[Elecraft] Whole house surge protector at the main breaker?

[Walter Underwood]

When I was in high school in Indianapolis, our next door neighbor was a ham. He worked on lightning arrestors at GE. He said that the impedance of a ground strap was too high for a lightning pulse. The lightning would use it as a guide, jumping between the strap and the guide. Until it got close to ground, then it went everywhere.

So don’t assume that lightning follows the rules you know about DC or AC power.

But by the damage I'm sure to surge was on the phone line not power line. That was based on where the shorted protection diodes were.Would I have lost anything else had the LA302 not been there is unknown.  Neighbor lost the control board on a dishwasher.
