Our Status 530 works perfectly on digital.
However a couple of things to bear in mind. Make sure the aerial is set correctly, either vertical or horizontal position before tuning the television. If possible as i approach a site i look at aerials on house roofs to check the setting. Caravan manufacturers are not the best people in thw world at assembling the connectors on the ends of the leads correctly. When i buy a new caravan i always check all the connections. A caravanning friend, who has sadly died, worked in the television industry and each time we met up having purchased a new caravan he would bring his soldering iron and testing equipment.Most of the faults he found were not major, but when he had finished we always had a better picture.
He was quite a bit older than me, and he used to say to me " are you watching and taking note because one day you might have to do this on your own!"
