You need an antenna, it will not DVR anything from the internet. So yes will work if you do not have internet access. I use mine on our home wifi network. So the antenna connects to AirTV box which is then connected with an ethernet cable to my wifi router, then all my devices on wifi can access the antenna. If you don't have a wifi network, your TV will need an ethernet port which many of the new ones do. I talk to mine through the SlingTV app, but there is an AirTV app for your mobile device you might be able to use. I would definitely do more research before I tried to use one without a wifi network.
