Dear Eberhard,
thank you that you like using our webSDR! The antennae we use for the reception of meteors are as follows: on 2m we use a 5 element homemade 28 Ohm Yagi after the DK7ZB design. It is on a pole at 10 meters above ground level. The antenna is approximately 10 to 15 degrees tilted upwards and bearing south to the direction of Dijon where the GRAVES radar is.
For the 6m reception we use a single 3 element homemade 28 Ohm Yagi also after the DK7ZB design.This antenna is on a 5m high pole and also elevated for 15 degrees and bearing south south west mainly for reception of the Ypres VVS beacon. Because of the 3dB aperture of the 3 element Yagi the BRAMS beacon at Dourbes can be received simultaneously without noticeable loss of efficiency since the azimut angle between both beacons seen from Dwingeloo is not too far apart.
In 2018 i gave a presentation on our webSDR meteor receiving system at the EURACA conference at Astropeiler Stockert in Germany.You can find more info and pictures on this url:

I also recommend to read Frans de Jong PE1RXJ his presentation on the same site about the results with meteor scatter reception with our webSDR setup.
Since then we have updated the receiver with a separate GRAVES receiver via a Funcube dongle tuned to 143 MHz. Alongside the 2m RTL SDR dongle that was set to cover the whole 2m amateur band in order to be able to receive satellites as well. Also recently 23cm EME has been added to the existing 70 cm EME receiver both also with RTL SDR dongles.
I hope to have informed you sufficiently on how our setup is. It started as a small experimental setup but it has been successful online for several years already.
