Dear all,

Regarding the recent posts about the miniature connectors and cables, I
agree, they do sound like Hirose (or some clone of Hirose) there are two for
the purpose of antenna diversity and they are difficult to crimp.

I just thought I'd add my own little contribution from my experience using
very small connectors like this and very thin cable. When you start playing
about with the cables and antennas, unless you really know what you're
doing, you're likely to end up with your connectors and cables radiating as
much energy as your antennas (if not more). If this does happen you may
reduce the effective gain of the antennas rather than increasing it. You may
also reduce the isolation between the two antennas, causing the effect of
diversity to be diminished.

Don't let that stop you though :-)

The connector on the minipci cards is a surface mount u.fl connector...  
you can probably find them from a large distributor of hirose electronics
rf connectors. you won't be able to crimp something that small unless
you're a jeweler or own a robotic assembly line. these connectors will not 
survive repeated connection/disconnection cycles or significant strain so 
they're only appropriate for internal connections. or connectioning to a 
larger bulkhead jack.

a cable you'd use with that would be something like co-6f-(d)sb-cx50 from 
hitachi cable which is .81mm diameter.
