As I said, the reflection coefficient at '+' can be calculated accurately using just the characteristic impedances, as shown by Born and Wolf. Why is this so hard for you to understand? What is the rho of the following? source---50 ohm feedline---+---150 ohm feedline---load150 "Just the characteristic impedances" are given. You say you can "calculate rho accurately" from just that. So prove your statement. (load150 means the load is not equal to 150 ohms) If you say rho = (150-50)/(150+50) then you are mistaken. If Born and Wolf say rho = (150-50)/(150+50) then Born and Wolf are mistaken. rho = Vref/Vfwd and, contrary to what you say, there is *NOT* enough information given to calculate rho. -- 73, Cecil, W5DXP |
