How good is over-the-air digital reception?
In the analog era of OTA signals, snowy and blurry pictures were not uncommon. Digital changed all that. Now, if you get signal, you get excellent picture quality, better than many other video sources. Data compression is used by cable and satellite providers. This allows them to offer you many channels but the compression will result in compromised picture quality. Off-air antenna reception is the best way to enjoy digital programs at the full resolution the TV networks intended since no compression of signal occurs prior to you receiving it.
