Re: Garage door opener vs. Tesla coil

I did the same. Blew one of three or four boards. It
cost $85 to replace. As far as I know, there's not
much you can do. If you have a removable antenna
that'd be a good place to start, but your whole door
and frame are probably a giant antenna. I've turned on
my neighbor's flood lights at nearly 75 feet away, set
off battery powered alarm clocks around 25 feet away,
killed a computer PSU, and have seen wrenches on my
wooden bench arc to each other while my coil was
running ten feet away.
