Re: analogs poor quality

So digits can do well on a "weak" signal? Cause only the analogs are snowy all others fine.

Digital will look good with a weak signal, until it gets too weak. Then it will start to pixelate or drop out completely. It's more or less a sharp cliff, whereas analog will just get snowier and snowier.

Most digital boxes can work well with the digital channel signal between -15dBmV and +15 dBmV (as long as SNR is good), just like a cable modem. That's a 30 dB dynamic range.

Many TV's start looking snowy below 0 dBmV and some start having tuner problems above +10 dBmV. That's a 10 dB dynamic range.
