I have recently bought a Panasonic TV with integral HD freeview. I also have a Thompson top up TV which I want to use as i subscribe to Sky Sports. How to use both - clearly if the aerial goes into the box there is no reception via the integral tuner, and vice versa. Both the box and TV connect to a Sony AV amp, one by Scart and one by optical. Would a simple aerial splitter , or an amplifier with splitter allow me to switch between tuners depending on what I wanted to watch ?
