Thread-topic:	VLF in Canada - earth loop

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 AB0CW

Below are his questions:

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.

Tom
