 Otherwise you'll need a suitable SDR radio (probably an RTL-SDR or similar designed specifically for ADS-B reception) and a suitable Linux system for feeding. This is usually a Raspberry Pi, but it can also be run on normal Linux machines. We'll only cover RTL-SDR-based installs here as that is by far the most popular setup, but you may be able to use other radios with technology such as Soapy SDR or extra drivers. Otherwise you'll need a suitable SDR radio (probably an RTL-SDR or similar designed specifically for ADS-B reception) and a suitable Linux system for feeding.

 For an antenna you can make something really simple or buy something. A simple 1/4 wave ground plane built around a chassis connector for 1090 MHz connector works well, as does a collinear made from coax segments inside a PVC pipe. Feed the antenna with good coax with decent loss stats at this frequency. You can use cable TV 75 Ohm coax at a push and the loss stats are quite good @ 1090 MHz. For an antenna you can make something really simple or buy something.

 There are detailed instructions for the OARC feeder and MLAT clients on the GitHub repo, and the process is  quite automated and prompt-led. You shouldn't need TOO much support as long as your SDR works ok. Useful troubleshooting can be done by checking your system journal/log for messages relating to the loading of the drivers for SDR, as well as commands like lsusb to check connected device status. There are detailed instructions for the OARC feeder and MLAT clients on the GitHub repo, and the process is  quite automated and prompt-led.
