Hi guy's need your help, washed the van today( roof as well) when up there i noticed the aerial saucer bit was a bit wobbly so i got hold of it and it just lifted off and was full of water any idea how to get rid of the water and how does it fix to the mounting bracket, have put some gaffer tape on for now might be a warranty job but don't know how long before i can get hold of dealer, thing is do i fix it now or wait
