Antennas have no 'awareness' of HD vs. SD, digital vs. analog.
The Winegard
HD7698P would be a combo antenna to consider. It could be paired with an Antennas Direct CPA-19 preamp kit.
As you select progressively smaller antennas, expect less gain and less opportunity for reliable reception.
In this case, there is less than 2 dB difference in performance on channel 19. But you are at the threshold were every dB counts.
