this can happen.if you suspect it has....remove the chrome tower where the whip insets(it screws off)let air dry a good 24 hours ...then add silicone or some other sealing agent and reassemble.
we are getting to the problem.

ok .....heres the problem.
see this nut.
By null at 2008-02-09
it was loose.causing the stem to rock back n forth making the swr jump around.make n break the connection so to speak.
had this mag mount been designed in a way as to access the insides without trashing it this could have been cleaned ,tightened and put back in service .
look at the corrosion ,this nut was loose

what you are going to see now is where the coax feed is soldered to the coil,
you could actually unsolder this and by moving it around on the coil you could tune this antenna by hand for different bands ,or make up for too short or too long of whips .
look......
