Are you talking about a terrestrial freeview box (that you just plug into your aerial socket and then into the TV?)
Do you have a reasonable reception currently on your TV in Scalea when it is simply connected to the aerial?
In principle the box should work as it will scan for DVB-T channels but it would be dependent on signal strength. I've checked for coverage at this site but it tells me we have 50% coverage in our comune and I can't find any coverage at all for Scalea.

Having said that, if the box is small enough to pack in your case maybe you should just bring it and have a fiddle when you get here to see if it works?
Hope this is helpful, Lesley
