Adding an antenna/repeater to a PCIMCI Card (notebook)

I have a home office that is out in the boonies. Is there a way that I can add an antenna or repeater to boost the signal for my wireless dialup card the company provided? I am not talking about boosting my home network, I am wanting to boost the signal the card uses to dialup the remote service. I guess I am asking if there is a cell antennae/booster for home use?
