Hello Mark,
200W in such a loop and 8.97 or 8.27 kHz, CW, my guess is that the
distance is less than 2 km. But it depends on the type of the RX
antenna (E or H field).

Hi -
I've been following the discussion on
9 khz transmit antennas with some interest, as a friend of mine, Tom,
KD0VBR, has done some preliminary experimentation in this area ( using
large loading coils w/ vertical ). Tom asked me to post a query
regarding some antenna ideas he has, and it would be great to hear the
group's thoughts on them and whether they might work or not. 73, Mark

Hi Mark,
That would be great if you could
post some questions about transmitting loops for VLF.
Thinking about a square loop 200'
per side 10' off the ground #8 wire with 200 watts into the antenna.
How far away could one expect to be able to detect a CW signal ? ( not
QRSS)
Another possibility would be a
triangular loop 200' per side with a 50' high apex.
