The Diamond SX-20C Cross Needle SWR/Power Meter is a precision analog RF measurement tool that provides simultaneous indication of forward and reflected RF power and SWR in HF and VHF amateur radio systems. Featuring a dual-needle cross-needle movement, the SX-20C offers intuitive real-time display of forward power and reflected power on intersecting scales—allowing rapid judgement of antenna match quality and transmitter loading without complex digital displays.

Designed for use between a transceiver and antenna system, this meter helps operators optimize antenna tuning, detect mismatch conditions, and protect transmitter output stages from high SWR. Its robust mechanical construction ensures reliable performance in both fixed base stations and portable field setups.

Ideal for:

  • HF & VHF SWR monitoring

  • Antenna tuning and matching

  • Transmitter protection against reflected power

  • Field and portable operation

  • Entry to intermediate level RF diagnostics

✔ SX-20C Cross Needle SWR/Power Meter Unit
✔ User Manual / Documentation

Notes:

• Coaxial feedline and connectors are not included; this meter is installed in-line between the radio and antenna.

• No external power supply or batteries are required for operation.
