Ok, since you are discussing impedance matching, what was the effect on
VSWR bandwidth.

It seems to me that as you go lower in frequency, the inductive reactance
at the feedpoint becomes less and the series stub reactance becomes
greater, so one aggravates the other.

The question is whether the outcome is narrower than desired or available
with other matches.

Because Mosely's explanation contains so much BS, I have no faith in
anything they have said.



Aside from marketing BS..

Owen raises a good point. You bring the feedpoint Z from 31.8+j2 to
51+j150. Resonating the j150 with a -j150 is fine, but now,you've
effectively got a resonant circuit with moderately high Q, or, at the
very least, more circulating power between matching network and antenna.
