## Overview

The Upgraded NanoVNA-H4 is a compact, professional-grade vector network analyzer featuring a 4-inch touchscreen and a broad 9KHz-1.5GHz frequency range. It supports advanced antenna measurements including S parameters, SWR, phase, and delay, with built-in MicroSD storage for data logging. Designed for electronics engineers and radio enthusiasts, it offers PC connectivity for exporting measurement data and comes with essential calibration accessories, making it a must-have tool for precise antenna tuning and RF diagnostics.

## Description

Versatile vector network analyzer with 4" touchscreen, advanced measurement capabilities for antenna analysis, electronics engineering, and radio DIY projects.

Review: Good For Antenna Tuning - Nice little gadget, easy to calibrate and use, amazing how so many functions can be squeezed into something so small
Review: It works as expected, very useful tool - I was a little sceptical about this device but it has exceeded all expectations, a little tricky to navigate the menu structure (use the supplied cheat sheet and it's a breeze), otherwise it's a great tool with an easy to read display. The only critical comment I can make is about the charging cable, it's a very cheap usb-c cable and doesn't work one way round, I use a higher quality cable and have no problems with it.

## Features

- 😊【2022 UPGRADED NANOVNA ANALYZER】: SeeSii Nanovna-h4 Vector Network Analyzer is developed by Hugen. With the latest 4.4 version, a 9 KHz-1.5 GHz measure range, a 4.0-inch LCD touchscreen, mini and portable design. This Antenna Analyzer provides outstanding vector network measurement capabilities and is perfect for evaluating antenna resonance and SWR. It is a very handy & smart analyzer for electronics engineers, amateur radio operators, or radio diy amateurs
- 😊【BUILT-IN MICRO-SD PORT & TIME DISPLAY】: The latest antenna analyzer with MicroSD card port, so you can save field test data or screens to a MicroSD card at any time, supports up to 32GB memory card. (Not included in the package).In addition, different from the old version NanoVNAs, the date and time can be customized, which is convenient for you to record further and save data..The default firmware's main function is used for antenna performance measurement
- 😊【IMPROVED FREQUENCY ALGORITHM】:The Vector Network Analyzer can use the old 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.Great for trouble shooting antennas and improving performance
- 😊【PC CONNECTION & TX/RX FUNCTION】:The vna analyzer uses PC software NanoVNASaver, it can connect to a NanoVNA and extracts the data for display on a computer for saving to Touchstone files. We can export Touchstone (snp) files for various radio design and simulation software through PC software.In addition,the default firmware is mainly used for antenna performance measurement. The TX/RX method can measure the complete S11/S21 parameters (need to manually replace the transceiver port wiring)
- 🎁【Abundant Accessories】:Equipped with 1x NanoVNA-H4(with 1950mA-h battery), 1x USB Type-C cable, 2 x 15cm SMA male to male RG316 RF cable, 1x SMA male calibration kit - OPEN,1x SMA male calibration kit - SHORT ,1 x SMA male calibration kit - LOAD,1 x Touchscreen pen.It's very useful as an antenna analyzer for your ham station, easy to set without fancy calibration.The firmware of the nanovna-h4 can be updated by the user. New versions of the firmware needed pls contact us for download link

### ⭐⭐⭐⭐⭐ It works as expected, very useful tool
*by A***R on 21 July 2022*

I was a little sceptical about this device but it has exceeded all expectations, a little tricky to navigate the menu structure (use the supplied cheat sheet and it's a breeze), otherwise it's a great tool with an easy to read display.

### ⭐⭐⭐⭐⭐ VNA
*by L***N on 2 August 2024*

THis VNA seems to work well. I have mostly used it to measure home made Common Mode Chokes and to check VSWR for my vertical HV antenna. It seems to agree with my MFJ -259C.
