Will a wireless pci card still work if 2 antennas are connected to one antenna port?

I have a dell optiplex gx280 that I got for free, and am planning on modding it. Since it uses half height pci card covers, I cannot use my wireless card (which works in it, but the metal cover is full height). I would like to wire the antenna port traces to a spare wireless antenna port I have.

I am wondering if there wil be any change in wireless reception if two antennas are wired to one antenna port on a desktop pci wireless card. (if it even works). Thank you in advance for any help you might give.

Instability from slight differences in the antennae?

(really, I'm not sure, but I don't think it's such a hot idea)
