What if JB put a big loading coil in the fence wire? I would think that 
would work just like our loaded short verticals...Sure there would be 
losses but we have losses in our transmitting antennas also.

J.B. ,

I simulated the fence wire with MMANA.
On HF (80m, 40m) I got the expected (bi)directivity and low offset angle. But on 500kHz the horizontal pattern is almost omnidirectional and the offset angle is 78 degrees. It seems that (at least in theory) even 1200 foot is too short to be long on 500kHz ...
Or does MMANA not work properly ?
