There is no such thing as an antenna designed for digital TV just like there were no antennas designed for colour TV. Anything a company tells you will be to sell their product. I spent many years in the radio/TV servicing game and the money made flogging colour TV antennas in the seventies to naive customers was astounding. What does get up my nose is the way digital is portrayed as something wonderful - any fool can see that it is hopeless when interference is around. An analog TV by its very nature will mask noise and weak signals (within limits) whereas a digital TV goes stupid with pops and sqeaks and blocky pictures with low levels of interference. And they compress the hell out of the signal giving rise to 'onion ring' effects in dark scenes and crap pictures during scenes with fast movement.
