You have to open the unit and disconnect at least two of the internal antenna and plug in antenna adapters. Then you can run the coax from the exterior antenna to the unit and plug them in. Then you use an app to locate your closest tower and point the antenna towards that using the T-Mobile app to see your connection strength.
