An ultra wideband active antenna platform can be deployed globally. A plug-and-play radio unit is removably attached to an outside of the active antenna. The PAPR can be removably plugged into a docking station to provide different technology or frequency bands specific for customers in different regions without the costly replacement of the whole antenna.

In addition, the heat-generating sources (power amplifiers) with heavy heatsink structures are separated from the main antenna body, so that the whole active antenna can be installed separately since the installation weight of the antenna would be reduced.
