Hi Alex,

very interesting, thanks for your information. The challenges in my
case would be keeping the kangaroos, wallabies and wombats away from
the wires, but at least the temperatures are a bit more pleasant :-)
My place is also very undulating, the highest from the lowest point is
about 80 m difference in elevation. This makes me think that a wire
from the bottom to the top will have some respectable vertical
component. Of course there is the proximity to the ground which will
mess things up, but perhaps it is worth a test.

73, Dimitris VK2COW
