Adding an ideal reactance of -155 ohms


Bit is not a fixed reactance, it is a transmission line element, and

you
should model it as that, even if lossless.

If you specified it in wavelengths, wouldn't that have a constant
reactance.

The real stub is a fixed physical length, and its reactance changes with
frequency.

Good morning (here) Mr. Duffy

It was in meters...

Please, remember the proposition to validate or refute. Once validated
(if it is), then we could think about details

You know, I was not trying to find out if it is the best matching
method but whether it is a viable method. For example: In precedent
post I said I was using a "coarsely" reactance for a basic hypothesis
test because my dictionary suggest that word, perhaps I should have
written: rudely? approximately?

SRI, this is not my natural language and I may not adequately
explained my goal...
