Here on Guam, we get more than 90 inches of rain annually. I have found
that it is impossible to keep water out of enclosures, and if drain
holes are drilled into the bottom, ants and other jungle critters will
move in with dirt, ETC, that cause the same problems as a flooded box.
For me, what works best for my simple transformers (nothing requiring
power) is to use a small Radio Shack or similar plastic enclosure with
the lid off. The enclosure serves to mechanically hold and protect the
transformer in place. I do seal the underside of the RG6 bulkhead
connector with RTV sealant to protect against moisture ingression into
the coax. The whole thing is covered with a cut-off water bottle to
keep direct rain off the transformer.
This idea may not sit well with perfectionists, however it works fine
for my purpose.
