Adding antenna channels to Channels DVR

I have read that if a TV was manufactured after 2007, it has a built in TV Tuner. I want to add an external antenna to my TV to get some local channels that are not provided by Spectrum. I have previously added an external antenna to my TV and was able to get about 50 channels. Will my Channels DVR let me add these channels directly from my TV or do I need an independent tuner such as the HDHomeRun? I'm new to using Channels DVR and I am just a little confused on how to add additional channels and services to my DVR. Any help appreciated!

No, you cannot use the TV's tuner. You will need a separate HDHR tuner.

Channels has no way to access the channels tuned with your TV's tuner. You need to use an HDHomeRun. Your antenna attaches to it instead, and Channels communicates with the HDHomeRun over your network.
