The idea of using a cantenna for audio is new to me.

I would be inclined to use distilled water for continuous use and tap
water if use is intermittent. Cheap & trivial risks!

As I think back of all the lash ups I have used to build and test
power supplies through the years I think you have led me to a much
more practical solution!
