Hi David,
Depending on the size of antennas, weather conditions, rain, snow, wind etc.
charges up to 100's of volts can build up on antennas. This is why some
brands of lightning arrestors have a high resistance bleed resistor
connected across the coax connector on the antenna side of the arrestors to
keep this potential from building.
It is possible this potential is what killed your preamp.
