You can also help mitigate lightning ingress to your equipment by grounding the coax right outside the house.
I carefully cut away about a 1/2" of the coax casing covering the braid, just before it enters the house, and attached & soldered a ground strap from it to my ground rod.
Just be careful not to get it too hot and melt the dielectric insulation between the coax braid and center conductor.
I resealed mine by applying "Liquid Electrical Tape" in a small 4oz metal can.
