The direct connection is possible?.
I look in https://hydrography.ca/wp-content/uploads/2020/04/17_Oguntuase_Low-Cost-GNSS-Hardware-for-High-Accuracy-Marine-Positioning_Submission_4_CHC2020_Publication_20200316.pdf, but the use a splitter and power the antenna with a NETR9(Trimble).
Thanks.

The main parameter is voltage, I think?
Input Voltage. . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.5 V DC to 20 V DC
MSS Narrow Band Mode (1555 to 1559 MHz):

The ZED-F9P is *not* going to power this, so yes you’re going to need an active splitter or Bias-T
