      Very interesting!  What happens is water condenses inside the element.
 Since water vapor is pretty small, it'll get inside under the right
conditions.  Then it collects into drops and - guess what? - the drops are
too big to drain out of the element.

      The same thing happens with antenna booms.  Many times I've slung an
antenna to lower it down and one end of the boom tips way down.  You re-sling
it, the water sloshes to the other end and it tips the other way.  Argh!  If
you remember, drill a weep hole in those rubber end caps on the boom and
you'll prevent this annoying problem.
