The HTL RDM-1K represents a new generation of RF power and SWR meters that integrates both digital touchscreen technology and the traditional cross-needle display for ultimate accuracy and usability.
With frequency coverage from 1.8 MHz to 200 MHz, the RDM-1K supports both HF and VHF operation.
It handles up to 1 kW of continuous power across the full band range, making it ideal for antenna testing, transmitter tuning, and professional station calibration.
The dual-display system shows forward power, reflected power, and SWR values simultaneously—through intersecting analog needles and a digital readout.
The full-color touchscreen allows users to switch power ranges (10 W, 100 W, 500 W, 1 kW), adjust brightness, and change operating modes with a simple tap.
Every unit is designed in Japan and manufactured in Taiwan, ensuring exceptional precision, reliability, and craftsmanship.
The RDM-1K provides engineers and radio enthusiasts with professional-grade measurement accuracy in a compact, intuitive form factor.
