1. Topband: Vertical SWR problem (score: 1): Author: <JSimon@GrahamDunn.com>; Date: Fri, 26 Nov 2004 15:45:29 -0800; I've just installed a Titanex V160S vertical (87') with a V160AS (160m only) tuning unit. Yesterday I connected 12 radials (130') each, adjusted the taps on the tuning unit coil with an MFJ SWR analy; /archives//html/Topband/2004-11/msg00233.html (7,154 bytes)

Re: Topband: Vertical SWR problem (score: 1): Author: "George & Marijke Guerin" <gmguerin@voyager.net>; Date: Fri, 26 Nov 2004 23:23:46 -0500; Jim, Move the tap from the vertical toward the hot end of the loading coil further to load the antenna down toward 1825 by putting more inductance in the circuit. For better ground add some more radi; /archives//html/Topband/2004-11/msg00234.html (9,109 bytes)

Re: Topband: Vertical SWR problem (score: 1): Author: Pete Smith <n4zr@contesting.com>; Date: Sat, 27 Nov 2004 07:21:06 -0500; Hi Jim -- I assume you've tried what George suggested, without any luck, but it is the right thing to do given the symptoms. Didn't you say that the tap was already all the way to the antenna end of; /archives//html/Topband/2004-11/msg00236.html (10,751 bytes)

Re: Topband: Vertical SWR problem (score: 1): Author: DVoss@t-online.de (Dieter Voss); Date: Sat, 27 Nov 2004 15:25:13 +0100; Hallo Jim, hello together, the problem with the V160 is, that the resistance over perfect ground is about 11.5 Ohms. The tuning unit uses - as far as I know - only a loading coil. By using this with; /archives//html/Topband/2004-11/msg00237.html (9,186 bytes)

6. RE: Topband: Vertical SWR problem (score: 1): Author: "Garry Shapiro" <garry@ni6t.com>; Date: Sun, 28 Nov 2004 18:19:36 -0800; It's not just BC energy that wacks out the MFJ. At 3B9R five years ago, I could not get the Titanex tuned until I had asked JA3IG, one of our team, to QRX in the middle of his 15m SSB run. He was not; /archives//html/Topband/2004-11/msg00248.html (9,441 bytes)
