This premium RTL-SDR was designed, developed and fabricated by Nooelec in the USA and Canada. It allows you to turn your computer, phone or tablet into a radio scanner/ham radio receiver that can receive nearly all RF signals! Compatible with Windows, Mac OS, Linux, and Android. The best-performing low-cost RTL-SDR available anywhere! Compared with RTL-SDR v3, HF SNR is improved by up to 15dB, VHF & UHF SNR is improved by up to 6dB, tuning accuracy is improved by an average of 4x, and the frequency range is expanded all the way down to 100kHz v5 has a frequency capability of 100kHz to 1.75GHz and up to 3.2MHz of instantaneous bandwidth. HF reception below 25MHz is accomplished with direct sampling and requires a suitable antenna. We recommend using a Balun One Nine to make a DIY long wire or dipole antenna (sold separately, product ID B08HGSYB7R or B00R09WHT6) With a much narrower form factor than RTL-SDR v3, you can run multiple NESDR SMArt v5 side-by-side with any USB-compliant device, including tightly-spaced embedded devices like the Raspberry Pi For full product specifications, please visit our website at nooelec.com, or download the datasheet: https://www.nooelec.com/datasheets/100701 Included: ✓ NESDR SMArt SDR in black brushed aluminum enclosure SDR Specifications: ✓ RTL2832U Demodulator/USB interface IC ✓ R820T2/R860 tuner IC ✓ 0.5PPM, ultra-low phase noise TCXO ✓ RF-suitable voltage regulator ✓ Shielded primary inductor ✓ Integrated custom heatsink ✓ Female SMA antenna input ✓ High-quality black brushed aluminum enclosure TCXO Specifications: ✓ Frequency stability: 0.5PPM (max) ✓ Phase noise @1kHz offset: -138dBc/Hz (or better) ✓ Phase noise @10kHz: -150dBc/Hz (or better) ✓ Phase noise @100kHz: -152dBc/Hz (or better) See moreFull datasheet available: https://www.nooelec.com/datasheets/100701. Proudly built by Nooelec in the USA and Canada! Full 2-year product warranty and product support through our support portal at https//support.nooelec.com. Your purchase includes a NESDR SMArt v5 RTL-SDR. For a version which includes an antenna set, see product ID B01GDN1T4S. Though the direct sampling implementation of NESDR SMArt v5 is much better than any other RTL-SDR, we still recommend using an upconverter like the Ham It Up for a more fulfilling HF experience (sold separately, product ID B076CYK8XZ). v5 has a frequency capability of 100kHz to 1.75GHz and up to 3.2MHz of instantaneous bandwidth. HF reception below 25MHz is accomplished with direct sampling and requires a suitable antenna.
