R is not zero. It can be several ohms. And lots of amps can flow.


OK Reg, but in this ideal rf environment we Amateurs live in R is zero.

Just to add a 1/2-wave shorted stub also makes a mess of the tuning of the
remainder of the antenna system at all other frequencies. It must be
designed "in".

That should be fairly obvious to the most casual observer. :-).
In the receive applications that I have used a 1/2 wave shorted stub as a
notch filter, I can assure you I did not have lots of Amps flowing.
