LF: Re: VLF earth antenna article in wiki

Hi Stefan, that is an interesting note. Unfortunately the English version
needs a clean up but it is understandable. Unfortunately there is not a lot
of detail about the use and equiment installed.

I think this is not an "earth antenna" but is a mountain supported "T",
though is seems to have quite a slope.  Similar antennas were used at
Criggion GBZ (which was built a a standby for GBR Rugby but now closed and
disassembled) and Jim Creek (NLK, and still transmitting on 24.6 kHz I
think))  for VLF transmissions. Jim Creek was used for Omega transmissions
up to about 1990 and has been well written up in the "Lowdown"
journal/newsletterl of the Long Wave Club of America. Articles on Criggion
(Practical Wireless) and Jim Creek describe massive concrete anchors points
on the mountain peaks for the support wires.

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)
