1. Topband: Antenna Comarisons (score: 1): Author: W5UN <w5un@wt.net>; Date: Mon, 11 Oct 2004 11:47:08 +0000; FWIW, on 160 meters I am using a 100' tower with a 4 element 40 meter beam at 100', and a 7 element 6 meter beam at 115'. This towers sits directly behind, and next to my 30'X50' metal building shop,; /archives//html/Topband/2004-10/msg00043.html (8,035 bytes)

It could easily favor one direction 2 dB at the expense of other directions. Maybe you happened to measure it in a direction where it has 2 dB; /archives//html/Topband/2004-10/msg00049.html (9,667 bytes)

Re: Topband: Antenna Comarisons (score: 1): Author: "Tom Rauch" <w8ji@contesting.com>; Date: Mon, 11 Oct 2004 14:09:05 -0400; Anything would only be a guess, because a grounded tower with the coax shield tied to it is a very unpredictable system. Current at the attachment point divides between the ground at the tower base; /archives//html/Topband/2004-10/msg00053.html (7,924 bytes)
4. Topband: Antenna Comarisons (score: 1): Author: dennis o'connor <k8do@mailblocks.com>; Date: Tue, 12 Oct 2004 07:38:38 -0700; W5UN Dave: A shortened vertical on 160 should be down from a taller vertical... Looks like your real world experiment matches theory... Also, any antenna that measures within +- 2dB of a model is doi; /archives//html/Topband/2004-10/msg00057.html (10,334 bytes)
