I spent most of the 90's living on the West Coast (in between Southern California and British Columbia) and in all that time saw exactly ONE storm with lightning. It was a memorable event but is nothing compared to where I live now, where electricity or phone service is off several times a month for several hours at a time as a result of storms (storms winds taking down trees taking down the wires, or winds/trees causing 120VAC or even worse 480 three phase to appear on the phone lines as a result of a line cross, or direct lightning hits). A few times it took a whole week to get electricity back. This is not in the middle of nowhere - it's literally just a few miles from Washington DC. I grew up in the midwest and it's nice to be back where there are thunderstorms again. > I can only recommend appropriate surge suppressors for the antennas - even > if this means a couple of dB's attenuation.
