Product catalog summary

Introduction
Nautel's technical document outlines the specifications and functionalities of the NRB4 Beacon Monitor Receiver and NLA/2 Active Loop Antenna, as well as the Vector Series NDB transmitters and associated components.

NRB4 Beacon Monitor Receiver and NLA/2 Active Loop Antenna
The NRB4 is a precision receiver designed for monitoring NDB signals, compliant with FAA and ICAO standards. It features a stable DDS carrier frequency reference, IF crystal filter, and various alarm indications. The NLA/2 antenna is easily tunable and can be mounted on different surfaces.

Vector Series NDB Transmitters
The VR125 and VR250 transmitters are reliable, solid-state NDB transmitters with power outputs of 125 and 250 watts, respectively. They feature a sophisticated GUI, remote control capabilities, and compliance with ICAO Annex 10 standards. They offer high efficiency and optional DC backup.

Automatic Tuning Unit (ATU-LP)
The ATU-LP matches antenna impedance to the transmitter's output, ensuring constant field strength and system availability. It includes automatic tuning and resistive matching, with remote control options to minimize RF exposure.

VR-Link2 Remote Control and Monitoring
The VR-Link2 unit provides web-based control and monitoring of NDB transmitters and ATUs. It supports multiple connectivity options and can interface with up to four ECMP3 panels for extensive remote management.

CL-40 NDB Antenna
The CL-40 is a compact, self-supporting antenna with capacitive top loading for efficiency. It is designed for sites with height or space restrictions and offers easy installation and maintenance.

Additional Antenna Solutions
Nautel also provides other antenna configurations, including symmetrical 'T' style and base-insulated lattice towers.
