• Simultaneous Display: The dual-needle (cross-needle) technology allows for immediate reading of power and SWR without manual calibration.
• Wide Frequency Range: Coverage of the VHF and UHF bands (144–470 MHz) to support a variety of amateur and professional applications.
• Dual Measurement Scales: Choose between 30 W and 300 W for maximum flexibility and accuracy depending on the transmitter's power.
• Portable Design: Extremely compact dimensions and lightweight construction facilitate use in both fixed and mobile setups.

You will be impressed by the ease offered by the cross-needle technology of the Diamond SX40C. It allows you to simultaneously view the output power and standing wave ratio (SWR) on the same screen, without the need for complex adjustments or manual calibrations. This way, you have full control of your transmission at a glance, ensuring the protection of your equipment.

Whether you are involved with amateur radio frequencies or professional applications, this instrument fully covers the 144–470 MHz range. You can choose between two power scales, 30W and 300W, to accurately measure both portable transceivers and powerful base stations. You only need a minimum input power of 3W to obtain a completely reliable VSWR measurement.

You will appreciate the compact and lightweight construction of this instrument, which weighs only 255 grams. Fully manufactured in Japan, it guarantees top-quality materials and long-lasting durability. The built-in SO-239 connectors ensure a stable and reliable connection with standard 50 Ω cables, making it ideal for both the laboratory and your outdoor adventures.
