When it is in the TUNE position, the standing wave indicator circuit is accessed. When the transmitter is transmitting, the brighter the LED, the higher the standing wave. Two capacitor controls are used to adjust the matching. The rear switch sets the antenna impedance.Note: Standing wave indicator LED.Note: It is essential to check the standing wave before transmitting, otherwise the ORP transmitter without high standing wave protection may burn out.Note: If quick tuning is not possible, use a network analyser for debugging. At this stage the mode switch should be set to WORK.Note: This tuner is for ORP only. Excessive power can cause components to burn out.

• Compatible with a wide range of coaxial fed, long wire and balanced line antennas, such as high impedance, low loss UHF twin-lead or 40m-10m ladder line.
• Rated at 5 watts continuous, 10 watts intermittent and supplied with BNC connectors for input/output.
• Metal housing, fine workmanship, small and exquisite, which is a great help for tough outdoor use.
• A well designed Z-match tuner has a high Q and is more efficient (less lossy) than other types of tuners.
• Note: This tuner is only suitable for ORP. Too much power can burn out components.
