1. Topband: Tuning 160M Dipole (score: 1): Author: paul ecker <eckerpw@yahoo.com>; Date: Tue, 30 Oct 2012 16:29:40 -0700 (PDT); I put up a 160m dipole but now need to tune it. SWR at low end of band is abt 3 and at top end abt 5. From what I have read this means I need to shorten it. My question is how much should I take off?; /archives//html/Topband/2012-10/msg00375.html (7,206 bytes)

Re: Topband: Tuning 160M Dipole (score: 1): Author: Bob K6UJ <k6uj@pacbell.net>; Date: Tue, 30 Oct 2012 16:56:25 -0700; Paul, Here is a handy on line calculator to help you determine the approx wire length. You can play with putting in different freqs and see how much the wire length changes. I believe with frequency; /archives//html/Topband/2012-10/msg00376.html (7,826 bytes)

Re: Topband: Tuning 160M Dipole (score: 1): Author: "Ulrich Weiss" <dj2ya@t-online.de>; Date: Wed, 31 Oct 2012 10:04:43 +0100; hello Paul, I quite agree with Peter's (DJ7WW) advice, but instead of shortening the ends I would first fold them (tightly) back and check the result... "overshooting" can easily be corrected before; /archives//html/Topband/2012-10/msg00380.html (8,090 bytes)

Re: Topband: Tuning 160M Dipole (score: 1): Author: "Rick Karlquist" <richard@karlquist.com>; Date: Wed, 31 Oct 2012 15:04:54 -0700; It works a lot better to find the frequency of minimum SWR and then it is a simple matter to calculate how much to prune. For example, if the frequency is 10% too low, say 1647 kHz, then remove 10%; /archives//html/Topband/2012-10/msg00401.html (7,771 bytes)
