Antenna for ET-301 module

I plan to use the ET-301 module with a 3.3V device.

So I need a 3.3V antenna and the SKU#: ANT-EMB-SMA seems right but the VTorch G050A specification indicates a voltage of 5V (the Spark Fun description indicates 3.3V).

Witch one is right ?

The Vtorch datasheet is generic. The batch of antennas that we stock are all 3.3V antennas.
