Pros & Cons
Pros
Highly recommend this. I have it wrapped up in a sandwich bag to keep moisture out. Works well and would recommend.
Works as advertised, former weak signals are now very readable.
Cons
Some of us have no tools or adapters and can't solder and software development for this type of system is too hard on an android. Returned for refund. Couldn't resolve bias t software necessity so couldn't even test.
Highlights
Quality
This lna works well small lightweight and conveniently powered via biastee perfect for remote installation at the antenna
A great feature of this amplifier is the addition of overvoltage protection to the input
This lna is easily damaged from electrostatic discharge and should have esd protection at its input if used with any antenna wh... Read More
The static will reach a point where it can arc across and burn out the amplifier chip
Price
I am very glad i added this affordable lna to my collection
Beats paying hundreds for a dedicated scanner that would do a lot less

I sealed it inside a small plastic box

Didnt really improve some signals while others it coaxed out of nothing

Based on the spf5189z rf amplifier ic this device essentially mimics the data sheet specifications according to my tests
Posted by a reviewer on Amazon
I tested it over a voltage range of 3 to 5 volts and it works as advertised although the gain starts to fall off by a little less than 1 db from 3 to 3

There is a esd suppressor diode and that is followed by a dual diode in a back to back configuration

Edit i added a photo and some rf tests i made
Posted by a reviewer on Amazon
The rf gain shows the measured gain and the input swr shows the measured rf input swr
Posted by a reviewer on Amazon
Note on a receiver the input swr is not all that important and a lna by definition will have a less than perfect swr because it is matched for low noise instead of optimizing the swr also the inclusion of the input protection will degrade the swr
