RTL-SDR BLOG V3 USB Dongle with Dipole Antenna Kit

Added to your shopping cart

The RTL-SDR BLOG V3 is a low-cost software defined radio USB dongle. Perfect for getting into projects that utilize software defined radios or just learning more about them.

The RTL-SDR Blog V3 is an improved RTL-SDR dongle. RTL-SDR dongles were originally designed for DVB-T HDTV reception, but they were found by hardware hackers to be useful as a general purpose SDR. The standard dongles are okay for DVB-T reception, but are just barely suitable for SDR users/experimenters. The RTL-SDR Blog V3 was redesigned with SDR user needs in mind, instead of DVB-T HDTV users who typically have more relaxed requirements.

RTL-SDR works hard to maintain a higher standard of quality for the BLOG V3 among the other entry level SDR dongles on the market such as upgraded antennas and an Aluminum case for better cooling. With a bandwidth up to 2.4MHz and a frequency range of 500kHz - 1766 MHz it's a capable SDR at a great price.

This kit includes the BLOG V3 USB Dongle and the RTL-SDR VHF/UHF dipole antenna kit. Great for beginners as it allows for terrestrial and satellite reception.

    Works great for decoding ADSB data from aircraft. Also works well for receiving air band comms. Haven't been able to receive AM broadcast stations but that's probably a setting I have wrong.
