 Is the coax connection water proof?   Water can wick down a coax
line.      What kind of connections are they?  BNC is not water proof.
 I think you said a plastic bag was used.   Then you'd have humidity
sealed in.    When in the sun the water turns to vapor and can get
inside then it cools and the vapor condenses to water.  Happens one
cycle per day.  It is better to use an inverted jar that is open at
the bottom than a sealed bag.   The best setup is to buy a real timing
antenna.   These are 100% sealed and the connection between cable and
antenna is inside a 3/4" iron pipe.     Such antenna are not
expensive, on eBay, under $30.
