That is very similar to what the Maxcom Antenna Matcher
did. It was reviewed (and panned) in November 1984 QST.
As you suspected, almost all the power would go into the
dummy load and very little would be radiated.

Honestly, it's not a very good idea. :-)

Hello, and generally not if maximizing operating efficiency (the portion
of available transmitter power that is being radiated by the antenna) is
of concern. However, placing a low-loss pad between the output of one
device and the input of another can be a simple, inexpensive broadband
matching technique if the power loss in the pad can be tolerated .
