Also, in place of that, what are the results of feeding an omni-directional antenna's feed into a digital box? I tried it a long time back with an old "early stages" digital tuner, and wasn't too pleased with the results. Would I get better results now, either due to using a newer omni-directional antenna or due to using a newer box?
I'm still a bit of a newbie when it comes to outdoor antennas, but I have absorbed quite a bit of info over in our Antenna threads here
One thing I can tell you is while it's possible to combine two antennas, it is likely less of a hassle for you to use one omnidirectional (or even one directional one with a rotator). From what I understand, the coax from each of the antennas has to be identical in every way, length especially, or you'll get multipath issues, and the same goes for the combiner you use...don't go cheap on the signal combiner.
How far away from your towers are you? Your TVfool.com image/results might be helpful to post. In my own situation, my towers are grouped together in two different directions, almost 180 degrees apart.
However, I'm less than 12 miles for almost all of my towers, with the furthest stations being 45 and 60 miles away. I have a large directional antenna aimed in one direction to pull in those stations farther away, and the bonus is directly around my antenna (within 10 miles or so), it behaves multidirectionally. Therefore, I don't even have to move my antenna to pick up the stations I wanna receive, which suits me fine.
If I really wanted to, I could use my rotator to turn and scan for channels, and with my antenna being a large directional one, I could probably pick up many more stations in other markets within a 100 or more mile radius.
Hope the answer to your question(s) is in there somewhere.
