Intel 4965 AGN wireless card connecting aerial

[marmalade]

I have just bought an Intel 4965 AGN mini express card for a laptop. It has 3 connections labeled:
1 on the left side of the card
3 in the middle and of the card
2 on the right side of the card
To which do I connect the single aerial cable that is at present used on my present (Atheros)card
Thanks
