Oh no! Not again!
We've had countless posts like yours over the past decade or so. The product name keeps changing but, when you examine it, it's the same ruddy thing every time!
In many parts of the USA it's the norm to have cable TV or satellite TV, rather than to receive channels from transmitters beaming out radio waves (as is the norm in the UK). So a US manufacturer has produced an indoor aerial with an amplifier built into it and has then started marketing it as a 'wonder product' which can receive the US equivalent of Freeview, telling gullible Americans that purchasing one of those aerials will enable them to cancel their cable and/or satellite subscriptions and still be able to watch many prime channels.
The manufacturer (or, more usually, a franchised distributor) then tries to expand their sales base by offering the same product in the UK, again with the promise that people can ditch their satellite or cable subscriptions. (i.e. what they're actually saying is "You don't need Sky or Virgin Media to watch BBC channels, or ITV or Dave, Drama, etc. You can just watch Freeview instead by using one of our super-duper aerials).
The product CAN'T receive any TV channels that a normal Freeview aerial can. Given that the Freeview signal isn't strong enough for indoor reception in many parts of the country, it might well NOT pick up any channels at all!.
AVOID! AVOID! AVOID!
