GPS antennea seems to die, is this typical of inexpensive units?

[cernese]

I've been running a "blue" system since the fall of 2017! 
At the end of last month, near end-October-2022, I get a startup sequence where the GPS unit responds and then dies.
First 1 satellite and a few seconds later, a 2nd satellite, and then it stops responding completely.

It was an inexpensive "active antenna 28dB Gain, 3-5VDC, SMA connector" widget and I'm going to order a replacement unit, any suggestions or should I just pick what I find in amazon.com ?

Thanks,
Dan

Hi Dan... have you seen this thread???

I updated the firmware, a voila!  It works again!

Note to others:  I have Windows 10, I mistakenly tried the Windows 8 driver, no go (even though the virtual COM3 port shows up).  Installed Windows 7 driver, that worked.

However, the flash either reports no com ports or failed to enumerate com potrs-- so I edited the .ini file and changed it from 1 to 3 (my device manager shows it as COM3), and it worked first time!
