Mini RTL-SDR Dongle

The Mini RTL-SDR Dongle is a compact, pocket-sized software-defined radio receiver housed in a premium CNC-machined aluminum alloy enclosure. Measuring just 54 × 26 × 10 mm, it packs the full RTL-SDR feature set — wide frequency coverage, TCXO precision, 5V bias tee, and HF direct sampling — into a USB-C form factor built for portability and durability. Whether you're scanning radio frequencies, decoding aircraft transponders, analyzing spectrum, or receiving GPS signals, this dongle delivers professional-grade SDR performance in your pocket. FREQUENCY COVERAGE 100 KHz HF · VHF · UHF · L-band 1.74 GHz Key Features RTL2832U + R860 Tuner 100 KHz – 1.74 GHz RTL2832U demodulator chipset R860 wideband tuner Covers HF, VHF, UHF and L-band Ideal for ADS-B, NOAA, FM, ATC, and more 100 KHz – 1.74 GHz TCXO Oscillator Near-zero temperature drift Temperature-compensated crystal oscillator 1 PPM max. initial offset, 0.5–1 PPM temperature drift Accurate tuning across operating temperatures Significantly reduces frequency drift vs standard XO Essential for stable decoding and narrow-band reception Precision · Stable · Low drift 5V Bias Tee Power LNAs via coax 5V bias tee injected through the coax cable Powers LNA4ALL, HABAMP, ADS-B LNA and more Powers active antennas without a separate supply Software-controllable on/off LED status indicator on the side 5V · Software control · LED status HF Direct Sampling 100 KHz – 28.8 MHz Receive HF bands without an upconverter Covers 100 kHz – 28.8 MHz in direct sampling mode SW, MW, LW, amateur HF bands and more Enable via software (e.g. SDR#, GQRX, SDR++) 100 kHz – 28.8 MHz · No upconverter Aluminium Alloy Housing CNC machined · 54 × 26 × 10 mm Full CNC-machined aluminium alloy enclosure Excellent RF shielding, reduces interference Passive heat dissipation for sustained operation Compact 54 × 26 × 10 mm — pocket-sized Robust construction for field use Aluminium · RF shielded · Compact USB-C Interface Modern reversible connector USB-C connector — no more wrong-way plugging Compatible with modern laptops, tablets, and SBCs Works with USB-C to USB-A adapters Plug-and-play on Linux, Windows, and macOS USB-C · Reversible · Plug & play Applications Aviation & Marine ADS-B, ATC, AIS tracking ADS-B aircraft tracking (1090 MHz) Air traffic control voice (118–137 MHz) AIS marine vessel tracking (162 MHz) ADS-B · ATC · AIS Weather & Satellites NOAA, GOES, Meteor-M NOAA weather satellite imagery (137 MHz) Meteor-M2 LRPT weather images GOES geostationary satellite data NOAA · Meteor-M · GOES Signal Intelligence Spectrum analysis & decoding Trunked radio system monitoring ISM band & IoT signal analysis Pager decoding (POCSAG, FLEX) RF spectrum scanning & recording Spectrum · Decode · Monitor ⚡ 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.
