NanoVNA-H4 Option
Features:
This Nano VNA is a DIY product that provides perfect vector network measurement capabilities, tiny and handheld, stand-alone with 4-inch LCD display, portable with 1950mAh battery powered or USB powered.
The improved frequency algorithm 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.
The default firmware main function is used for antenna performance measurement. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, 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.

Product works as described and matches the functionality i was expecting. The interface is clear, accessories helpful, and was easy enough to use that even a layman like me was able to analyze some antennas i had laying around to verify the claimed frequency ranges.

The nanovna arrived quickly, and in good shape, have only tried it a little but seems to works good. I did a swr test on an antenna and it was perfect.

Check an antenna, check a cable.
.comes with all the accessories to test and calibrate the vna.
Most people will use it every now and again and only i use one or two features but watch a few good lengthy videos to figure out what all the capabilities really are.

The description was accurate. The item arrived safely. I haven’t tried all it’s functions as i do not know what half of it is. I got it for swr readings. Online videos showed how to set that up and turn off a lot of the other stuff . It works great for it.
