Radio reception?

After 'ere indoors being talked into world radio's by sales persons saying 'Yes that's the one, good clear reception' and finding they've been crap for clear BBC reception in France.
I propose fitting subject to replies the following.
Radio (car type)
Connection via small sat dish aerial.
Do I also need a satelite receiver? (Ouch! £99)
I do have a freeserve box for TV will this do?.
