I have a GNS430W and an older Garmin GPS unit and it's becoming more frequent and for longer periods when i lose the GPS signal. I have a back up hand held unit and that confirms that GPS source (as well as skydemon) is still active. I'm now convinced it's the antenna or something associated, as both fitted GPS drop out together, for no apparent reason. They rarely come back on during flight and require on/off to 'reboot' despite the fact they are both continually scanning and gathering location data etc.
Is this likely to be a loose connection/bad wire or can the antenna give up the ghost and if the latter how can this be proven, especially if its intermittent failures? I think i'm about to enter into a process of elimination with this, but any steer would be appreciated. PA28 Archer II. I'm curious to know if there are known antenna/receiver issues, or shall i just go looking. (or await the annual)
thanks
