RTL-SDR Blog’s ADS-B LNA

I have dump1090 setup doing ADS-B decoding on a Raspberry Pi using a nice PCB 1090MHz dipole.  It enables me to see a ton of plane traffic overhead.  It serves no real purpose other than it’s something neat to look at.  From my research I felt I should be picking up a much wider view of the sky than I was, and sought out ways to improve.  The antenna certainly seemed good enough.  That’s when I saw the LNA add-on available from rtl-sdr.com.  The difference is startling, honestly.  See for yourself.
