NRB4 Beacon Monitor Receiver and NLA/2 Active Loop Antenna
Nautel’s NRB4 Beacon Monitor Receiver is a precision
receiver for the off-air monitoring of the transmitted
NDB signal. It is compliant with applicable FAA
and ICAO requirements for the monitoring of low
frequency NDBs.
Nautel’s NLA/2 Active Ferrite Loop Antenna is used
in conjunction with the NRB4. A versatile mounting
bracket makes it easy to install on flat surfaces or on a
2.5 inch diameter, vertical pipe. Tuning is accomplished
with easily adjustable links.

The ECMP3 is an extended control and
monitoring panel intended to provide basic
control and monitoring for a single VR125
NDB system.
The Nautel Vector Series VR125 is a field proven, highly reliable,
state of the art, solid-state non-directional radio beacon (NDB)
transmitter. Highlights include:
The ECMP3 may be interfaced directly
to the VR125 NDB transmitter via the
optional Site Interface board. Up to three
external ECMP3s and one internal ECMP3
may be connected to the optional VR-Link
remote control and monitoring unit via
RS-485 serial communication. Highlights
include:
•Sophisticated graphic user interface (GUI) for easy maintenance
and troubleshooting.
•Simple remote control/monitoring of
Vector NDB system.
•7 LED indicators.
•Vector transmitter timer enable control.
•Audible alarm, with acknowledge.
•Test feature.
•Brightness and volume control.
•Spare user configurable control/
monitoring.
•RS-485 interface to optional VR-Link
remote control and monitoring unit.
•125 watts, field adjustable continuous carrier power.
•Available in single or dual (main/standby with automatic
changeover) configurations.
•Synthesized exciter uses advanced DDS technology to produce
highly stable RF drive at the desired operating frequency.
•Extensive automatic fault monitoring, with 256 event log, for faster
troubleshooting.
•Extensive remote command/control and monitoring for fewer site
visits.
•Remote control and monitoring of the ATU to limit worker exposure
to strong RF fields, in keeping with Safety Code 6 / IEEE C95.11999.
•Compliant with the specifications and recommendations of ICAO
Annex 10, Vol. 1, Part 1, Section 3.4.
•CE certified.
•High overall efficiency (70% or better) results in low power
consumption and reduced operating costs.

The ATU500SR is an automatic antenna
tuning unit designed to match the
impedance of the CL-HD antenna to the 50
ohm output impedance of the VR125 NDB
transmitter.
•Automatic antenna capacitance tuning
using dual astatically wound loading coils.
•Standard adjustable series resistor
optimizes the tradeoff 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.
•Powered by 24 Vdc, supplied from VR125.

Nautel’s CL-HD Helideck Antenna is a self-supporting “long wire”
antenna which is intended for use around the world on offshore
oil and gas platforms*. The CL-HD Helideck Antenna is intended
primarily for use with low and medium powered aeronautical
non-directional radio beacons (NDBs) operating in the LF and MF
bands. The CL-HD is designed for installation around the perimeter
of the helicopter landing pad below the deck level, for operation
in the frequency band of 190-1800 kHz, and compliance to
CAP437. Highlights include:
•Omni-directional.
•Ease of maintenance.
•Designed for harsh offshore environment.
•Whip Antenna Alternative.
