We have two points in the house where we can plug our t.vs in, to get reception. one is the one above and the other is connected to a sky satellite dish.
My question is can I change the second one to my uhf aerial onstead of it being connected to the dish. All the wiring is in the walls.
My husband said on the roof there is a box with three connections. The uhf and the dish both connect to it.
Thank you in advance for any sugestions.
