Winegard RCDT09A

In terms of performance, the Winegard RCDT09A is rather mundane, finishing in the middle of the pack in most regards. However, its ability to draw power from either an optional battery pack (*est. $15) or an optional cigarette-lighter adapter (*est. $15) is unique. That makes the RCDT09A an ideal -- and currently only -- choice for those who want a digital converter box for an RV or motor home, or for camping, tailgating or just watching some TV in the back yard. It's also the only converter that will let you use an older portable TV in an emergency if the electricity should go out. If you don't need or want portable operation, other digital TV converters, such as the Zenith DTT901 (*est. $60), are better performers and a touch cheaper.

There isn't extensive feedback on the Winegard RCDT09A, but what's there is pretty good. CNet.com has the most extensive review. The Winegard RCDT09A is also included in Consumer Report's encyclopedic roundup of converters, though we wish the discussion was more complete. User discussion is more limited for this digital TV converter than some other models, but a handful of reports can be read at Amazon.com.
