## Description

NanoVNA-H4 Vector Network Analyzer Kit 10KHz-1.5GHz HF VHF UHF Antenna Analyzer Measuring S Parameters, Voltage Standing Wave Ratio, Phase, Delay, Smith Chart with 4" LCD Touch Screen Nano VNA

## Features

- This NanoVNA-H4 with 4inch LCD Touchscreen, Portable with 1950mAh battery rechargeabe powered or USB powered. Can last longer working time.
- The 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.
- This Antenna Analyzer is a DIY product that provides perfect vector network measurement capabilities, tiny and handheld.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)
- 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.
- The metal shield is designed to reduce the external interference and improve the measurement accuracy. Use strong and secure power supply at the same time. Enhanced performance in all aspects

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect little VNA!
*by D***Y on March 10, 2024*

Had it out and analyzing my antennas within minutes. Worked exactly as expected and am very happy with the purchase. Found out one of the handy-talkie antennas I have used for years was not nearly as good as I thought! Great little tool with a ton of features!

### ⭐⭐⭐⭐⭐ Impressed with capability
*by W***E on February 3, 2024*

I bought this to verify VSWR on Amateur Radio antennas and I have to say I am impressed. It might be a bit of a learning curve for someone not familiar with Vector Network Analyzers but there is help online. The capability of this little instrument is so impressive. It is small but the display is easy to read and it seems pretty accurate. I was tuning a 6 meter antenna and it was so much easier than doing it with a transmitter and reflected power measurements. The kit come with the calibration set needed of SMA open short load devices. The only thing extra needed is some SMA to UHF or N connectors. After seeing this impressive capability, I will be looking at the spectrum analyzers also.

### ⭐⭐⭐⭐ Nice instrument, poor documentation.
*by K***O on January 9, 2022*

I've only used this for antenna SWR measurements so far, but it seems to work well. It's nice to have the antenna reactive components separated out on the Smith Chart display - it allowed me to fine tune the capacitance "spider" to optimize the SWR on a vertical antenna. That would not have been possible with a directional wattmeter setup. I dropped a star because the documentation for this product is dismal. It appears that there is a lot of potential in this instrument that is untapped (at least by me) due to the lack of instructions. Documentation on the internet seems to be hit and miss; some of it applies to the V4 version and some doesn't. I haven't figured out how to use the TDR function yet - still working on it. Good little box overall; the capability/price ratio is amazing!
