"As mentioned on this site i have put a 32 inch aerial on the car which helps, but you can get fibre glass v long wips meant for Scooters, i am thinking to put a 4Ft 6 inch aerial on the rear roof.Rgds Mike"

If you want better reception why don't you listen to the internet stream or move permanarely to Suffolk?
