The reviewer found the updated HW3.6 firmware and improved frequency algorithm deliver a surprising measuring range to 1.5GHz, while the included EVA case and accessories make it ready for field use. It is an affordable, functional instrument that trades a larger display and advanced calibration kit for portability and value.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring range:\u003c\/strong\u003e Covers 10KHz to 1.5GHz so users can test HF through lower UHF antennas without multiple instruments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpdated firmware HW3.6:\u003c\/strong\u003e The improved frequency algorithm and odd harmonic extension of the si5351 expand usable frequencies and improve measurement reach.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2.8in touchscreen:\u003c\/strong\u003e A compact color LCD with touch control provides on-device operation for quick checks and adjustments in the field.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePC and Android support:\u003c\/strong\u003e Works with NanoVNASaver and a USB-C to USB-C link to stream data to a computer or Android phone and export Touchstone files for simulation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccessories and calibration kit:\u003c\/strong\u003e Ships with SMA short\/open\/load, cables, connectors and an EVA case so users can calibrate and protect the unit immediately.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable carrying case:\u003c\/strong\u003e The custom EVA case is waterproof, shockproof and organized with mesh pockets to keep the analyzer and cables secure on the go.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis device suits hobbyists and field technicians who need a lightweight, portable VNA for evaluating antenna resonance, SWR, and basic S-parameter checks.
