I have a Dec 2017 Kadjar and I also have problems with the DAB radio losing the signal. I (try to) listen to Classic FM in the East Devon area and I have to say that this is the worst radio I have ever had in a car in nearly 60 years of motoring. Not only does the DAB signal disappear but the FM signal for the same station does exactly the same! I ran several Land Rover Discoverys and Freelanders in this area for the 20 years prior to buying this car and all those radios (FM) worked perfectly. I have now given up listening to this rubbish piece of equipment and have a memory stick with my CDs on it. This is a pity because I like the car just wish they had put in a decent radio that actually picked up a radio signal!
