Buying an antenna optimized for digital TV reception is different than analog reception because digital signals are encoded differently than analog - a bunch of 1‘s and 0‘s versus a waveform.
As a result, the antenna design was tweaked from a rod to a wider, dish-like appearance that acts like a catcher’s mitt to the digital signal.
Not every old antenna will have to be replaced because of digital TV. Many antennas designed before digital will receive digital signals without issue, but if you experience poor digital reception then you may need to buy a different antenna to improve your reception.
