Hi Group
 
Perhaps not so grand as Herzostand Station but WT Station Criggion was build in a bit of a hurry and used the side of a Welsh "mountain" as the far end achorage of the 16kc/s Antenna. Before its destruction in 2003 the station was entered via a Hanson slate quarry. I had the fun of working there not many years before that on a few occations adding 21st century EMP proof Fibre optic communication to a TX that use massive thermionic Valves!
 
But as with all V / LF stations most of the RF went into the ground anyway.

I agree about the Wiki antenna: it is strung between the mountains, not using buried electrodes.

Maybe we dreamers need to consult some textbooks on ELF/VLF antennas?  Another data source should be any publicly available papers about Project Sanguine antennas. IEEE Antennas and Propagation may have had some references in the 1970s or 80s?
Unfortunately these can be expensive to buy but I may be able to read copies at the University Library here in Cambridge.  Usually such texts are highly mathematical whereas what I need is a good overview which could be easily grasped without too much maths.

Hi Roger, VLF,

Today Markus gave me the hint of an (at least for me) most interesting article in wikipedia. 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)
