/2011-12/msg00268.html (8,470 bytes)

Re: [TowerTalk] weird coax (score: 1): Author: "K1TTT" <K1TTT@ARRL.NET>; Date: Sat, 10 Dec 2011 21:44:44 +0000; the construction is similar, but this is thicker than rg-62 and the center conductor is not 22ga copper or copper/steel like rg-62. This stuff is definitely intentionally lossy, the center conductor; /archives//html/Towertalk/2011-12/msg00273.html (7,898 bytes)

Re: [TowerTalk] weird coax (score: 1): Author: "Rick Mainhart" <mainhart@triad.rr.com>; Date: Sat, 10 Dec 2011 15:31:59 -0500; That sounds like RG-62, a 93 ohm coax that was used a long time ago for one of the LAN standards of the time. Center conductor is lying inside a poly tube? This coax was also used in automobile AM ra; /archives//html/Towertalk/2011-12/msg00280.html (7,253 bytes)
6. Re: [TowerTalk] weird coax (score: 1): Author: Andy <ai.egrps@gmail.com>; Date: Sun, 11 Dec 2011 23:28:18 -0500; I am trying to understand why lossy wire would be wanted. One use for coax delay lines, was oscilloscopes, so you could see the part of the waveform it was triggering on. Lossy line would result in; /archives//html/Towertalk/2011-12/msg00290.html (7,938 bytes)

Re: [TowerTalk] weird coax (score: 1): Author: David Robbins <k1ttt@verizon.net>; Date: Mon, 12 Dec 2011 06:29:59 -0600 (CST); I don't know if i can trust my meters with such a high loss, but i think it is around 150 ohm... but i'm sure that none of the methods i used take into account the high loss. for instance, the minivn; /archives//html/Towertalk/2011-12/msg00292.html (9,415 bytes)
