VERDANT AT 40 is a fast switching, ECCM compatible, solid state pin diode switched equipment that matches the impedance of the antenna to the 50-Ohm output of the transmitter. The ATU is mounted near the HF antenna to maximize transmission efficiency. It is suitable for subsonic aircrafts and helicopters.
