It's not much bu there have been 6 times in the 5 years that I have had an HD antenna that the cable went out or something happened where I just grabbed antenna and was able to watched what I was going to miss because it was on one of the networks (mostly sports)

I pay for cable on 3 TV's (living room, bedroom, and basement) and keep the antenna in the guest room with a roku in case anyone wants to stay in there and there's something on the networks they want to watch. And when I first got the antenna I moved into my now wife's apartment and she just had a simple cable plan that came with the unit. She got NBC but it came in kind of fuzzy so I would use the antenna to watch SNL most weeks.
