CTech designs, manufactures and provides novel and complete end-to-end communication solutions for unmanned Aerial Vehicles (UAVs). UFUK-DLX45 is intended for line-of-sight (LOS) Data communication applications, and consists of All the components to establish a secure and robust data link for the most severe environments and conditions.

It is a complete Full Duplex(FD) communication System solution containing the paired datamodems, RF blocks, and antennas for both ground and airborne terminals. The up-link carries the command and control information for the real time operation of the UAV, while the down-link conveys all the onboard sensor data, video and audio payload to the ground station.The video encoder on the airborne modem processes the payload information, enabling simultaneous HD and SD video transmissions.
