I'm having a lot of trouble with my second Ublox. Very similar to the first one i had.
I've hooked up everything correctly...the module worked flawlessy for 1 week, and then mysteriously stopped, just like the first one.
So..the issue is, that the Ublox module (with adapter) does not pick barely ever picks up satellites now. Sporadiacally it picks up at the most 2 satellites with a decent c/no ratio.
To verify if its the location or a reciever..i checked with a parallax GPS reciever and it locked on in less than 2 mins.
The antenna on the Ublox looks ok on inspection. It was working fine and locked on beautifully for the first 3-4 times, when it was new. Now its worse than a 35$ gps reciever.
Ublox has frustrated me so much that i;m amlost going to flush this flimsy thing down the toilet.

as I went through it I learned a great deal about GPS, they created first class documentation and keep it up to date. The GPS user manual will help with advanced configuration...
I should do a DIY Drones uBlox video as it has a little bit of a learning curve.
Have you checked the voltage of the battery/ESC that you are using to power the Ardupilot. I believe that if the battery voltage gets to far below +5 vdc that the GPS will have trouble getting a lock. This has happened to several other members too.

no flushing , patience , some one will come along and get you the help you need. Meanwhile I believe the Ublox config tool will help to diagnose, did you use it? what r you using? Was there a crash involved in the equation prior to the no Sat lock issue?
