RTL2832u – R820T VS RTL2832u – R820T2
In the world of Software Defined Radio there have not been many new products introduced over the past year. The products that have been introduced have been a little pricey for what they do. With that being said, there is not much if anything that can beat the venerable RTL2832U dongle as a great low cost introduction to the world of SDR. The R820T variant of the RT2832u dongle has turned out to be a solid performer for entry level applications over the past couple of years. Just recently a new and improved version of the RTL2832u – R820T has become available very cleverly named the R820T2. These new dongles are being made available in the US by NooElec on Amazon for around $24.95.

The first thing you may notice about the R820T2 is that the case is now bright blue and the blue power led is much brighter. Outside of that, the cases of the R820T and the R820T2 seem to be identical in size and construction. They both even share the same antenna connector, so you can continue to use any aftermarket adapters or antennas that you may have purchased for your older R820T dongle. Speaking of antennas, you now get a much improved magnetic whip antenna versus what was shipped with the older R820T. The older antenna was a fixed whip at around 5.5 inches where the new whip is extendable from 3.75 inches to around 12 inches. The new antenna also includes a magnetic mount as well as a tilt mount. The RTL820T also ships with the same somewhat useless remote. just incase you are interested.
