How can I connect antenna to GPS Module ET314AC?(it is not on a breakout board). I have an antenna like this one GPS Active Antenna and Here is the datasheet of ET314ACET314AC Datasheet.I want to connect it manually without any connectors or other things in fact I want to cutoff the connector from antenna.

  • Just solder the center wire to the ANT pin, and the outer shielding to the GND pin.

  • What about power supply? How can I connect battery to that antenna as it is an active antenna? Nov 13, 2015 at 15:56
  • Have you actually read the datasheet? It's plainly there in black and white.

Read the datasheet!


This pin is reserved an external DC power supply for active antenna. If using 2.85V active antenna, pin 19 has to be connected to pin 20. If the bias voltage of active isn’t 2.85V,you can input bias voltage of you need to this pin.

So just wire the antenna to the RF_IN pin and GND, and connect pin 19 to +3.3V (since your antenna is 3.3V not 2.85V).
