Description

HSWR1 – Hambuilder SWR Meter (0–125W, HF 3–30 MHz)

The HSWR1 Hambuilder SWR Meter is a compact and reliable instrument designed to monitor Standing Wave Ratio (SWR) for HF radio operations. It supports power levels from 0 to 125 watts and covers the 3–30 MHz HF band, making it suitable for a wide range of amateur radio applications.

Powered by an external 12–13.8 V DC supply, the HSWR1 provides clear visual feedback through LED indicators, allowing operators to quickly assess antenna matching and system performance.
