Product Description

The UHF Data Link Unit (UDLU) is a Line of Sight (LOS) data communication
system for long range operations on both manned and unmanned platforms.
This system is specifically tailored for use with UAVs, Mission helicopters,
Ground stations and other fixed-wing aircrafts. It supports simultaneous
interfacing with dual IP sources and offers full-duplex operation through Time
Division Duplex (TDD) or Frequency Division Duplex (FDD) modes, makes it
versatile for various applications.
The system enables the exchange of diverse data types, including Audio,
command and control signals, telemetry and live video, between ground
stations and UAV/aircraft. Current hardware configuration operates in UHF
band with user-selectable frequency range, which can also be extended to Lband and C- band for broader compatibility.
