Stable high-voltage power runs up a 50 m tether from a portable ground station to a lightweight aviation-aluminum air module on the aircraft, so the drone can hold station for hours instead of minutes. A 5-inch high-brightness display, real-time fault monitoring, and an audible power-loss alarm keep the operator informed, and the backpack-friendly ground station and quick-disconnect design make it fast to deploy in the field. It is purpose-built for persistent surveillance, tactical overwatch, and other missions where the drone needs to stay up.\u003c\/p\u003e\n\n\u003cblockquote\u003e\u003cp\u003eContinuous tethered power for the DJI Matrice 4E and 4T.

The TK3-M4 is designed for the DJI Matrice 4E and Matrice 4T. The aircraft is sold separately. When tethered, the aircraft operates from ground power over the tether; effective operating height is governed by the 50 m tether length. Follow CZI and DJI documentation for installation and operation, and observe local regulations for tethered UAS operations, including any lighting, marking, or notification requirements that apply in your area.\u003c\/p\u003e\n\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eWhich aircraft does the TK3-M4 work with?\u003c\/summary\u003e\n  \u003cp\u003eThe DJI Matrice 4E and Matrice 4T.

The benefit is endurance, not altitude: the aircraft can stay aloft for long-duration missions rather than being limited by battery time.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eWhat does the ground station show me?\u003c\/summary\u003e\n  \u003cp\u003eIts 5-inch high-brightness screen displays output power, line strength, and system status, along with on-screen fault diagnostics.
