GPS Active Antenna


How do I enable the bias voltage for an active GPS antenna on the mangOH Red?


If you look at the schematic it looks like L300 which is a 47uH inductor connects the GPS U.FL connector to VCC_3V3. I believe it comes out the box configured for an active antenna.


Thanks. That is what I was thinking as well. Yesterday, the GPS didn’t want to find my location and I was swapping antennas. This morning I turned on my mangOH Red with the active antenna connected and everything is working. I guess it didn’t like me swapping antennas.



I’ve seem similar issues when swapping cellular antennas.
