there was a vlf experiment done in the USA http://qru.de/w4dex-vlf.html , 
that used a big loop mounted to power line poles (below the power line of 
course). they got 10km from abt 100W. this is very similar, but the 
coupling loop is isolated. using a loop between the towers is easier - i 
haven't tried that.
btw. i have an international gas pipeline nearby:

opportunity for dx maybe? :)
