1. [Antennaware] quad (score: 1): Author: john.w1fv@telocity.com (John Kaufmann); Date: Sun, 5 Jan 2003 10:56:29 -0500; Here are the results of a couple of quad models in free space: 2 element quad with reflector: gain = 7.29 dBi, F/B = 20 dB 2 element quad with director: gain = 6.22 dBi, F/B = 4 dB The gain and F/B c; /archives//html/Antennaware/2003-01/msg00006.html (6,988 bytes)
2. [Antennaware] Re: NVIS -- modeling, mininec vs nec-2 disparity (score: 1): Author: john.w1fv@telocity.com (John Kaufmann); Date: Fri, 7 Jun 2002 09:51:40 -0400; I would not trust the MiniNEC ground model with horizontal wires close to ground. "Close" means under a height of .2 wavelengths. The Sommerfeld-Norton ground model is reported to be reliable, howeve; /archives//html/Antennaware/2002-06/msg00010.html (8,742 bytes)

4. [antennaware] antenna analyzers (score: 1): Author: john.w1fv@telocity.com (John Kaufmann); Date: Sat, 2 Feb 2002 13:14:44 -0500; I've used the MFJ and the AEA. The MFJ has the advantage of being very easy to use, with a simple user interface. It is also much less expensive than the AEA. However, it has one major drawback (like; /archives//html/Antennaware/2002-02/msg00004.html (8,578 bytes)
5. [antennaware] vertical modelling (score: 1): Author: john.w1fv@telocity.com (John Kaufmann); Date: Mon, 18 Jun 2001 07:51:01 -0400; It sounds as if you are using MININEC to model your antenna. If this is the case, you will not get accurate results for the "elevated" radials. NEC-2 is more accurate for low elevated radials, althou; /archives//html/Antennaware/2001-06/msg00002.html (9,172 bytes)
