My experience: If you plug it in the wall without an antenna, you get one channel. If you buy a rabbit ears indoor antenna, you get three channels. If you buy an $85 indoor antenna that looks like a laptop, and esp. if you stick it in your window, esp. if that window faces out onto an open expanse of ground, then you can pull in nineteen channels, many of them retro. You'll have more fun with the retro and 'smaller' networks like CW which runs your local news station's 11 PM news at 10 o'clock then has sports talk from 1030 to 11.
When you discover programming like that for free, you may find that you like watching TV all year round. You don't need cable at all.
I love MeTV.
“Go to Best Buy and check out their smallest screen HDTVs.”
The nice thing about an HD signal is that it really looks better on a big screen. Even my non techie wife mentioned that she would like to move up from our 55” screen after watching a game on a front projector at a friends house.
