Reflection Coefficient Challenge Solved
Richard Clark wrote:
"The point of the challenge was to illuminate the invalidity of claims that the usual Ham transmitter does NOT exhibit 50 Ohms and that any power returning to it from a mismatched load is reflected fully back toward the load." The impedance a transmitter presents to a reflection is seldom advertised as far as I know. I think it could be measured. If a matchbox exists between the transmitter and the line, it may be adjusted to get the most out of the transmitter. If so, this match should prevent a reflection from reaching the transmitter. If the reflection doesn`t reach the transmitter, there is no place else for the reflection to go other than for another go at the load, given low losses in the matching and feeding systems.
