Damn, this ADSB preamp

Why is this so good?
And why does it feel even better when one looks at the Uputronics preamp prices?

Test location, 40 feet of concrete 180° behind the FA antenna with the rtl-sdr v3 dongle + adsb preamp. Poor location.

You can see the antenna deaf spot between 95° and 140°.
This is off the chart performance for me.

4 contacts at 420 Kms!
I can't wait to move the setup to it's final location which has good height and no real obstructions.

Thanks for trying our LNA! Our LNA was designed for really noisy environments, so if you happened to be getting overload from interferers with previous hardware, then our design would improve performance a lot.
