Buy another device, poooor sensitivity, never manage to provide position.
Really poor sensitivity. While a similar 6M device with identical looking antenna locks in a few seconds and tracks at least 10 satellites indoors. This device do not even detect a single satellite. I managed to get it to track 2-3 satellites by taping it to a window, but even after several hours did it not manage to produce any position. So buy other devices at same pricelevel, these are only good at delivering time, and only when outdoors or in a window.... ( I bought two devices, and they both show the same behaviour.).
The similar device I compare with is the GY-NEO6MV2 Flight Controller NEO-6M GPS Module For Arduino EEPROM APM 2.5
( 192163653482 ) which I bought in 2017. 6M based instead, and the antenna is connected using a couple of cm of cable instead of being mounted directly on the board.
