I swear to god this is just making me considering buying an hoping I get reception in my apartment so I can just drop the cable streaming all together.
I have an indoor antenna and I get 30+ channels (some of those are the same network).
It took 2 days of trial and error positioning in order for it to work for me. Positioning the antenna near a large window / sliding glass door is generally necessary for it to work. It's best to search the internet for over the air tv distances and positions from you before you start so you know what channels you might get.
Besides the antenna, I get Sling Blue TV streaming ($25.00) which gives me access to most of the cable channels I want (not interested in Disney, ESPN although I wish I got FOX business / FOX news).
