I'm currently trying to set up a BN-880 GPS module with RPI4. The module seemed to work fine at the beggining but after couple of days of testing and playing with I saw that it loses a fix quite often making it impossible to work with. I tried to take it outside, power it up with external power source but with no success. I was thinking if something could interfere with its signal but I also tried to isolate it from anything possible also without success. My question is if I soldered a different antenna than the one that it came with would it help? What antenna should I use and what parameters I should focus on in antenna choice?
Thank you for any help.
