It is about a "earth" antenna like we have it in principle and it shows that it can indeed compete with a traditional= marconi antenna. Maybe you know that since 10s of years but for me it was new: http://en.wikipedia.org/wiki/Herzogstand_Radio_Station or in german http://de.wikipedia.org/wiki/Funkstation_am_Herzogstand (more detailed= and with a picture of the antenna construction) 73, Stefan/DK7FC
