The Jetfon JX-20 is a professional-grade, highly compact SWR (Standing Wave Ratio) and RF power meter designed for precise antenna tuning and transmitter performance analysis. Operating across a wide frequency spectrum from 1.5 to 150 MHz, this dual-function instrument is the ideal diagnostic tool for testing and calibrating Citizen Band (CB 27 MHz), marine VHF, and amateur radio (2-meter band) communication systems.
Equipped with an intuitive analog interface, the JX-20 features a mechanical toggle switch supporting two selectable power measurement scales (0–10 W and 0–100 W), allowing technicians to accurately monitor forward power and standing waves up to 100 Watts. Its rugged, pocket-sized metal chassis provides excellent RF shielding and maximum portability for field operations, workshop maintenance, and mobile vehicle installations.
