Your mistake is that you assume the output of the tx is 50 ohms,

Hi Jimmie,

At the risk of yet another, non-quantitative reply I will repeat:
a question that has NEVER been answered by those who know what the
transmitter output Z ISN'T:
"What Z is it?"

in the case
you stated the transmitter must be matched to the impedance it sees looking
into the transmission line.

THAT is true, and it brings us to the point of all this energy
sloshing around until the antenna finally dissipates it out into the
Æther. It is the reflection off the mismatch of the tuner (the
mismatch seen by the antenna as source to the line going back) that
prevents energy from presenting any destructive results to the source
- the whole point of using a tuner in the first place.
