1.6-60 MHz single-sensor HF meter Power ranges 30 / 300 / 3000 W Cross-needle simultaneous forward, reflected and SWR PEP monitor function Insertion loss less than 0.1 dB Compact ~640 g cabinet

Strengths

High 3 kW range suits legal-limit HF amplifiers; very low insertion loss; compact; trusted Diamond build.

Weaknesses

HF-only (to 60 MHz); lamp needs DC; +/-10% is typical-grade, not lab accuracy.

Verdict

A compact HF cross-needle meter that comfortably handles legal-limit amplifiers thanks to its 3 kW range - a solid single-band-set shack meter.

The Diamond SX-100 is a compact HF cross-needle SWR/power meter covering 1.6-60 MHz with 30/300/3000 W ranges, a PEP monitor and under 0.1 dB insertion loss. Its 3 kW range makes it comfortable in front of a legal-limit HF amplifier.

For dual-sensor HF-through-UHF coverage compare the Diamond SX-1100, or the HF/2m Daiwa CN-501H.
