1. [TowerTalk] accuracy of antenna analyzers (score: 1): Author: "Jim Lux" <jimlux@earthlink.net>; Date: Thu, 9 Dec 2004 20:40:25 -0800; Does anyone know of any description or analysis of the accuracy of the various antenna analyzers. The MFJ analyzers use 3 A/Ds to measure detected voltages to 8 bits, and then they compute R and X fr; /archives//html/Towertalk/2004-12/msg00233.html (7,849 bytes)

Re: [TowerTalk] accuracy of antenna analyzers (score: 1): Author: "Jim Brown" <jim@audiosystemsgroup.com>; Date: Fri, 10 Dec 2004 08:11:14 -0600; I have spent a fair number of hours with a CIA-HF, borrowed from another ham, and own an MFJ-259B that I've calibrated per Tom Rauch's applications note. Tom says that the concepts of the two analyze; /archives//html/Towertalk/2004-12/msg00235.html (8,871 bytes)

Re: [TowerTalk] accuracy of antenna analyzers (score: 1): Author: "Michael Tope" <W4EF@dellroy.com>; Date: Fri, 10 Dec 2004 09:44:36 -0800; FWIW, the MFJ-269 uses 12bit A/D's and displays impedance up to 1500 ohms. I haven't sat down a real careful comparison (e.g. calculating percentage error), but the MFJ-269 seems to produce readings; /archives//html/Towertalk/2004-12/msg00238.html (10,383 bytes)
