We've just moved into a house which we're renting. There's an aerial on the house roof and a Sky dish on a ground floor back roof. The Sky dish is wired through to the front living room. The other aerial seems to have connections for 2 bedrooms upstairs, so nothing in the living rooms downstairs. I assume the dish is remotely disconnected as we're not paying for Sky TV. The inventory isn't very detailed and doesn't mention anything about aerials.How do we use a TV downstairs, keeping in mind that it's a rented house and we're not allowed to add anything, not even a nail on a wall, and we don't have much idea if it involves adding wires and doing anything complicated! Thank you.
