Introducing WaveNode WN-2m to our family of products


WaveNode WN-2, WN-2d, WN-2m:

  • Includes high brightness LED bargraphs (except WN-2).

  • WN-2m monitors 2 sensors simultaneously for Peak, Average, and SWR.

  • WN-2 and WN-2d Monitor 4 sensors simultaneously for Peak, Average power and coax SWR.

  • Direct USB full speed interface on all products .  

  • Backlit LCD display for stand-alone operation- Your PC is optional.

  • Oscilloscope and Spectrum Analysis of the RF Modulation- Observe IM and "Splatter" frequency components real-time.

  • Complete system includes (1) sensor, display unit, AC power module and software on CDROM.

  • Wide range of sensors cover 100 milliwatt to 8KW, 1.6 MHz to 1.3 GHz.

  • 16-bit RISC processor, 12 bit A/D converter and rugged construction.

  • C ompact and low power.  Perfect for local, mobile, emergency communications vans, and remote repeater sites.

  • NIST traceable calibration, FCC Class B, CE certification.


WaveNode Sensors for 470 MHz to 1.3 GHz.


  0-100 watt operation and are compatible with all systems. They have low insertion loss and are built on PTFE stripline with dual differential detectors. True peak and average power with SWR are displayed on your system. These units have >23 db directivity
and will display SWR accurately at power levels > 2 watts.

SHF-1 470 MHz - 750 MHz
SHF-2 750 MHz - 950 MHz

  • All software versions support RT1/RT2.


The Rotator Controller:

Features of your RT-1/ RT-2 Rotor Control System:

1. Point and click control on a map centered at your location. Just one click sends your rotator exactly where you want it.

2. Controls 2 independent rotators, and indicates both rotators on the same map. Two auxiliary antennas at 90 degrees can
    also be indicated.

3.  No alignments are necessary, but provision is made to trim the antenna pointing.   

4. Supports Overlap, speed control, and all Yaesu features. Use your rotator box controls normally also.   Uses the Yaesu
    interface plug, no opening or modification of your Rotator Control Unit.

5.  Simple connection to your control box that will never lose communication with your WN-2 or WN-2d with your Yaesu
    control box. Perfect for remote operation where reliability is most important.

High-Power VHF/UHF Sensors:

 UHF-2KW (0-2000 Watt) 120-170 MHz.

 UHF-220 (0-2000 Watt) 200-270 MHz. 

 UHF-70cm (0-2000 Watt) 410-470 MHz.

These sensors use a unique "COAX Directional Coupler" to display Power and SWR with very low insertion loss. Insertion loss is less than 2 watts with 1.5KW forward power. 

Accuracy +/- 10%

Attention WN-1 Owners

We have not produced the WN-1 for over five years, but we get inquiries from blind Hams seeking these older units because of their voice and tone announcing.   If you have a WN-1 control box that is no longer in service and you wish to donate it to a blind Ham, please let us know at    We will bundle it together with a new sensor and cables and donate to a blind Ham via HandiHams.   Thanks and 73.
