Actually, you guys helped quite a bit.
We suffered a lightning strike to a tree earlier this spring, just feet from the deck where this weather station will go.
It blew a strip of bark completely over the house and onto the front sidewalk, a good 25 yards away from the tree.
We were sitting in the dining room on the other side of the patio doors from the deck and tree when it hit. To say a fresh change of underwear was required is an understatement.
Roberta X even drew me up a schematic showing multiple MOVs, gas discharge tube devices, and induction coils in the circuit to create a layered, sacrificial defense.
Her biggest caveat, which sunk in to me, was that if the mast took a "once in a blue moon" hit, none of those things would prevent my household wiring from getting zorched.
I don't need to set my house on fire for the sake of a pretty red beacon on my weather station.
