I bought one of these and plugged it in between the tv and the aerial socket in the wall. Its stopped nearly all the tv channels going through. Is there a problem with the device or could it be my aerial input. ( i live in a flat and have shared aerial)

Unfortunately we are unable to guarantee full compatibility for this item in your intended application, This should not have a large effect on the list of stations you can get unless you already have very poor signal.
