Mini PCIe half size wifi card with 2 antenna connectors, only one connected?

I saw a mini-PC with a mini PCIe half size wifi card with 2 antenna connectors on it, but only one was actualy connected to external antenna!? Is that enough for full functionality?

It is.

Ok, thanks!
Does that stands also for cards with 3 antenna connectors (and with Bluetooth), or that is different case?

You'll get better signal with two or three antennas though.
