Outstanding Efficiency Lowers Ownership Cost

Exceptional efficiency (70%) and low maintenance overhead make the NL Series transmitters extremely cost effective.  High efficiency means less energy is wasted, reducing cooling and ventilation costs.

Powerful Building Blocks

Advances in amplifier technology and our patent-pending pulse power recovery technique make the NL Series's Class D RF amplifier extremely efficient and capable of operating at high power continuously while generating minimal waste heat.  The result is very low transistor junction temperatures assuring reliable operation even in the highest ambient temperatures. 

Robust Design & Inherent Reliability

Tens of millions of hours of real-world operational experience have gone into the design and construction of the NL Series which combines 24 hot-swappable modules in each power cabinet with front panel access.  The result is unparalleled performance and reliability - The NL Series can experience significant RF amplifier failure with no change in pulse shape or timing.  Further losses reduce amplitude while maintaining the integrity of pulse shape and timing. 

Automatic Standby Exciter

A unique feature of Nautel transmitters is the complete duplication of the critical exciter component.  Should a failure occur, the transmitter automatically switches to the built-in standby exciter.  This dramatically enhances the already high operational reliability inherent in the modular solid-state design.  

Class Leading Space Efficiency

At half the size of competing solid state high power LORAN transmitters, the NL Series still offers easy and spacious access to all major serviceable components and modules.

Redundant Architecture

Fully parallel redundant architecture on all active components ensures no single point of failure and makes service as easy as pulling and replacing a module.

Lightning Protection

As experts in the proper transmitter design and site layout necessary to protect equipment from damage due to lightning strikes, Nautel ensures that even in the harshest environments, your transmitters remain on air. 

Ease of Operation and Maintenance

The NL Series ability to stay on the air all but eliminates the need for emergency site visits.  Repairs or module replacement can be performed whenever it is convenient.  Maintenance is simplified with advanced remote control and monitoring capabilities.  The NL Series is ideally suited for unattended, automatic or remote-controlled operation.
