Call 0345 2300 599The WaveNode WN-2.UHF is a VHF/UHF RF sensor for use with compatible WaveNode monitoring systems and the Sierra Radio Systems SIR-335 Two Port RF Watt Meter Control Module.
Covering 120-470MHz with a maximum power rating of 300W, this sensor is ideal for VHF and UHF stations where forward power, reflected power, and SWR monitoring are required. It is the sensible sensor choice for 2m, 70cm, and other compatible VHF/UHF installations using the Sierra SIR-335 watt meter control module.
The WN-2.UHF is fitted with 2 x N female connectors, making it well suited to VHF and UHF installations where N type connectors are preferred for lower loss and better higher-frequency performance.
Key Features
- VHF/UHF RF power sensor
- Suitable for use with the Sierra Radio Systems SIR-335 watt meter control module
- Covers 120-470MHz
- Maximum power rating of 300W
- 50 ohm impedance
- 2 x N female connectors
- Suitable for 2m, 70cm, and other compatible VHF/UHF station monitoring
- Allows forward power, reflected power, and SWR monitoring when used with compatible control hardware
- Good choice for VHF/UHF fixed-station, repeater, and remote monitoring installations
- Passive RF sensor with no separate power supply required
Typical Uses
- VHF/UHF station power monitoring
- 2m and 70cm power monitoring
- Remote station RF monitoring
- Repeater site RF power monitoring
- Use with the Sierra SIR-335 watt meter control module
- Monitoring transmitter output power
- Monitoring antenna system performance
- Forward and reflected power measurement
- SWR monitoring in station automation systems
System Notes
The WN-2.UHF is an RF sensor and must be connected to compatible monitoring hardware to display or process power readings.
When used with the SIR-335 Two Port RF Watt Meter Control Module, the sensor provides the RF measurement point while the SIR-335 integrates the readings into the Sierra Station Controller system.
For HF high-power installations, consider the WN-2.HF sensor instead. For low-power HF or QRP installations, consider the WN-2.QRP sensor.
