Ok, I have a DTV with no hi def locals (waiting on HR20); I get all my locals via OTA through my HR10 except the one (CBS) my favorite team will play on Sundays. Interestingly enough, if I plug my Antenna cable directly into my TV this channel comes in, (my HR10 OTA tuner shows about a 16- 20 signal strength on the HR10 but seems to come in ok in my limited testing on my Sony KDFE50A10 50 built in tuner though I would love to know what the differential is as to how strong the signal is on my TV). So my question is what would be the best way to split the signal so I can run a line from my antenna directly into my TV AND my HR10 so I can record the locals I do get? Will this effect my overall signal strength? Do standard cable splitters work here? Can I put a signal booster inline without getting on the roof? I don’t want to go crazy because the HR20 is around the corner, but don’t mind spending a few bucks to alleviate the aggravation of watching my team in SD and switching cables between commercials. Thanks in advance!
