I ended up returning my Terk HDTVa, and am deciding whether I should get the CM 4030, the Terrestrial Digital DB2, and the CM 4220. Honestly, I'm guessing that the CM 4030 isn't too great, seeing that there are nearly zero reviews for it. So I think my top choices out of the three are the DB2 and CM 4220, but they're only UHF. Is there a 2-bay antenna that's both UHF and VHF?

Actually, I'm going to choose between those two: the DB2 or the CM 4220. Generally speaking, the DB2 seems to be a bit more expensive, but does that mean it is better? I mean, they're pretty much identical in all aspects..

Please post your antennaweb results, hard to recommend an antenna not knowing your requirements.

On the antenna thread, I gave you this link?

The CM 40x0 series are rabbit ear VHF and loop UHF antennas with impedence matching (the dial) and a not-very-helpful amp. They are unlikely to outperform your Silver Sensor.
