As the owner of a DB8e, I'm impressed by it, though my mounting is not finalized. It's a UHF-only antenna. I understand its advantage is that is a newer design, targeted to the narrower bandwidth 14-51 since the FCC turned over 51-69 to other uses than TV. Older designs target 14-69. It's directional, but you can aim each array in a different direction. Typically the more directional and the smaller the bandwidth, the better the reception.

I've been observing advice here for a while, am a technically savvy guy, and have observed that generally you look at which channels you want to receive, and which band they fall into - VHF low, VHF high, or UHF. Typically you aim for the clusters of available stations, yours being at about 63 and 230 magnetic. If there is a particular station you really want, you can erect a targeted dedicated antenna, and either mix the signals (VHF-UHF combiner) or bring each antenna feed to a separate tuner, and provide both feeds via a PC or some similar device. So look at what's in the air, and what you might might want to bring in. The weaker the signal, the less certain that you can receive it, even with appropriate measures.
