Check all coax connections , look inside the connectors on the ends of the coax for corrosion. Also look inside the connectors to see if the foil shied and shied wires of the coax is pushed in toward the center wire of the coax , if is , then push foil shied and shield wires away from the center wire with the point of a knife or small flat blade screw driver. If water has entered in to the coax then put the coax in the trash.
