Can anyone point me to a source for an external clip-on type antenna
for the MMCX connector(s) on a Senao PCcard adapter?

One will do you, as long as you attach it to the correct antenna port. From http://www.netgate.com/help.html:
I have the 802.11b 2511 CD PLUS EXT2 200mW EnGenius card with the external antenna leads. Do I have to hook up both antenna leads? Which is the main lead?
On the 2511 CD PLUS EXT2 with external antenna leads there is a 'main' and 'aux' antenna lead. Hold the card with the PCMCIA connector part pointing to the right, the top of the card facing you (with the light on top), the main antenna is the one on the bottom.
You only need to attach ONE antenna to this card to have it work properly. The second antenna lead (auxiliary) is only needed if you want to support receive diversity
