Anyone any experience of separating the top from the bottom of the dome. Have had an intermittent fault on tv, traced it to the coax connection to the antenna in the dome. Taken the antenna off the roof to remake the connection, but can't see a way of separating the top from the bottom of the dome to facilitate repair. The only method I can see is 'brute' force to separate them. But don't want to use that, only as last resort. Anyone had experience of working on one of these and separating the dome. (Have contacted Vision Plus - manufacturers, but don't know if they'll get back to me. Have informed them the van is only 18 months old. -warranty- I think. But away again next week so want it repaired for then) Any help would be appreciated.
