Re: [TowerTalk] Insulated wire, theory (score: 1): Author: "Lux, Jim" <jim@luxfamily.com>; Date: Wed, 21 Sep 2022 07:17:25 -0700; I suspect that EZNEC does it by a similar approach - changing the length of the wire to a slightly shorter length to accommodate the slower propagation in the insulated wire. That may have been done; /archives//html/Towertalk/2022-09/msg00101.html (7,454 bytes)
