Typically when a receiver or other radio is destroyed it was NOT because of
a direct strike.  A strike within maybe 100 feet is enough.  There is a
_huge_ EMP field around the strike.  The field will induce large currents
in any nearby conductors.   Even if the strike is to bare Earth many feet
from the antenna the potential of the earth is raised by say 1,000 volts so
now anything connected between ground the power has 1KV across it.
