I forget where I saw the photograph but it showed the most beautiful Rockmite based rig in a blue waterproof plastic enclosure. It was as much art or jewellery as it was radio engineering.
I found these transparent plastic waterproof boxes in the Decathlon store today. Decathlon has stores across EU and they also sell via the internet. If we have a radio constructor/ artist/ jeweller on board, maybe this will be useful info.
