Thats what I am considering as the first option. It certainly would be
quicker / easier.
This depends a lot on your soil conductivity. Wiring under the house
is likely to be partly shielded by the house 'earth'. 100 ft is quite a
long external 'aerial'.
It may be less depending on where I decide to place it.

It is. I have experience with the "ground" effects of lightning. We had
a ground strike to the metal reinforcement in a runway at an airport I
used to work with, it took out about half of our runway light system
with it. We knew it hit the runway by the damage on it.
