Hello Horst,
Sorry, for the bugs.
The 2nd JFET is also a BF862, yes.
RG174 is just an example, you can use any coaxial cable or maybe twisted
pair cable.
"This evening" should have been "This weekend". Still not sure about the
wind conds on saturday/sunday.

Hello Stefan,
thanks for posting the circuit.
Is the second FET also a BF862?
Why RG-174?
"cu this evening" - arey you planning a test? I did not here of that.

Betreff: VLF: 8,97 kHz active antenna circuit and pictures
Dear LF,
Daniele and others asked for the circuit of my active E field antenna that i am
using for my grabber. Now i have created a pdf file where you can find the
circuit and a picture of the arrangement and a spectrogram of the currently
working circuit.
http://www.iup.uni-heidelberg.de/schaefer_vlf/8,97kHz%20active%20E%20field%20antenna%20by%20DK7FC.pdf
So, if you are interested or want to get some ideas for your own circuit, take
a look on it. I hope the link works.
So, best 73 and maybe cu this evening there, dreamers.
Stefan/DK7FC
