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.
