Amazon announced a new Fire TV Recast today. It’s a box that can beam shows from an antenna to your device through Fire TV. All you need to do is place the box in your home, and start streaming on your Echo Show, Spot, Fire TV, or on mobile.

A feature in the app will help you determine where to put your antenna for the strongest signal. Fire TV Recast can be integrated into the channel guide, so you could watch with Prime Video and even PlayStation Vue. You can also watch local news and shows from channels like ABC, The CW, and NBC.
