"The most important parameter is not SWR but the reflection coefficient, Gamma." My age is about the same as Reg`s. I have 4 children and 6 grandchildren, and am a veteran of WW-2, but doubt that adds to my credibility. Neither does the beer I had with dinner add authority to what I write. I have a degree in Electrical Engineering, but Americans and probably Brits too view this credential with suspicion. It did open the door to good jobs. Reg expresses disdain for "bibles" such as Terman or Kraus but their writings have endured the test of time and are proved by countless experiments. On page 99 of Terman`s 1955 edition of "Electronic and Radio Engineering" (my textbook was an earlier edition) is found the formula to convert the reflection coefficient into SWR or vice versa. These two parameters are innexorably locked together by formulas (4-22a) and (4-22b). There really is no need to rename the ubiquituos SWR meter as Reg has recommended. This really requires no comment as it isn`t about to happen. Best regards, Richard Harrison, KB5WZI |
