Chelegance JLOAD-200SO 200W RF Dummy Load, DC–520MHz, 50Ω, SO-239

The Chelegance JLOAD-200SO is a high-power RF dummy load built for amateur radio operators who need a reliable, no-compromise solution for testing, tuning, and safely terminating transmitters up to 200W continuous. Covering DC to 520 MHz, it handles HF, VHF, and UHF bands in a single unit.

The passive air-cooled design uses a nickel-plated copper shell and silver-plated copper inner conductor for excellent heat dissipation and low loss — keeping VSWR at ≤1.2 across the full frequency range, even during extended operation.

Key Features

• 200W continuous power rating — suitable for high-power HF, VHF, and UHF transmitters
