The Nano 3 is built into a high-quality brushed aluminum enclosure. This RTL-SDR was designed into a tiny form factor to ensure proper fit within the smallest USB-compliant spacing. Quad SDRs on a Raspberry Pi? USB OTG? Not a problem for the NESDR Nano 3! No more blocked USB ports! The Nano 3 is just 17mm x 8mm x 20mm weighs only 15g! An articulating, right-angle female SMA connector is included to allow you to attach both male SMA and male MCX antennas directly to your SDR. The ultimate SDR bundle for USB On-The-Go applications. Includes NESDR Nano 3 in an anodized aluminum enclosure, nano-sized antenna, 3x USB OTG... Full compatibility with a wide variety of popular SDR software packages, such as Matlab, CubicSDR, HDSDR, SDR Touch, Planeplotter for Windows, Mac, Linux, Android & Raspberry Pi. Good Directions.

We are so confident of the reliability and stability of this SDR that we offer a full 2-year warranty--the longest in the industry. This is by design, and will not affect performance of the SDR. A custom heatsink, which can optionally be affixed to either side of the SDR to further improve heat dissipation, is included with your purchase. CAUTION: The enclosure will get hot! The latter is especially important in EMI sensitive environments like automotive and flight applications! The included articulating SMA connector allows for connection of both male SMA and male MCX antenna types without additional expenditures The industry-leading 0.5PPM temperature-controlled crystal oscillator (TCXO) ensures that you will always be able to find the signal you need with absolute minimal drift and jitter Say goodbye to blocked USB ports! The high-quality aluminum enclosure and silicone pads ensure that heat and stray EMI stay where they belong This RTL-SDR is based on the R820T2 tuner IC made by Rafael Micro, which means an approximate tuning range of 25MHz-1700MHz .
