It really sounds like water in the feedline issue.? Fiberglass antennas are not for repeater use…but we do what we have to.? Fiberglass bends with the winds and creates micro-cracks over time…resulting in “crackling”.? One could replace a fiberglass antenna several times over the years before the cost becomes greater than that of a nice Decibal Products antenna.? Are you running digital and is the PA compatible with digital?? Did it every work correctly?? Attach photos of your setup…repeater, cans, antenna, feedlines, jumpers, etc…maybe someone will spot something.
