We are talking about 200kHz here not 200MHz!! Use could join the coax
with a bit of choc-block at that frequency and not see any significant
performance degradation.

It doesn't matter if it's 200kHz. The problem remains.

And yes, there WOULD be s"significant performance degradation" if he
used a bit of choc-block.

But if you understood ANYTHING about transmission lines, you wouldn't
make such a stupid statement.
