The forum descriptions basically say that this is the place for stupid questions, so here goes. I currently have analog cable thru the local cable company and recently bought an HDTV-ready set. I'm really anxious to get some HDTV programming, but I don't want to sign up for digital cable or E* or D* until there is more HD content available. So, I picked up an OTA HDTV tuner (Sammy t151) off of ebay and it should be here anyday now. I'm hoping to be able to use an indoor antenna, but I'm skeptical. My question is, assuming I need to put an antenna on the roof, what is the best way to run the cable? Down the side of the house and into the crawlspace (if so, how do I run it back out of the crawl space to the TV)? Down through the roof and ceiling somehow? Down the side of the house nearest the TV and then through the outer wall? We just moved into a new house in a nice neighborhood, so I'd like it to look as clean as possible. Can I run the antenna cable down to where the analog cable from the cable company comes in, and combine the signals, then separate again when it comes out of the wall behind the TV? Is this something I can do myself or should I have it installed? How much will an installation cost? TIA.
