Multiples of same
 

I used the tool to get a list of channels we can expect when we switch from direct tv to a rooftop antenna.

It looks like we'll get oodles of channels. However, it looks like we'll get 8 different PBS channels, 6 different ABC channels, 5 of fox, etc.

How will I know what's on or is going to be on these stations?

There are a variety of online television program guides.
