Im absolutely hopeless at this tv stuff I dont understand it in the slightest

Basically I have a dish down the end of the garden its dead as far as I know the wiring does nothing

I have upc downstairs but they want 50e per room to connect us upstairs screw that il eventually be ditching them altogether

Im looking to get bbc e4 channel 4 etc into the bedroom as cheap as possible what do I need lads
?

A freeview box and some cable to run from the dish will that do
