Compaq laptop wireless w200 antenna jack howto use

i've got a compaq laptop n800c and bought a proprietary wireless card
that fits on the back of the display. in the stock config it works
satisfactory. but want more..

during install i noticed what looked to be an antenna jack. after doing
a little research on the web i found that it was an mc card connector,
so i bought a cheap antenna, with the appropiate connector and was
looking forward to increased range. but i was disappointed to find no
increase in performance when attached.

after more time researching, all i could find was a short conversation
on some forum, where a person said that you had to do some soldering on
the pcb. and that was where they left it.

i would be very grateful for any input on the subject at all, anything
as to where to look or if anybody has had experience with this card.

Why would you assume that a cheap antenna would be better than the
inbuilt one?
What was the difference in gain between them?

Most likely that MC connector fits only LRM-100 coax which has a loss
of .4 dB per foot. Ten foot of coax plus a bit of connector loss and
a 4 dBi gain antenna has no effective results.

His W200 seems to be a re-badged Agere WA1000 which fits on the back of
his laptop. I assumed he had a short length of coax to his antenna.
