that's cool......very nice of you to buy and set up the antenna for your relative.
someone needs to make our smart phones or hand-held devices with the ability to receive over the air TV. I do miss lugging around my old 5" portable Panasonic TV screen packed with 8 D cells to football games to watch the game while being at the game (then replaced by the Sony Watchman).
But of the 50+ channels I get in the garage, like you, many of the free channels are Chinese, Korean,. Espanol or infomercials......
But I do get the major networks. (ABC, NBC, CBS, FOX, PBS, etc.) ....... NBA finals on ABC this week..... I may just pipe an extra TV for the patio soon.
with Apple TV , i'm set.......for the past 2 years, I have order NFL league pass to watch the Ram games on delay.... it's not the same as Sunday Tix, but it saves me $400 a season.
