[TowerTalk] Sealed container needed for tuner

[chas]

I want to mount an SGC-239 tuner on the tower below a vertical.  but I need a
UV proof, sealed, water tight container that I can put the tuner inside - and
then put that tuner in a tupperware? into another container if it can be
found.   And all of this as cheap as possible.

I think that NMEA cases are just too expensive but that might have to be the
end choice.

thanks
