The Komunica SX-1000 is a high-precision SWR (Standing Wave Ratio) and power meter designed for accurate measurement of RF output power and SWR across an exceptionally wide frequency range—from 1.8 MHz to 1300 MHz. Whether you’re working with HF, VHF, or UHF bands, this compact and robust meter is a powerful tool for radio amateurs and professionals who need reliable monitoring across multiple transmission bands.
With support for multiple power ranges and connector types, the Komunica SX-1000 is ideal for aligning antennas, fine-tuning transmitters, and maintaining optimal performance in your radio system.
✅ Ultra-Wide Frequency Coverage:
Accurately measures across 1.8–160 MHz (HF/VHF) and 430–1300 MHz (UHF), making it ideal for multi-band transceivers.
✅ Multi-Range Power Measurement:
Supports four selectable power scales: 5W, 20W, 200W, and 400W on HF/VHF, and up to 200W on UHF.
✅ Low Minimum Input Power:
Detects as little as 0.5W, making it suitable for QRP (low power) operations as well as high-output transmitters.
✅ High Accuracy Readings:
Measurement accuracy ranges from ±5% to ±12.5%, depending on the selected power range.
✅ Dual Input Connectors for Band Flexibility:
TX-PL for 1.8–160 MHz
TX-N for 430–1300 MHz
✅ Backlit Display with Optional 12V Input:
Operates independently of DC power—12V input is only required for screen illumination, not for core functionality.
