From: James on 5 Jul 2008 08:31 Do some boxes get better reception than others? I wonder if a more expensive box gets better results than the cheap one from Walmart.

The processing of the video information is where quality differences would lie. That is, one box might OUTPUT better quality picture than another. BUT, these boxes are meant to be used on older analog television sets. If there is a difference in video quality from one DTV converter box to another, it will not be noticeable when the monitor being used is analog. -Dave

There are differences between the performance of digital tuners built into different digital TVs and ATSC PC tuner cards. In some cases, different tuners running side-by-side from the same signal input can have significantly different performance. True, once locked on a signal the pictures are the same, but one may hold a given (marginal) station better, with fewer dropouts and glitches, than the other. I don't see why it would be any different with convertor boxes. Dennis (evil) -- What government gives, it must first take away.

I've tried Zenith, Magnavox and Dish (DTVPal) boxes and both picture quality and number of stations recieved varies significantly. The difference is noticeable even on a 20" Sony TV. The Zenith picture quality and reception is far better than the other two, the Dish has the poorest reception. Picture qulity between the Magnavox and Dish is about equal. GordonD |
