The moral of the story is "use red boxes instead of black to house matching
and reflection transformers for beverage antennas";-).
While the odds of a plastic box being conductive are fairly small, our
expereince shows that it can obviously happen. It's entirely possible that
the pigment used to color plastic could be a conductive material such as
carbon!

I can only agree on that!
FOR WAE SSB 2005 at DF0CG/DR1A I installed two 80m halfsquares at 90° two
each other with a matching network and direction switch.
A coil, vacuum variable and vacuum relay went into a large black plastic
box.
Look what has been left next morning:
