Re: Soldering external antenna to Orinoco a/b/g ComboCard

OK - with the better pic, I agree it's not a u.fl or any of that series.
I would try, first off, inserting the center conductor into the center 
hole, doubling if needed for positive contact. This assumes that there 
is a dielectric between the outer ring and the center hole, if not, you 
will have to create some sort of isolator. Then clip the shield to the 
outer with an alligator clip. Check the levels with whatever you have to 
check with.

This would be an inexpensive and nondestructive way to see if it works. 
If it does then you could apply solder to the leads to strengthen them 
for continued use.
