external GSM antenna for i-mate JasJar

[kcchesnut]

i'm using a JasJar on T-Mobile 1900 Mhz GSM.
my home is in a valley, and it just barely works.
the JasJar has an external GSM antenna port,
so i wanted to get a magnetic base antenna to connect to when at home.

any ideas on what antenna to get, as well as what adapter i need to connect it to the phone?

Thanks,
casey
