Did this mod back when I first got my x51, figured I could share it with you guys.
I have since seen a few people also do this mod, but with a single antenna.
I installed 2 SMA antenna cables. They go from the wifi card to the back panel. This allows me to hook up external antenna.
I went from picking up maybe 5 networks to being able to pick up 25+ networks.... houses in my neighborhood are pretty spread out too, so If I had to guess, I would say my range is well over 1500 feet now.
I am using a pair of Amped Wireless antenna (thats the brand). They are 1 watt powered antenna with a 12dbi gain.
Amped Wireless SB1000 High Power Signal Booster
Along with a killer 1102 card that I had laying around.
