The maximum range for digital antennas varies depending on the brand and power of your antenna, but in most cases, they all have a mile or less range.
For example, if you live 120 miles away from the broadcast towers then it’s highly unlikely that any type of TV antenna will work at all.
Another highly important thing to keep in mind when considering an outdoor TV antenna is signal loss over distance. When cables are run long distances the cable typically has some form of signal loss by the time it reaches your home due to splitting, weathering etc.
This is why many people experience low strength/quality signals even if their location is perfectly capable of receiving a strong signal.
