As Tyler covers in his video, this has been tried many times before. All such efforts end in bankruptcy.
First, understand this in NOT about paying for current OTA TV, either the big networks (CBS, NBC, etc.) nor the current "netlet" rerun channels (Decades, Antenna TV, etc.). It is about replacing some of those "netlet" channels with scrambled signals of channels traditionally found on cable, DBS, and linear TV cord switching providers.
If you go to their page, its 30 ish channels, many of them things that are super niche. Stuff like the Cowboy Channel, World Fishing Network, and Recipe TV. Only Root (the local RSN in that area) NFL Network and the Weather Channel are what I would consider even close to mainstream channels, and that is being generous.
For $34/month? Pluto and STIRR are free.
And, of course, you have to live in the OTA range of EVERY channel, including LPTV, in a market to get this to work fully. That is not really that many people, and most people that live that close to town, have good internet.
