Features of the NanoVNA-H4 for Antenna Testing:

This NanoVNA-H4 for RF Testing is a DIY product that provides perfect vector network measurement capabilities. It is tiny, handheld, and stand-alone with a 4-inch LCD display. It is powered by a portable 1950mAh battery or USB. The improved frequency algorithm utilizes the odd harmonic extension of si5351 to support measurement frequencies up to 1.5GHz. The 50K-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic range, while the extended 300M-900MHz band provides better than 60dB, and the 900M-1.5GHz band offers better than 40dB dynamics.

The default firmware main function is used for antenna performance measurement. The TX/RX method can measure the complete S11 and S21 parameters. For S12 and S22, manual port wiring adjustments are necessary. Using PC software NanoVNASaver, it can connect to a NanoVNA and extract data for display on a computer, saving it to Touchstone files for various radio design and simulation software. The metal shield is designed to reduce external interference and improve measurement accuracy.
