But I still shy away from matching impedances with a "choke".
I would match impedances with a balun or RF transformer.
Jerry Sevick, W2FMI, says a *balun IS a choke* plus
a transmission line. He wrote in "Building and Using
Baluns and Ununs":

The lumped element equivalent of the transmission line itself is a
repetitive pattern of inductors and capacitors. If all inductors are
chokes, then the transmission line itself is composed of chokes.
