What does your software report for a software 40 Ohm line feeding a software 50 Ohm load? That is, when all data points (that is each increment of 1 foot) exhibits 0 Watts returned for 5W applied? My software takes a list of reflected powers, assumes the forward power is five watts, calculates the 50 ohm SWR for each point, and plots them every 0.03WL on a Smith Chart. It was written to accept your data points. If the reflected power above was always zero watts, all those points would be the same point, i.e. a circle of zero radius at the center of the Smith Chart. Take time to plot those 50 ohm SWR points on a Smith Chart with the 0.45 watts reflected point assumed to be the lowest purely resistive point. A picture is worth a thousand words. I have seen that picture before. It was when I designed my SWR meter for a Z0 of 450 ohms and my window-line turned out to have a Z0 of 388 ohms. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
