[amsat-bb] Waterproof mast mounted preamp enclosure?

Looking to move my two mast mounted preamps into an enclosure. Who knows of a good mast mounted waterproof enclosure that will handle 2 Advanced Recv'r 160 Watt Mast Mounted Amateur Preamp's inside? The preamps are 5" wide and 2-1/2 deep. I could stack them on top of each other or side by side. Let me know if the suggested enclosure will have the hardware to mount to the mast. Provide me with links to the items.

Thanks. Steve NS3L
