Includes 2pc NESDR Nano 2+ SDRs. Each SDR is lab-calibrated and EEPROM-programmed for simple Stratux setup.</br>Each NESDR Nano 2+ includes a high-quality 0.5PPM TCXO. This ensures tuning stability even in extreme temperature conditions (like those which occur in an airplane cockpit).</br>Each SDR includes a calibration sticker and identification labels.</br>4 ADS-B antennas 3 RF pigtail cables and 2 RF adapters are included to facilitate a very wide range of installation options for embedded applications.</br>Full 2-year warranty through NooElec on all bundle components.</br></br>Product Description</br></br><p>This dual-band SDR bundle contains everything you need for a full DIY ADS-B installation. <p>2 NESDR Nano 2 Plus SDRs are included. These SDRs contain an R820T2 tuner along with an RTL2832U USB interface/demodulator. They also contain an ultra-low phase noise 0.5PPM TCXO. This very high accuracy clock ensures the ultimate in tuning stability even in extreme environments. They have a frequency capability of approximately 25MHz-1700MHz. The NESDR Nano 2 Plus are very small in size which makes them perfect for portable and embedded applications. <p>Each SDR is lab-calibrated and serialized for easy 'plug-an
