These DVB-T dongles have new-found popularity since it was discovered they can be used as very inexpensive software defined radios.
These units are based on the R820T tuner IC made by Rafael Mirco. There is also an RTL2832U IC on board of course, which allows for interfacing to a large number of popular SDR software packages.
The connector type on the antenna and USB board is MCX.
What Other Items Do Customers Buy After Viewing This Item?
I actually bought mine from NooElec's website directly, but it's the same exact product they're selling here.
I bought this as an SDR (Software Defined Radio) instead of as a DVB-T receiver. I'm in the United States where we don't have DVB-T stations, so I can't comment upon its performance there. However, as an SDR, it's quite amazing. And that's before you realize it's twenty bucks! I'd gladly pay $100-$200 for this thing. I've only had mine for 4 days, but so far I've been able to pick up local HAM radio repeaters, a few 2-way radio conversations, FM radio stations, NOAA weather radio, and am currently using it for ADS-B reception and am uplinking to FlightRadar24.
A few tips for beginners: 1) This comes bare-bones. Hardware only. That's good in a way, as if you're using it for SDR, you DO NOT want to use the DVB-T drivers. 2) This is an off-label use for this device. It was NEVER intended to be used as an SDR. Keep in mind that prior to February 2012, all these USB sticks were good for was watching TV in Europe. The drivers and software are a work in progress. This is what I call bleeding edge technology. Some of the software is very refined & polished; other parts have been cobbled together & borrowed from other devices. With patience, you can get a very reliable and very functional rig from this. 3) When in doubt, Google is your friend. Search for RTL-SDR + whatever terms you're having trouble with or curious about. We're all still learning what these devices can do. 4) FWIW, you can use multiple USB sticks on one computer. Why would you want to do this? UniTrunker, running ADS-B + ACARS simultaneously, monitoring multiple frequencies, you name it. I don't know of anything out there this flexible.Read more ›

I picked this up in addition to an E4000 version. This one is generally better. The bottom end of this is in the 37MHz range. Don't expect to pick up long-wave or AM broadcasts.
Picking some lower-end areas will either show up silent, with strange device noises, or maybe fail to open the device with libusb0.
I can pick up ADS-B really well with this. Higher elevation and better antenna helps too, but this blows away the E4000 even with a favorable gap.
Sensitivity is pretty good with this, and so FFT contrast is good.
Also, trying kalibrate, this varies by as much as 22khz from reliable sources. That's mostly thermal issues on the low quality oscillator, however, I found this to be more consistent than the E4000. This was -22kHz, plus or minus 1kHz. That's pretty easy to work with. If it's not just because of where I'm sitting temperature wise, this might even sync with GPS on RTL-GNSS for those more daring, but it won't pick up PCS or higher freqs.
This is generally a decent device. Sensitivity is better than decent.
This has a very small antenna port, sort of a micro-pal connector. I haven't been able to find adapters to hook up other antennae to it.
The alternative is an E4000 device, which I find to have better high-end range, but poorer sensitivity, and worse reception of aviation/radar signals such as ADS-B.
I recommend picking up SDRsharp, because it just works. Run the "zadig" tool to associate your RTL device with WinUSB. Start SDRsharp and go into "Configure". Turn off RTL-AGC manually set tuner gain to 36dB. Set to an FM station, and use "WFM". Hit "play" and tinker with things until you're happy.Read more ›

Lots of great reference sites out there on this TV dongle showing how to enable a truly broadband programmable receiver. (see [...]as a great starting point)
NOT FOR RECEIVING TV IN THE USA
It works great with the current drivers and SDR# software on my XP desktop. The antenna is very short so do not expect any serious performance unless using something more substantial. The MCX antenna connector is hard to find, but my next step will be to mount this in a small box and solder a cable to a BNC connector. At less than $20 for the entire dongle package it would be crazy to spend as much or more on expensive connectors!
Works fine on local FM stations and some Public service activity too. No success yet on 1.09GHz ADS-B signals, but that may require a better antenna. Way cheaper than a Funcube dongle and great fun so far.
Lost one star for apparent low sensitivity on broadcast FM band, but otherwise I am happy to recommend to fellow experimenters, HAM radio or scanner listeners.

There are already a lot of positive reviews of this product. Therefore, if you're hesitant about dropping $20 on a really cool gadget at this point, I can't help you. However, I would like to mention my particular use.
I am researching an established radio-based protocol. I'm trying to characterize the types of interference and real-life signals involved (not just what the spec says). Until I found this gadget, I was working with other engineers to develop a simple capture system just for research. Even though this doesn't have the sensitivity and resolution I will ultimately need, this got me out of the pure theory stage, and working with real signals. And, I'm not spending other people's time building temporary hardware.
I want to also point out just how educational this can be to any aspiring or current electrical engineers. Using any of the free SDR programs gives you a pretty amazing perspective of the RF spectrum. My past experience with receivers has been tuning to known frequencies, and seeing what you get. Using a tool with a live FFT and waterfall display gives you a visual "browser" into the RF spectrum. It's really cool to see the channelization in the commercial broadcast bands.
