Hi Joe,
Can you reach them from the shack or would it need to be a portable
activity to make use of them?
What do you think about the ground conductivity?
Where will that loop point to?
Remember, there is W1VD and Paul N. who certainly will be able to detect
the weakest signals! As soon as they did, you will have a good
comparison to your conventional wire/coil antenna.
Buy some thin and cheap wire for frst tests. And as a pre-test, take a
20W / 12 V bulb and a small 12V accu and switch it in series to the rail
and each pole, and between all rail segments, to check if they are
actually connected to each other. If so, then this is a good first sign.
Imagine, i got 64 Ohm DC today, and the wire has about 50% of that. So
it means that the resistance of both guide rail electrodes plus the soil
resistance over that 900m distance is just 30 Ohm!
I bet you will make it over the pond below 8.27 kHz and you don't even
need to wind a coil for that, or deal with high voltages. Even the wind
will not cause any trouble. What do you want more? :-)
Oh, and a H bridge switch mode PA will handle 1 kW easily!! I have a
quite small heat sink and it stays completely cold! :-)
Great stuff i can tell you!
Make your peace with mother nature. :-)

There are guard rails here that run in a straight line for about a km
that would make fine ground loops for VLF but getting across the pond
might be challenging.
