|My clock has been sitting outside and behing a window for at least 6 hours. Still no gps fix, it just keeps counting up. I did see the GPSMOD1315 antenna as an option, but shipping is very expensive because i can only get the GPSMOD1315 from the US (I am based in The Netherlands)|
Is there a gps antenna which is available in europe?
(Note: i sourced all components and pcb myself)

|Mouser shipping is free if you order more than something like $40. Maybe you could combine it with some other parts you need? Or get a few antennas and re-sell them.|
But it might not be the antenna that you need. The original antenna works fine for me where I live.
It could possibly be the ATtiny needs calibrating - try sending it some fake data with a USB serial adapter. There's a python script in the github repo to do that.
It could be the GPS module is a different type, if you sourced it yourself, so also try listening to its output with a USB-serial adapter and see what it's saying.
If the GPS module has an LED on it, it will start flashing when it has a fix, so if you see that happening and it still doesn't display the time then the problem is not the antenna.
