1. Topband: Ground conductivity discussions (score: 1): Author: Dennis Ashworth <dennis@ashworth.org>; Date: Sat, 3 Dec 2022 08:54:11 -0800; Very interesting and timely discussions on radials and ground conductivity. Im currently rebuilding an 80M broadside array (with shortened, top loaded elements) in SW Utah that Ive modeled at 12 ohms; /archives//html/Topband/2022-12/msg00006.html (8,725 bytes)
2. Re: Topband: Ground conductivity discussions (score: 1): Author: Grant Saviers <grants2@pacbell.net>; Date: Sun, 4 Dec 2022 09:19:27 -0800; Sounds like a great project. Isn't the reality that conductors (radials) in or near lossy mediums (earth, even salt water) have loss? And that the near field extends beyond the 1/4wl of the radials?; /archives//html/Topband/2022-12/msg00009.html (10,604 bytes)

My 160m antenna is a bit longer than 1/4wl - trimmed in length so that the resistivity component of Z was 50 ohms. It's got Xl of course, so I use a; /archives//html/Topband/2022-12/msg00010.html (12,432 bytes)
