If I may, I had this exact issue that I describe in detail here: Intermittent GPS issue related to "unbroken" antenna
I kept this antenna and installed it again a few times to confirm and it breaks the GPS. Maybe @Yarbo-Forum would like to study it to see what is wrong with it? No physical damage but clearly not functional. This seems to be the issue here too. Again, Yarbo, I really think that a lot of the GPS issues you have are related to the antennas that become damaged without any physical evidence to it (water? Condensation?)
