It looks like this antenna requires 3.3V bias on the center pin to power the LNA inside? What voltage is supported on the X410's center pin? Often these things provide a bias to the active antenna to power it.
If the X410 does not provide a bias voltage (or the wrong one - e.g. 5V), you may try putting a Bias-T between the antenna and the USRP and feeding 3.3V to the antenna that way. Do you have another GPS device that you can use with the antenna to eliminate the possibility that the antenna is bad? On Wed, Mar 9, 2022 at 9:45 AM Marcus D.
