Good point for safety, year or so ago, a new ham lost his life
while putting up an antenna on the roof of a friends home,
also a new ham. The antenna contacted house power lines.

I mention this because amateur radio nearly always involves outside
antennas in urban areas close to utility power wiring on poles. The
possibility of fatal or terrible electric shock isn't confined to some
radio-electronic box interior...it exists out in the open, in plain sight.
Keep it in mind to avoid frying that mind.
