Topband: EZNEC Ground Errors (score: 1): Author: "Roger Kennedy" <roger@wessexproductions.co.uk>; Date: Fri, 11 Dec 2020 08:59:15 -0500; Guy I have ALWAYS thought that the various Computer-based modelling of Ground and its effect on Antennas is WAY off . . . And surely the errors are MOST significant on 160m, not just because Antennas; /archives//html/Topband/2020-12/msg00122.html (8,140 bytes)

Re: Topband: EZNEC Ground Errors (score: 1): Author: Artek Manuals <Manuals@ArtekManuals.com>; Date: Fri, 11 Dec 2020 09:38:39 -0500; OR The propagation mode on 160 is not what we have popularly come to "Accept". There is a growing body of evidence that particularly at gray line that signals often arrive at a higher angles. This is; /archives//html/Topband/2020-12/msg00123.html (9,489 bytes)

To me, it's a kind of "Urban Myth" that 160m DX is all Low Angle propagation. Sure, on 80m it nearly ALWAYS is . . . You MUST have a Vertical to work DX well on; /archives//html/Topband/2020-12/msg00125.html (7,980 bytes)

Re: Topband: EZNEC Ground Errors (score: 1): Author: John Kaufmann via Topband <topband@contesting.com>; Date: Fri, 11 Dec 2020 10:06:41 -0500; I have two receiving antennas on 160: an 8-circle vertical array and a low dipole up 10 feet. I have been noticing that in the first part of the evening, the dipole often hears Europe as well as, or; /archives//html/Topband/2020-12/msg00126.html (11,396 bytes)

A couple of years ago I built a 160m Receiving Loop, which is Vertically polarised. It behaves very differently to my Dipole, I can see huge differe; /archives//html/Topband/2020-12/msg00129.html (8,528 bytes)
