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.
