Thank you so much ... Frank and Remco.
I have ordered what I 'think' is the full Monty from Rene - including the waterproof box.
I think that the special transverter may have been for Wolfgang HB9RYZ but I am not sure!
Since the feed and the transverter both use N-type connectors, I will use Ecoflex 15+ and keep the run as short as I can. It all depends on where I have to put the dish in order to 'see' the satellite. It should not have to be more than ten metres I think!
