    Sure, it's not only the antenna. The whole setup must fit.

    And it depends on your environment.

    With that antenna, i'd say the antenna is the problem.

    You can try extending it to 13 cm and see if that helps.
    Most likely it doesn't.

    If you are not using it for anything else you can just cut it at 6.7 cm

    I guess it really was antenna+dongle all along.
    I tested with an RTLSDR blog v3 and immediately started finding airplanes!
    In the first minutes after reboot, 3 airplanes in a 20nm radius.

    I guess I must order another dongle since I used this blog v3 to remote monitoring other frequencies.

    See these recommendations:

    If you don't want an external LNA, getting a stick with internal LNA and filter for 1090 MHz is very nice for reception.

    (Flightaware ProStickPlus or Radarbox green FlightStick)

    I started directly with the bule Flightaware Stick (pro plus).
    Even with my indoor antenna, i am almost on the max geographic range.

    As wiedehopf already suggested you can get an external LNA for your dongle
