[I realize this may not be the exact proper forum for this question...] I have an S3 that is driven by two cablecards. I also have a pixellation problem that started this summer, and I have not been able to resolve it. There are 4-5 channels that have problems, but the two that concern me the most are the HD feeds for NBC & ABC (312 & 313 ComCast Houston). With the new TV season almost upon us, I have to do something. I've tried high quality amps & splitters yada yada; I won't bore you with pixellation talk--there's a dozen other threads for that. My solution is to put up an antenna, and use that to record the HD OTA channels. This being Houston (avg elev: 12 ft; avg elev variance: 3"), antennas work well. I'm gonna clamp an antenna to the edge of the roof, run a coax to the S3, and watch my boob tube. Do I need to be concerned about lightning? We get a LOT of it here. The antenna will not be the high point on the house; it will be 12-14 off the ground, the house is 25' at its peak. And we are surrounded by a fair number of tall trees. Plus there is a utility pole with all sorts of wires on it about 15-20 feet away, around 15-20' high. Will an antenna "attract" lightning more than other objects? And is there any protection (for the S3) I should take...just in case?
