LNA4All Low Noise Amplifier Review

Over on the SDR for Mariners blog, author Akos has reviewed the LNA4All low noise amplifier. The LNA4All is a 25 euro amplifier designed to improve the performance of the RTL-SDR.

His results show that the LNA works very well. Akos tested the LNA4ALL on multiple frequencies and applications including commercial radio, airband, NOAA weather satellites, AIS and ADSB. As an example of the improvement, his ADSB reception was improved from 83km to 94km. In his review Akos also shows how to provide power to the LNA, and puts the LNA through some simple stress tests.

Some are also using cheap satellite boosters (after modding these by cutting tracks so power will be not feed into dongles and into antenna) for this purpose. Unfortunately no idea how these compare to lna4all.


There were an another option in the RTL-SDR group, here is the datasheet: Datasheet

I’ve researched the available options before ordering the LNA4All and writing the review, available options are either in a kit (I can but will not solder) or have higher noise figures.
LNA4ALL works, and works well. (and no, I have no affiliation with the seller)


Here is a cheaper version, 25 euro is a lot. Ebay Link


That`s correct, other item is assembled and that`s a plus. Have you tested this one as well ? The 25 euro LNA ?


Yes, it’s very handy to have one of these, but 25€? You can make one yourself for just a few dollars! The main component is a MMIC amplifier. And the circuit is very simple.
