Actually, there are two main benefits to using HDHomeRun as a broadcast television channel transmitter. You might be asking, 'How is this any different from simply watching CBS, NBC, or ABC on my TV?' Because that's what I asked, at first. There is an HDHomeRun box specifically for people that have a cable subscription, but I'm focusing on people that don't pay for cable and want to watch broadcast TV on their iPhone, iPad, Mac, or Apple TV. Why would I want HDHomeRunįirst off, you're probably only going to be interested in using HDHomeRun if you are a cord cutter (if you don't have a cable subscription). With the app installed on your other devices, all you have to do is open the app, scan for your HDHomeRun, and start watching live TV. I highly recommend Channels (opens in new tab). If you want to get broadcast television on your Apple TV, you'll have to download a third-party app.

You can start watching TV on your computer right away when you download the official HDHomeRun app on your Mac or iPhone and iPad (opens in new tab). Then, using the companion app on your iPhone, iPad, or computer, you scan for local channels, just like you do when setting up broadcast television on your TV set. Then, you connect your OTA antenna to it (the antenna does not need to be connected to your TV set). Here's how it works: You connect an ethernet cable to your home's internet modem. When connected to your internet router and your OTA antenna, it makes it possible for you to watch live TV on any other device that is also using the same internet connection.

It's a box, about the size of an Apple TV, maybe a little smaller, that acts as a transmitter.
