These DVB-T dongles have new-found popularity since it was discovered they can be used as very inexpensive software defined radios.
Since these are based on the Elonics E4000 tuner IC they have a very large tunable range of 64-1700MHz.
The connector type on the antenna and USB board is PAL aerial.

Unlike many of the more expensive software-defined radios (SDRs) products on the market, these ultra-cheap RTL-SDRs don't even require a high-end sound card for the IF signal processing and they allow you to view a huge 3 MHz band segment in real-time. Pretty amazing stuff! I don't find the 8-bit A-to-D converters in these cheap RTL-SDR dongles to be that much of a drawback. The quality of the signals are good enough to my ears.
Be aware that you will need a proper Euro-style coax adapter for this particular RTL-SDR dongle (RadioShack carries them) and you can forget about using the small wire antenna that comes with this unit. They're worthless. Put up a decent outdoor VHF/UHF antenna with a low-noise preamp hooked up next to the antenna mounting base. I'm using a +16dB low-noise VHF/UHF preamp from AntennaCraft that cost around $30 and works fine for this purpose. Feed the outdoor antenna with some good quality quad-shielded coax. My VHF/UHF antenna is a TRAM 1620-HC 8-Ft VHF Marine antenna with the base screwed down to my wooden deck railing on the second floor of the house. This vertical marine antenna sells on Amazon for about $45.
One thing you need to be be sure to do when operating these RTL-SDR units is to vary the gain factor (slider) in your SDR software. Using too much gain on either the software (slider) side or hardware (antenna preamp) side can cause the signals to get worse, not better! Observe the real-time spectrum and see what gives you the best signal-to-noise ratio (SNR).
One last thing.... in addition to this cheap $32 E4000-based RTL-SDR USB dongle, I also ordered an even cheaper $20 R820T-based RTL-SDR from NooElec. The cheaper R820T-based RTL-SDR dongle is actually a better unit. It doesn't have the huge DC signal spike in the middle of the spectrum that is present on this slightly more expensive E4000-based dongle and the sensitivity of the R820T-based unit is just as good, if not better.
Properly set-up and tweaked, these ultra-cheap RTL-SDR USB dongles receivers are truly amazing! I'm seeing less overloading (intermodulation) issues with this cheap RTL-SDR dongle that I see with my much more expensive GRECOM PCR-310 scanner. If you are into radio experimentation you should definitely try out one of these RTL-SDR USB units. The VHF/UHF performance is way beyond what I expected for this extremely low price. It does require some careful tweaking and is not "plug-and-play" but that's part of the fun. I use my ultra-cheap RTL-SDRs to listen to the aero-bands, police, fire, microwave radio links, satellites, FM-band, etc. It's a wonderful intro into the new and exciting world of software-defined radio (SDR).
The unit arrived quickly as was straight forward to setup. I decided to use SDR# [...] and found reasonable setup instructions. I was able to get this working both on an older XP Desktop with 512M RAM and a newer Win7 Laptop with 2G of RAM. It runs better on the laptop, of course.
I was also able to follow these instructions [...] and get this device working with my Nexus 7 Android Tablet.
I am very happy. I have no idea what the performance of this is compared to others, I am just excited it works and gives me an avenue to start the adventure
