Running an analysis for HF is just repeating the steps for a different band segment. SWR, Smith Chart plots, etc. NanoVNA vector signal analyzer can be used also as an RF signal generator. A VNA is a measurement instrument that measures the response of a network of electronics either through its reflection measurements (e.g. However, the best tool to make the impedance measurements needed to effectively design a matching network is a vector network analyzer (VNA). ![]() The video demonstrates how to calibrate and use the Nano VNA to measure SWR of a VHF antenna. Before discussing the NanoVNA and why a ham might want one, what a VNA or a vector network analyzer is needs to be discussed. A spectrum analyzer with tracking generator can check an antenna match by looking at the voltage standing wave ratio (VSWR). For more information about the capabilities of the Nano VNA, a nanovna manual can be found here. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts. While the Nano VNA can do a multitude of functions far beyond the needs of the average ham radio operator, the video I grabbed from YouTube explains the Nano VNA usage its most simplest form. I ordered my Nano VNA via Amazon to avoid running into knockoffs. ![]() Although I have not looked into it yet, software is available at GitHub to compliment or extend the Nano VNA capabilities. Buy Nanovna 10KHz-1.5Ghz Vector Network Analyzer Kit, SEESII MF HF VHF UHF Antenna Analyzer Measuring S Parameters, Voltage Standing Wave Ratio, Phase, Delay, Smith Chart with 2.8' Touch Screen: Spectrum Analyzers - FREE DELIVERY. The Nano VNA comes with charging cable and and calibration terminators. For in-depth technical details visit the Nano VNA site. Although it’s rather obvious, I feel that I should add that the Nano VNA is a delicate instrument and IMHO would not fair well in a outdoor environment such as field day.Īs it turns out, the Nano VNA is pretty much what I have been looking for. NANOVNA VECTOR NETZWERK Analyzer Board Kit für NanoVNA Analysis Board Demo BS6M7 - EUR 7,89. I just want something fairly simple that will check impedance and SWR on these weird antenna systems I build and experiment with. Although the Nano VNA covers 10 KHz to 1.5 GHz, I have little interest in anything above 6 meters. The goal was to find a fairly inexpensive network analyzer that covers 80 through 6 meters. I really like the portability of the Rig Expert Stick 230 but the price is out of scope. Most analyzers are just way too expensive. ![]() I’ve been looking around at reasonably priced network analyzers.
