Linear decoupling traps

Theory says that whatever condition exists at far end of 1/4 wave
stub will appear at fed end.

That's true for an ideal 1/2WL stub but for an
ideal 1/4WL stub, an open at the far end will
appear as a short at the feed end and a short
at the far end will appear as an open at the
feed end.
