Okay... using an old wooden ruler:
The Socket card is:
Total of 2 1/8 " long
The antenna appears to be 1/2 ", however, it looks like the start of the antenna is closer to the Ax than the Ambicom (but probably just looks and not in reality)
The Ambicom card is:
Total of 2 5/16 " long
The antenna appears to be 3/4". The dfference between the Ambicom and the Socket is noticable. The Ambicom antenna height looks close to the LinkSys
Some things to point out:
My LinkSys card worked great until I started having reconnect problems. I also noticed much battery usage. I returned the card.
The Ambicom never gives me any reconnect problems. The power usage is less than the LinkSys but greater than the Socket.
The Socket never gives me any problems at reconnect. The battery usage is really low. Indeed, I never take it out of the Ax.
The range on all three appeared to be the same to me.
Hope this helps. If you want, I can snap a pic of both cards in the Ax and email them to you.
If I had to pick one card, I would pick the Socket.

BTW: The dimensions of the card should be on their website at
