RTL-SDR Blog V4 RTL2832 1PPM TCXO HF BiasT SMA Software Defined Radio + Antennas

• 1x RTL-SDR Blog brand V4 R828D RTL2832U 1PPM TCXO HF Bias Tee SMA Dongle
• 1x Dipole antenna base with 60cm RG174
• 2x 23cm to 1m telescopic antenna
• 2x 5cm to 13cm telescopic antenna
• 1x 3m RG174 extension cable
• 1x Flexible tripod mount
• 1x Suction cup mount

This RTL SDR unit has several improvements over generic and other brands including:

• R828D tuner
• Improved passive component tolerances
• A 1 PPM temperature compensated oscillator (TCXO)
• HF mode via built in upconverter
• SMA F connector
• Aluminium shielded case with thermal pad for passive cooling to improve L-Band performance
• Software activatable 4.5v bias tee circuit
• Improved power supply and PCB design for lower noise and less spurs
• A USB noise choke, more bypass capacitors, and built in ferrites for less PC noise
• Improved ESD protection (additional ESD diode and extra ESD discharge paths)
• An improved front end circuit designed for wideband use (other models still use a circuit designed for DVB-T only)
• Improved front end filtering via triplexer
• Several breakout pads on the PCB for advanced users

This is an RTL-SDR Blog V4 software defined radio receiver with RTL2832U ADC chip, R828D tuner, 1PPM TCXO, SMA F connector and aluminium case with passive cooling. Tunes from 500 kHz to 1.7 GHz with up to 3.2 MHz of instantaneous bandwidth (2.4 MHz max stable, 3.2 MHz if your application is tolerant to USB drops). Perfect for use as a computer based radio scanner with free software like SDR#, HDSDR, SDR-Radio, Linrad, GQRX or SDR Touch on Android. Works on Windows, MacOS, Linux, Android and even embedded Linux computers like the Raspberry Pi. 

The Dipole antenna kit is perfect for helping beginners get great reception. The short antennas are great for ADS-B, and the longer antennas work well at the lower frequencies. When used in a V-Dipole configuration the antenna is an excellent option for 137 MHz satellites such as NOAA/Meteor M2 weather and the ISS. In the vertical configuration it is great for terrestrial signals. The two mounts allow you to easily mount the antenna outdoors for best reception. Please note that you should not use the antenna permanently outdoors or during bad weather. It is designed for portable temporary outdoor use. For using custom antennas note that this dongle has an SMA F connector (not RP-SMA).

This model has several key improvements over other models. It uses the improved R828D tuner, has a 1PPM TCXO (2 PPM initial offset, 1 PPM temperature drift), has improved component tolerances and an SMA F connector. It also comes with a software activatable bias-tee circuit for powering external devices such as LNA’s and active antennas. It also has HF reception capabilities. Most standard RTL-SDR dongles can tune down to 24 MHz at the lowest. This model has a built in upconverter, and allows for tuning down to 500 kHz. There is a built in 28.8 MHz low pass filter for optimizing this mode.

Requires USB 2.0 (works on most USB 3.0 ports). Installation on Windows is simple, please Google for the RTL-SDR Blog Quickstart guide
