How will I know which channels I will get with n antenna vs cable? Can I get Netflix? How about NESN? I live in New England in a house surrounded by trees. I want to cut my cable bill but want to undertand what channels I get first.
You can't get Netflix over the air, you need Internet access for that (whether as a part of cable package, or not).. And you'll need either a Smart TV for that, or another smart device (DVD/BD player, laptop/desktop etc).
You won't get HBO, Stars etc either, so be careful with cutting. After you see what over-the-air channels you can get (and what antennae you need), you might check sites like Hulu, Sling to stream some of the missing channels over the Internet.
