Got hit by lightning a month ago,lots of things happened after that.One electronic phone was fried,blew out the hdmi port on my geo sat pro,but not the av port,fried my direct tv receiver.Some how the dish moved locations.At first though it cooked the lnbf,changed it out,moved the dish and it worked again,so don't know for sure if it fried the lnbf.On my other 10ft dish,it changed all my sat locations on my mover.?????Since then I've grounded all the coaxs,don't know if it will help,guess it couldn't hurt.If lightning heads my way now I unplug and disconnect the coaxs.Also gonna put everything on surge protecrors,figure it might help.It was a major pain in the arse.
