Digital Signals

The statements about "digitally tuned" and similar comments are pure nonsense as the ATSC OTA signals are analog until converted to digital in the demodulator inside the ATSC tuner. RCA does not need anyone's' permission to sell Yagi antennas that have been around for over half a century. If that is not true, let's see a Patent number.
A true digital signal cannot be amplified by an analog device such as an antenna preamp or amplifiers in the front end or RF receivers nor by an LNA on satellite dish horns. The true digital signal is at the input to the modulator and the output of the demodulator. If one is into splitting hairs, the ATSC signal as well as those used by Dish Network and DirecTV and other satellite as providers as well as ATSC are actually considered quasi-analog because they do not meet the definition precisely as having an infinite amount of signal resolution
