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.
