Hi chaps very new to all this just registered... I'm having v+ installed Saturday in my newly decorated front room. Iwanted to have the box under the stairs wher the modem, phone and all arieal sockest are. A friend of mine mentioned "Goblins" to change channel.

What are they, will they work will the installer have them on the van, how much are they. If there not on the van where can I get them??

Thanks in advance
