sorry for asking lots of basic questions but the documentation for this van is sparse. There is a TV Aerial socket in the cupboard meant for a flat screen TV. In the sales brochure this is described as a "TV antenna socket with wire". So does this mean there is a wire loop type aerial buried in the walls / roof of the van, or is there a wire hidden somewhere to attach an aerial to? If so - where is that wire! I have tried a TV when the van is parked up at home in a reasonably strong signal area and it does pick up freeview reasonably well which made me wonder if it is just a loop in the roof.
