Digital Converter Box
I just recently purchased 2 of the digital converter boxes for our over the air signal for out TV's. We presently have 3 TV's that we use on a regular basis at our household. Probably the biggest difference one notices right off hand is the signal the TV receives. It is much crisper and uniform generally. Two of the TV's have the converter box attached. The one TV without the converter box will still be able to pick up the analog signals after the switch over because not all TV stations have to switch over.
Also another great feature of the Converter Boxes we purchased was the fact that our HD Ready TV now has a tuner which receives the local signal and shows 1080i signals (HD). We kind of got burned when we bought our TV back a few years ago. There are two different kinds of digital Tuners. This TV had the wrong one, so come the switch, we wouldn't have gotten a signal on our digital TV even though it had a digital tuner in it. I had read where the over the air broadcast HD signal is better than Satelite HD signal.
I would say its as good, at least here locally. and It don't cost us a dime. I am very thankful for that.
