1. Topband: Radial system gain (score: 1): Author: "Tom Rauch" <w8ji@contesting.com>; Date: Fri, 29 Sep 2006 15:35:41 -0400; Anyone wanting to see actual measurements of radial systems needn't look very far. You can download Brown, Lewis, and Epstein's data from k6MHE's site: http://k6mhe.com/BLE.html If you go to page 12; /archives//html/Topband/2006-09/msg00154.html (8,903 bytes)
2. Topband: Radial system gain (score: 1): Author: Bill Tippett <btippett@alum.mit.edu>; Date: Fri, 29 Sep 2006 16:32:05 -0400; W8JI: especially while Omni. There just isn't any magic. Simple "magic" for Omnidirectional gain: 10 log (X / 1.5kW) = +10 dB. Solve for X.

3. Re: Topband: Radial system gain (score: 1): Author: "Tom Rauch" <w8ji@contesting.com>; Date: Fri, 29 Sep 2006 19:11:58 -0400; Correction: That's wrong. I said .4dB and it is 20 log 192/196 or 0.2dB and that makes this wrong We would gain a whopping 0.2 dB going from 60 radials to 113 radials when the radials are 1/2 wave lo; /archives//html/Topband/2006-09/msg00157.html (8,000 bytes)

That's quite useful for broadcasters, as that's where the consumer radios are, but do we know by measurement of some kind what the results would be at even 5 deg; /archives//html/Topband/2006-10/msg00001.html (8,975 bytes)
6. Re: Topband: Radial system gain (score: 1): Author: "Tom Rauch" <w8ji@contesting.com>; Date: Sat, 30 Sep 2006 15:20:53 -0400; Yuri brought up the point that the large ground system aided low wave angles, giving four square gain from an omni antenna. The fact is there just isn't that much power being wasted close to the ant; /archives//html/Topband/2006-10/msg00002.html (10,427 bytes)
