"It's like a router for free TV."

AirTV aims to make antenna TV easier, more mobile for $120. But to do it right requires extra gear. Unless you already have an antenna setup, you'll need one for every TV in the house, and some of those TVs may be in rooms without good reception. Unlike streaming services, you can't watch antenna TV on your phone, and you can't pause it or record it to a DVR. And the interface is nonexistent or archaic at best. AirTV is $120 box made by a subsidiary of satellite broadcaster Dish Network, which also owns the Sling TV service. AirTV connects to a single antenna and delivers free broadcast TV from that antenna pretty much anywhere you want. So why would you pay $120 for over-the-air TV, something you already get for free? Convenience. Here are its main capabilities. Two tuners, so you can watch two different channels on different devices simultaneously. One tuner can be watched outside the home, for example streamed to a phone, anywhere in the world. Connects and streams using your home (wired or Wi-Fi) network. No monthly charge for program guide data. DVR capability, via a connected hard drive or USB stick, coming later this year Watch on a TV, phone or tablet via the Sling TV or AirTV app (no Sling subscription required).
