Now that I have gotten hooked with the HTPC bug, I've been thinking about either adding one of the HD tuners or upgrading my DISH to HDTV. My question, before I spend $400 on a card, is how far can I expect to get off-air reception? I am about 45 miles from the Boston transmitters. Is it reasonable to expect acceptable reception from this distance, or should I just stick to the satellite? A roof or attic mounted antenna is not an obstacle.
