⚡ Bias Tee: The 5V bias tee is disabled by default and must be enabled in software (SDR#, GQRX, SDR++, rtl_biast). The LED on the side indicates when bias tee power is active. Use with compatible LNAs and active antennas only — do not enable when connected to passive antennas without a DC block.
The Mini RTL-SDR Dongle combines proven RTL2832U + R860 performance with a precision TCXO, software-controlled 5V bias tee, and HF direct sampling — all inside a CNC aluminum shell that fits in your shirt pocket. The USB-C interface makes it universally compatible with any modern device. Whether you're a beginner tuning into FM radio or an advanced user decoding satellite signals, this dongle is the definitive compact SDR tool.
