“Is the NanoVNA suitable to measure/adjust a typical antenna duplexer? This video compares the NanoVNA-H4 and the SAA-2N VNAs with a professional VNA (Tektronix TTR506A). Will the limited dynamic range of the NanoVNA get in the way of making a good measurement, or limit the ability to adjust the duplexer? Watch and find out…” Read more

This video briefly shows how to setup and use the NanoVNA to sweep an antenna system (antenna, transmission line, transmatch, etc.) to measure its VSWR, Reflection Coefficient, etc., and then shows how you can use it to monitor the tuning behavior as you make adjustments. The basic steps include: – Setting the traces that you […] Read more

“The NanoVNA does many things. Two of which are testing coax cables for loss and length. Jim W6LG shows how to do both in this first video about the NanoVNA. In a subsequent video, Jim will show how the NanoVNA can be used to check antennas for resonance, impedance and reactance. The software that Jim […] Read more
