Hello,

I was curious. If a matching network was designed to make the SWR at a
band of frequency less than 1.4 to 1, then what would happen if I
inserted a power sensor on the line with a rated SWR of 1.05 to 1 at
this frequency band?

Would that make my overall system SWR 1.4 + .05 = 1.45 to 1?


No, SWR does not do a simple addition. If it is a power sensor that uses a
short piece of transmission line then you have to know the frequency , the
length in wavelengths, the inpedance of the line, and then do some
calculations. It could be slightly beter or worse than it was to start
with. Probably not enough to show on a simple swr meter.
