The Diamond SX-400 SWR/Power Meter is a precision in-line RF measurement instrument designed to monitor standing wave ratio (SWR) and forward/reverse RF power in real time during transmitter operation. Built for amateur radio operators and HF/VHF station use, the SX-400 provides reliable visual feedback to optimize antenna matching, minimize reflected power, and protect transceiver output stages from high SWR conditions.

Featuring a rugged mechanical meter movement with dual scales, the SX-400 makes it easy to interpret SWR and power readings simultaneously—without requiring electronic displays or external power.

Ideal for:

  • HF and VHF Station Monitoring

  • Antenna Tuning & Matching Verification

  • Transmitter Output Protection

  • Portable Field Deployments

  • Repeater and Base Station Diagnostics
