The context mentions an external antenna for the T-Mobile TMO-G4AR, which comes with a built-in cable and an SMA connector for possible extensions. It also discusses testing the antenna’s performance compared to the stock unit and another external antenna. However, it does not specify where to purchase the antenna.
