This sounds interesting. Can you point at any published results to 
explain what technique was used, what power was used to obtain those 
results, and how the signal was launched? I imagine lots of people are 
considering the use of long lengths of metal infrastructure (on private 
land, with the express permission of the landowner), so if there is a 
solution which is demonstrably better, it would save a lot of 
unnecessary trouble for experimenters.

Do you have any numbers comparing the technique used in these 
experiments against those obtained from using long lengths of armco or 
metal fencing or huge bridges, (putting aside any arguments about the 
rights and wrongs).  It would be good to see a documented comparison to 
show by what margin the experimental technique used is superior to using 
low steel structures with a large horizontal extent.
