Re: Female MC connector?

That is interesting. I have an orinoco A/B card but have never popped the 
antenna cover to look at the connections. You might take a look at. 
http://www.fab-corp.com/  They sell several types of connectors that would 
be suitable. Also if I remember correctly a crimp tool. And of course you 
will want to keep the existing mc pigtail intact for its current use. So it 
looks like buying a new pigtail and a matching connector for the card would 
be in order.
