How do I get NBC on my antenna?
Watch NBC Live for free with a TV Antenna
If you have a TV antenna handy, but haven't used it in a while, plug it into your television's coax port and scan for channels. People living within 30 to 40 miles of local broadcast towers have an excellent shot at getting local broadcast channels with a quality TV antenna.
With a TV antenna, you can potentially get the big four broadcast networks, ABC, CBS, FOX and NBC. There are a variety of other local networks available for free on over-the-air channels such as local PBS affiliates and The CW Network.
But no, NBC isn't doing anything as a network to intentionally prevent access. I will say that most indoor antennas struggle with VHF signals, so if you're using an indoor antenna, and you find your local NBC is broadcasting on VHF, that is likely the root of your problem.
To begin, you must purchase an antenna capable of receiving both VHF and UHF signals. This is critical because older antennas, including those marketed as HD digital antennas, can only receive UHF signals. This is one of the most common reasons why your antenna is unable to receive the CBS channel.
Using your TV remote, access the Smart Hub. Select Apps, then use the magnifying glass icon to search for "NBC" Click through the prompts to install the app, then click to launch.
Let's take a look at DIRECTV STREAM, Hulu + Live TV, fuboTV, Sling TV, and YouTube TV, all of which include NBC in their live TV channel lineup. Hulu + Live TV is, as you may expect, the skinny bundle service from Hulu, a company once focused entirely on on-demand streaming.
Also, most problems that cause NBC live stream not to work can be solved by re-linking your TV provider every month. You can do that by going to settings, unlinking your current TV provider, restarting the application, and linking your TV provider again.
In general, though, setting your TV's input to "TV" and flipping through channels should do the trick. If you know your local channels' exact numbers, try navigating to one of them with your TV's input set to "TV".
How does Over The Air TV work? Major networks including ABC, CBS, NBC, FOX, and PBS have affiliates in almost every major US city that insert local programming into the network's national feed then broadcast TV signals over-the-air from a centrally located broadcast tower.

Why is my antenna not picking up channels?
The signal could be lost in the coaxial cable distribution.
If you are using a splitter, this could also weaken signal strength. Try disconnecting the splitter and running the cable directly into the TV/converter box and run a channel scan. If reception improves, a distribution amplifier is likely to be the solution.
The straightforward answer is, in most cases, the antenna you're currently using may be unable to receive a CBS signal. On the other hand, the long answer means that you might need a little refresher on the TV broadcasting technology you use.
