1. [TowerTalk] Coax Resiliency (score: 1): Author: "Michael Hatzakis, Jr" <mikehatzakis@yahoo.com>; Date: Tue, 16 Sep 2003 17:07:27 -0700 (PDT); Cut off 10 foot sections of LMR-400 Ultraflex after putting up tower. I left them outside for two weeks during which time there was a heavy rain. I want to use the peices to make 3-5 foot patch cords; /archives//html/Towertalk/2003-09/msg00432.html (8,206 bytes)

RE: [TowerTalk] Coax Resiliency (score: 1): Author: "Steven Gehring" <stevekz9g@verizon.net>; Date: Tue, 16 Sep 2003 21:21:29 -0700; Hi Michael, You could cut off a couple of feet from each end and still be ok, I believe. You could also check the cable with a megger, a piece of test equipment that measures feed line insulation res; /archives//html/Towertalk/2003-09/msg00441.html (10,057 bytes)

Re: [TowerTalk] Coax Resiliency (score: 1): Author: "Jim Lux" <jimlux@earthlink.net>; Date: Tue, 16 Sep 2003 21:35:06 -0700; Install a connector on one end, hook up antenna analyzer, measure VSWR/reflection coefficient at frequency of interest... VSWR should be infinite (unless you just happen to have the "wrong" length)..; /archives//html/Towertalk/2003-09/msg00442.html (9,566 bytes)

Re: [TowerTalk] Coax Resiliency (score: 1): Author: "Michael Tope" <W4EF@dellroy.com>; Date: Tue, 16 Sep 2003 22:42:01 -0700; I would peel back a few inches of the jacket to see if the braid is corroding due to water intrusion. If the braid is clean, put some connectors on it and see if it works (it should run cool with a 1; /archives//html/Towertalk/2003-09/msg00444.html (9,923 bytes)
5. Re: [TowerTalk] Coax Resiliency (score: 1): Author: Red <RedHaines@centurytel.net>; Date: Wed, 17 Sep 2003 09:30:27 -0500; The line loss is one of the characteristics that may be degraded by moisture intrusion or other degradation of coax. It is easily measured by measuring impedance of the coax with one end either short; /archives//html/Towertalk/2003-09/msg00451.html (9,547 bytes)

Re: [TowerTalk] Coax Resiliency (score: 1): Author: "Jim Lux" <jimlux@earthlink.net>; Date: Wed, 17 Sep 2003 07:59:19 -0700; I believe the original poster had a bunch of short chunks, and might not have a whole 1/4 wavelength. Same thing works, though.. measure the Z looking into a mismatch, just you have to do more math; /archives//html/Towertalk/2003-09/msg00453.html (9,923 bytes)

RE: [TowerTalk] Coax Resiliency (score: 1): Author: "Steven Gehring" <stevekz9g@verizon.net>; Date: Wed, 17 Sep 2003 14:28:33 -0700; All: If I'm not mistaken, the megger won't generate more than 500 to 1000 volts with VERY little current. If the coax can't handle this basic leakage test, it's trash. If memory serves me right, the; /archives//html/Towertalk/2003-09/msg00460.html (10,682 bytes)
