HI and thanks for your interest. The patch antenna was removed from the board and I'm not sure what you mean about a power wire. All four wires from the U3S are connected to the GPS board. As for a current spike this happens with or without the external antenna connected to the SMA on the QLG1.

Thanks again for your input

You will need to solder a wire from the lower end of L3, to the SMA centre connector.This arrangement suppliespower to the external antenna, from the RF Vcc supply output of the RF module. Note that it does not have short-circuit protection
