Nautel Vector Series ATU 500SR
The Nautel Vector Series ATU 500SR is an automatic antenna tuning unit designed to match the impedance of the Nautel’s CL-HD Helideck Antenna to the 50 ohm output impedance of the Nautel Vector Series VR125 transmitter.
- Automatic antenna capacitance tuning using dual astatically wound loading coils
- Standard adjustable series resistor optimizes the trade off between antenna efficiency and bandwidth
- Remote control and monitoring of the ATU to limit worker exposure to strong RF fields, in keeping with Safety Code 6 / IEEE C95.1-1999
- Compliant with the specifications and recommendations of ICAO Annex 10, Vol. 1, Part 1, Section 3.4
- Cabinet enclosure designed to meet IP66 standard
