I have a new 2009 caravan with adjustable arial from inside the van. I also have a brand new Digital T.V.However,on site im not picking up any stations. I also bought a signal finder but it has made no difference reception is still virtualy non existant and the signal finder says no signal.It has been suggested to me to go to Maplins and buy there Satellite free sat in a box system for caravanners it costs £99.99.Im told its easy to set up is this correct? it works every time? and it will recieve about 80 channels? I will spend the money if its an easy and successfull fix? but really dont want to waste money.Can you advise please.
