Updated August 16, 2017 to add our review of the Terk Trinity Xtend indoor TV antenna, which also includes an 802.11n Wi-Fi range extender. We weren't impressed.
Ditching your cable- or satellite-TV subscription and going to a setup combining a streaming device along with an antenna to pick up over-the-air digital broadcasts is a smart move that will save you some serious cash every month.
There’s plenty of free TV to be had—well, you’ll passively pay by being exposed to commercials—but you’ll need an antenna to pull those signals in. An outdoor model mounted to a tall mast (elevating the antenna at least 30 feet off the ground) will yield the best results, but that’s not the most attractive accessory for your home, and it’s a total no-go if you’re a renter or live in an apartment.
