Jim, that is the path of the RF driving power.

##  IMO, it all starts at the cathode and has to end there, its just a loop.
The C2 cap in any  PI tuned input is the return for the
rf cathode current.  Without the tuned input, the only other path is via the
braid of coax back to xcvr, then back down the center conductor to the
cathode..completing the loop,
