1. [TenTec] OT: SWR & Coax (score: 1): Author: Marinus Loewensteijn <zl2ml@hotmail.com>; Date: Mon, 7 Jul 2008 15:39:13 +0800; When Coax is terminated at the transmitter end and the far end with an impedance that is equal to its defined impedance we will have a SWR of 1:1. Only when the currents on inner conductor and on shi; /archives//html/TenTec/2008-07/msg00103.html (7,530 bytes)

Even when there is a high SWR the current nodes in the two conductors occur the same distance from the (mismatched) load. You can sti; /archives//html/TenTec/2008-07/msg00104.html (8,553 bytes)

I put it up as high as I can. I put RF into it... as much as the transmitter will put out. I enjoy ham radio. Thus, I do not try to underst; /archives//html/TenTec/2008-07/msg00105.html (7,538 bytes)
