The integrated, highly-regulated 3.3v bias-tee is ready to power your RF accessories--no hardware or software modifications are required to activate the bias-tee. The bias-tee is protected by an automatically resetting fuse, to ensure your investment is safe from accidental short-circuits of the RF input.

Compared to R820T-based devices, this E4000-based SDR excels at sensitivity at <500MHz and >1500MHz, and is capable of far higher frequencies--up to approximately 2350MHz. There is a small gap in frequency capability near 1100MHz. As such, we do NOT recommend this device for ADS-B usage. For ADS-B applications, consider the NESDR SMArt instead, NooElec SKU 100700.
