I installed a new Garmin GNC355 GPS with a new CI-2480-200 dual com/gps antenna. The GPS acquires satellites fine but during flight I get a LOI warning and loose the GPS. It also says can’t find satellites. At times in landing phase the gps will go back on line. I have been troubleshooting this with the avionics shop that did the install but no luck. It’s very frustrating and don’t dare fly IFR since i can’t trust the GPS during approaches. The avionics shop thinks it’s interference maybe from my ELT but I unhooked it to check and same result. I am wondering if the antenna itself may be the problem but because it’s intermittent it works fine until it doesn’t. Any suggestions would be greatly appreciated.
