My sailboats always had relatively small metal antennas at the top of the mast, but my trawler has a couple large fiberglass antennas. As I understand it, after 10 years or so, the sun's UV radiation does enough damage that the antennas need to be replaced. My question is: are you replacing the antenna because the fiberglass looks awful, or because the UV radiation somehow limits the antenna's ability to transmit and receive? Also, is there some way to determine when it is replacement time?
