There's a choke and a cap that will help keep it down -spike smoothed by choke, and eaten by cap. Same deal with 8 pin to amp except it's direct connected to +5, so what comes in gets on +5
Coax - Blitzortung or otherwise (CATV, Satellite, etc) - should go to ground block bonded to building electrical ground, and a surge suppressor can't hurt. Like this:

Same deal with the 4 pair to the preamp. Somthing like this. Be aware I've ordered one, and will be looking inside it to see if all 4 pairs have diodes and what kind. Nasty post on Amazon if it's crap.
