HF VHF UHF Antenna Analyzer Measuring
This Antenna Analyzer is a DIY product that provides perfect vector network measurement capabilities, tiny and handheld,light and convenient, easy to use and carry,long service life.The default firmware main function is used for antenna performance measurement. The TX/RX method can measure the complete S11 and S21 parameters (you need to manually replace the transceiver port wiring).
- Measuring S-Parameter, Voltage Standing Wave Ratio, Phase, delay, Smith Chart
4inch LCD Touch Screen
Nanovna-H Vector Network Analyzer with Large 4inch LCD touch screen;
Nanovna-h4 10khz to 1.5ghz Vector Network Analyzer can use the odd harmonic extension of si5351 to support the measurement frequency up to 1.5GHz. The 50K-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic, The extended 300M-900MHz band provides better than 60dB of dynamics, and the 900M-1.5GHz band is better than 40dB of dynamics.
Type-C Rechargeable & Support PC Software Control
Built-in 1950mAh lithium battery, standby time up to 7 hours,also could be USB powered which can last longer working time.
Support Windows and LINUX Computer Control.
Using PC software NanoVNASaver, it can connect to a NanoVNA and extracts the data for display on a computer, and for saving to Touchstone files. We can export Touchstone (snp) files for various radio design and simulation software through PC software.
MF/HF/VHF/UHF Applicable

Touch screen sucks, however it works great for making and testing antennas. The stylus is like a hard guitar pick, and is far easier than using your finger. There are also buttons on top that you can use to navigate the menus.

This thing is awesome, especially for the price. I'm using as a ham antenna analyzer, and it works great for all the bands!

Nicely done and easy to use. Little hard to understand sometimes, but the numerous videos on Youtube make it an enjoyable experience. I've been a Ham and building my own antenna, mostly wire, for 49 years. I have and use a RigExpert, which I enjoy, especially while climbing towers and trees. But the understanding I have gotten from the nanoVna has made the theory so much more easy to understand. Well done.

This is one of those gadgets you didn't know that you needed until you got one. Seriously though, the NanoVNA H4 is an antenna analyzer (and much more) for anyone dealing with hobby-level radio communications. I have not used this type of analyzer before, but after watching YouTube channels, particularly Alan Wolke's (W2AEW), I knew I wanted to get one. I have an antenna analyzer that I bought several years ago from a major amateur radio equipment manufacturer, and it works well for finding SWR and other measurements related to antennas for amateur radio, particularly HF. The unit costs around $250 ($350 if you want UHF). It's bulky and runs on 8 batteries. Now comes the Nano VNA for well under $100, it is rechargeable, fits in your shirt pocket, and has applications way beyond checking antenna and radio impedance matching, although it serves that purpose extremely well. I just received the unit and am exploring its functions, so I can't say more yet, but it is well worth the money if you just want to check the impedance match between your radio and your antenna!
