Here's a good forum for tv antenna stuff: HDTV Technical
My AirTV dual tuner adapter picks up 67 channels and my Roku TV also picks up 67. Of course, I didn't spring for a fancy DB8E 8-element bowtie.Is the tuner in those about as good as in TV..or better, worse?
I have DB8e antenna with rotor,
You could try this:Since you guys are so knowledgeable, Peoria local channels are within <20 miles of any antennas and I pick those up with no issues with my Televes that Dish still sells. It's about 20' in the air, pointing slightly East North East at about 110 °.

Over >50 - 75 miles away to the southeast if I could reach that far, are the Champaign/Springfield/Decatur locals. I'd like to hit both using, if needed 2 Antennas combined, but trying to find that longer-range Antenna is daunting with so many out there. And how to combine 2 into one feed?

Technically YES, in actual real life, rarely. It all depends on where you live, and what directions the two antennas are aimed in, and if they have fairly tight beams. If they both receive the same station(s) it can wipe out the signal completely on that one channel at least.Wouldn't a two way coax spliter work to combine two antenna inputs?
I'm running to the TV and using the TV Tuner, but good to know!Better to use two antennas and at the TV/tuner connect them with a switch, not a combiner. The uvsj combiner us to join VHF channels with UHF channels and that is not your case.The splitter reversed as a combiner is ok for strong signals but it radiates 1/2 of each signal out the other antenna so for fringe reception it is not practical.
This presents another problem since the Dish USB tuner is not capable of adding channels with a scan with present software. Might have to play with the switch as the scan proceeds so the proper anteena is selected as the tuner scans frequencies (lots a luck).
I haven't personally tried it yet, but I read that you also need to have the same length of coax from the antennas to the combiner. There was an explanation for this requirement but I forgot it.Technically YES, in actual real life, rarely.
