The NESDR Mini 2+ is tuned for SDR usage, including a high-accuracy, Japanese fabricated, GPS-rated 0.5PPM TCXO crystal; re-designed RF-suitable power supply; and improved capacitors and inductors compared to generic devices. Power consumption has been reduced while improving sensitivity and lowering the noise floor.
A high quality telescopic antenna and strong magnetic suction mount base included free of charge in order to facilitate a wide variety of antenna mounting options. A free female SMA adapter is also included at no cost for those looking to connect SMA antennas to the NESDR Mini 2+.
The perfect device for learning software defined radio, on the cheap. Amateur radio, ADS-B, police & fire scanning, trunking, satellite images--you name it, this little guy can probably do it. Outperforms many devices 10x its cost!
These units are based on the R820T2 tuner IC made by Rafael Micro. This provides substantial performance improvements over R820T. They have a frequency capability of approximately 25MHz-1750MHz, though this can vary slightly from unit to unit. There is also an RTL2832 (RTL2832U) IC on board of course, which acts as the demodulator and USB interface.
The connector type on the antenna and USB board is MCX--male MCX on the antenna, female MCX on the SDR.
