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?

• Military Communications: From Ancient Times to the 21st Century talks about the Wisconsin Project Sanguine antennas being 14 miles long and mounted on 40 foot poles. This was for 76Hz. These were in some sort of array and connected by 165 miles of cable (this info can be read in the book extract on Amazon!). 
• ELF Communications Antennas by Burrows is an IEE publication that must contain some useful information.

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:

or in german

http://de.wikipedia.org/wiki/Funkstation_am_Herzogstand (more detailed and with a picture of the antenna construction)
