I bought this from Chris at CCA a couple of weeks ago,Cost £60.It basically boosts video signal so you can run 3 screens without any signal loss.It has 2 inputs and 6 outputs.Its unused as I bought a second dvbt tuner that has 4 rca outputs on it.£40 if anyone on here wants it before it goes on the bay I also have a DVBT tuner but its crap on the move,perfect if you just want to watch whilst parked whilst being dads taxi,this has the original ariel and an active ariel (also from CCA)Cost of those was £75,if you fancy having cheap tv in your car you can have the lot for £70 posted.
