Hi All, does anyone experienced a fault of the active antenna of the GPS systems? It seems that my two antennas labelled: AeroAntenna Technology Inc AT575-109-OSRX-48-05-12-nm stopped to function after be used not for long time only sometimes. Any ideas on how check the system? The receiver seems to respond to all function WinOncore software executes... but no satellite is tracked anytime...
