Where does it go? (mismatched power)

If you are designing a tuner, where would you design it to go?
Hi Geoff,
You would put it closer to the antenna.
If you connect a tuner and it is "tuned", none of the power is reflected
back to the transmitter.
Obviously it has to go somewhere.
From the perspective of the transmission line in between, when it hits
the discontinuity of the tuner, it is reflected back to the antenna.
The antenna drains away some of that power (just as it did in the
original pass). The process repeats (the antenna is still partially
reflective) and is further sustained with new cycles of energy.
There are finer details that shift these dynamics.
