By combining the signal from multiple antennas in the analog RF domain, you are creating an antenna array. I believe there is plenty of voodoo that goes into making antenna arrays. I know a little about RF arrays (from MRI), and I understand a tiny bit about phased arrays. But designing an antenna array for a specific purpose requires a lot of knowledge ... I could probably do it after a couple of years of study, but I'm not going back to school.

However, combining antennas using two tuners just requires that the antennas be far enough apart on the roof that they are not electrically coupled by their proximity. Then each tuner decodes only the signal from a single antenna, and there is no mixing in the analog domain. The choice of which program you want is done in the digital domain (on the HTPC).
