This amplifier is perfect for increasing the reception of an RTL-SDR dongle. It just about covers its entire tuning range, and then some. I've mainly been using it for shortwave where it has dramatically increased the number of channels received. It's also proven itself well on FM (just don't overdrive the SDR frontend!) and other bands.
Just one caveat: you'll need to BYOP (Bring Your Own Power) as its DC-blocking capacitors prevent it getting power from the coax. A nine-volt battery should do the trick however. Interestingly enough though, the amplifier ("N02" INA-02186 perhaps?) is designed to take bias-T power on its output pin (7V max), meaning that those adventurous enough to make some slight modifications might just be able to power the amplifier straight from the RTL-SDR!
As mentioned before, this amplifier performs quite well and can in fact attain its advertised +30dB gain. However, do note that, like any other LNA, it will amplify the noise floor somewhat as well.
In summary, this amplifier is ideal for anyone wanting an inexpensive upgrade for their RTL-SDR.
