Beware of Marketing Hype.
There is no such thing as an HDTV antenna, or a 4k antenna.
In fact the mileage claim is also Marketing Hype.
What matters is the quality and gain of the antenna, where you mount it, where the transmitter towers are that you're trying to receive signals from and what radio frequencies they broadcast
The recommendation came from cordcutters.com (unbiased). It's not so much the range as the direction - specifically the part about the omni directional antenna since the towers I need to hit are litterally 180 degrees apart.
ImNotSerious - I currently have an older Amazon Firestick (I got it for free). But I'm not married to it if I need to go with something else.
But back to my original problem - it looks like NOTHING can do "b" (record streaming services such as Sling, TTTV, Hulu, etc.). Which sucks big time.
Channels cannot record directly from these services, but it can record many (probably most) of the channels you receive from these services using TVE. Have you read through the TVE announcement post yet?
Sure. And you’re free to lease and use their boxes for every tv in your home.
The purpose of Channels is to reduce the need for leased hardware and alternate inputs on your TV, in order to simplify TV watching via streaming boxes that most people already have attached to their TVs. This both saves money and makes their families happy by having a modern and friendly way of watching and recording traditional TV.
It puts their live TV and recorded television right next to their Netflix and YouTube.
I think is one of the most limited TVE providers.. but it does say ESPN is supported. I think the short answer to you question is that you would be able to record any local stations you can get from an antenna, as well as a significant amount of your SlingTV lineup (although not everything). You can see which channels are supported by going directly to the channel’s own website. See if you can access a live stream using your SlingTV credentials. If so, Channels will likely be able to access and record it.
