What is the main cause of failure with marine antennas?
A. Water entry: either by storing the antenna upside-down and allowing standing water to creep in, or by water creeping up the coax cable through capillary action. Quality marine antennas are usually well sealed and injected with poly-urethane foam but standing water in the mounting flange can creep inside over time. Lightning also damages a few antennas every year. Good marine antennas have a static discharge protection circuit but it will not protect from a direct lightning hit. Warranty does not cover damages from Lightning or Water entry.
