Being a bit of an old fart and because I use smart tv's normally so have never tried anything other than the usual Sky and BT boxes, I have no experience of the "sticks" and "boxes" on offer, so I need what is probably very basic advice/help. In one of our rooms I want to set up a spare TV (not smart). But there is no aerial outlet, and portable aerials do not provide a stable enough picture of the normal terrestrial stations - have tried auto tune and manual tuning - but no good. But there is a good broadband wifi signal there. So my question is, would something like Roku or Amazon Fire stick enable the tv to show the normal terrestrial channels in a convenient manner (like a normal TV), changing channels etc, via a remote preferably - or not.
