My daughter has a Lexcom system in her house in the UK. Although she doesn't have them, I notice that you can get powerlink and masterlink modules fitted within it.
For those not familiar with this type of system, the whole house is flooded with sockets which look like UK phone sockets. All these sockets are wired back to the Lexcom which is actually just a patch system. Thus, any socket in the house can perform any function, including the RF for the tv aerial. Quite clever.
She asked me to put an aerial socket in the grand kids bedroom, so I went over armed with a reel of coax, sockets, drill and all the rest of the stuff. What are you going to do with that Dad, says Lauren. You only need to connect it in that box thingy in the wardrobe!
