AirCard 763S external antennas

Hello,

I recently acquired an AirCard 763S. Our location is remote and signal is not super strong. If I want to install external antennas, do I need to install two for the two terminals or only one will do?

Can any SMA Yagi 3G antenna do the job, is there any recommendation as to what I can install to maximize the signal?

Does all the above applies to the AirCard hub in case I buy one?

Cheers,
Laurence.
