- Eleduino Store: http://www.eleduino.com/Aluminum-Case-for-ADS-B-Raspberry-Pi-Stratux-DIY-Kit-Black-p10625.html
- latest version of this case includes a fan - certainly a good alternative but instead of the fan, passive cooling with custom aluminium blocks as described below is still possible
Hammond Case (standard aluminium case, needs more mechanical adjustments, Pi board needs to be mounted upside down)

- Prodrone: https://shop.prodrone.pl/en_US/p/ProFlex-Vee-868Mhz-915MHz/179 (make sure to select the appropriate frequency and connector)
- GliderDesignParts: http://www.gliderdesignparts.de/ant_flarm.en.html
- Prodrone: https://shop.prodrone.pl/en_US/p/ProFlex-Vee-868Mhz-915MHz/179 (custom order, you specifically need to order 1090MHz)
- GliderDesignParts: http://www.gliderdesignparts.de/ant_adsb.en.html
- all antennas need to be oriented vertically, in case of ProDrone and GliderDesignParts one antenna leg vertically, the other one horizontally
- only the Taoglas and the Nooelec bundle antennas are hinged so make sure to order an SMA adapter (angled) for all other antennas according to your needs
- both ProDrone and GliderDesignParts antennas can be custom ordered with either a straight or an angled SMA connector
GNSS (some mechanical adjustments required to the Eleduino case side cover so that the USB plug fits, a M5 rubber grommet is recommended)
