SNR Blank in NEMA sentences

I’m using a Electron 2G kit. I have tried using the on board antenna as well as 7 other external antennas to get a gps signal using the asset tracker. I have a clear view of a blue sky but all seems to never get a connection. My testing has been all cold start and these are the antennas i’ve used.

I’ve tried the normal assettracker library and the RK version. Currently I have i dumping the NEMA sentences via serial.

$GLGSV,3,1,10,70,00,002,71,15,046,72,12,094,77,52,194,*63

$GLGSV,3,2,10,78,57,302,79,11,333,81,11,249,86,08,053,*62

$GLGSV,3,3,10,87,58,017,88,53,276,*65

The SNR field is null and I don’t know why?
