1. [TowerTalk] HF Ground Parameters (score: 1): Author: Brian Beezley <k6sti@att.net>; Date: Thu, 28 Mar 2024 13:10:59 -0700; Ground permittivity and conductivity are needed to model an antenna over ground. Accurate values are particularly important for vertical antennas and for horizontal antennas with low conductors. You; /archives//html/Towertalk/2024-03/msg00111.html (8,575 bytes)
