What is required:

  • antenna
  • coax
  • SDR / receiver
  • power supply
  • micro sd-card and a Raspberry Pi

See also the budget options which include antenna / coax / SDR in one package.

Antenna choices:

do it yourself antennas:

Coax cable:

USB rtl-sdr compatible receiver choices:

combo of antenna / coax / SDR, not bad

high performance SDR + LNA combo:

best performance for higher price

  • Airspy mini: https://airspy.com/airspy-mini/
  • Always combine with one of the filtered LNAs mentioned in the previous section
  • Airspy mini needs non default software: /~https://github.com/wiedehopf/airspy-conf (supported out of the box by adsb.im)
  • Note that the airspy mini has a current limit of 50 mA for the biastee, consider supplying the LNA via USB if that is supported

cavity filters for best performance or strong RF sources nearby

cheap LNA for 1090

LNA for 978 and 1090, good for use with the adsbexchange dual band antenna

combined and placed before the Y splitter ... into two rtl-sdr v3 or nesdr SDRs should provide good dual band reception.

budget option: antenna + SDR (lower range)

Micro sd-card (others will do, just an example):

or the RPi4, for that get these items:

RPi3 (probably overpriced, RPi4 might be cheaper)

software setup, see this page:
