if you now don't get a picture then yes neighbour is right. I've nener got any pictures on 3 caravans I,ve had with this type of aerial 'its a 'status'. that pointed bit uscrews for travel on ferries as some deckhead sections are low and can rip it off and you can't claim.
I bought a digital aerial and mast but try local caravan dealership shop there may be attachment boxes to over come the change over without replacing the STATUS aerial
