The Zetagi 203 SWR/Watt meter is a highly functional instrument for measuring SWR (standing wave ratio) and wattage in radio communication applications. Its compact design and intuitive interface make it accessible to amateur radio enthusiasts and seasoned professionals. With dimensions of 140 mm in width, 80 mm in height, and 60 mm in depth, and a weight of 500 grams, it is portable enough for field use while still providing robust performance.

One of the standout features of the Zetagi 203 is its precise SWR measurement capability, which operates across a frequency range of 3-200 MHz. Monitoring SWR is crucial for ensuring that antennas are efficiently tuned, as high SWR values can lead to significant signal loss. The device helps users optimize their antenna setup, enhancing overall communication effectiveness. Additionally, it includes clear instructions for SWR measurement, making it user-friendly for individuals at all skill levels.

Beyond SWR, the Zetagi 203 also provides accurate wattage readings, essential for assessing the output power of radio transmitters. It supports power measurements in three scales: 10W, 100W, and 1KW, with a maximum power capacity of 1KW and an accuracy of ±5%. The device connects via a PL259 patch lead and has a minimal insertion loss of 0.05 dB, ensuring it does not significantly impact signal quality. This combination of features makes the Zetagi 203 an indispensable tool for anyone serious about radio communications.
