Well, I can certainly imagine being zapped by high RF voltages!

Of course, that's not the real subject of this thread, but it's
certainly a reasonable practical consideration.

I wonder, if there's a solid material, suitable for construction of an
enclosure, whose electrical properties are more similar to that of air
than those of metal or wood?

========================

If you insist on an enclosure, next to wind, why not try glass?

Then you can view the roller and capacitor settings without the
inconvenience of taking all the screws out of the cover. It's also easy to
show a next door neighbour the works, calm him down, just after you've
cleared his TVI.

There's only roughly 1000 volts, its RF not DC, around a 1 KW tuner. Fairly
harmless stuff. You can't call yourself a real ham unless you've ever had to
quickly remove the tip of your forefinger from a hot spot.

But don't make a habit of kissing capacitor vanes, attractive as they are,
because they look beautiful in motion!
