I've always wondered if anyone actually measured and confirmed that the "static

Great question. A map showing frequency of lightning strikes shows EXTREMELY low frequency in the part of NorCal where we live, and I've never experienced that at home. My introduction to it was several years ago, during county expeditions for 7QP (Seventh Area QSO party), in a contesting trailer with no arrestors and no earth connection at all.
