As to the "digital" antenna "claim" I'm thinking the seller is just saying that his offering will capture the .1 sub channels and labeling that "digital". Meaning, IF anyone could even pull in an OTA (over the air) signal your TV (if tuner equipped) would present, say channel 10 (Wavy) as 10.1, 10.2, or even a 10.3.
But, as anyone trying this knows, as Tim advises, unless you have a 300 foot tower, you ain't getting squat beyond a few super weird "local" channels.
