intermittent GPS failure on GNS430

Former Member over 12 years ago

Hello
Has anyone had an intermittent GPS failure on GNS430 ?

I have an intermittent loss of GPS signal? . I can fly for days without any problems then for no apparent reason the gps will go off for a while before coming back on.

I flew to London today ,the gps was inoperative for 50 minutes of the hour it took to fly there.
On the way back it was fine ? I haven’t replaced anything yet my guess is to replace the coax and antenna any suggestions appreciated :confused:

Aircraft Vans RV-7
Antenna location underneath the upper cowling ( popular choice of location on RV's )

Cheers

I experience similar issues that randomly the gps reception is lost and comes back after landing. I read in another forum that this might be due to broken gps antenna.But I have no evidence.
