Long antennae for LF and VLF?
At the risk of doing oneself an extreme nasty, I wonder if one
could couple the RF into the national Grid by having a coupling
coil a few feet below the dangling 400kV cables?
(Obviously not a direct connection beacuse that is specifically
forbidden in Brit licensing laws :-) )
However, ISTR from 40 years ago working on the automation of
the Brit National Grid that pilot protection operates on LF somewhere
so perhaps there would be a danger to the grid itself?
(Pilot protection - send RF along the cable, and if it doesn't arrive
at the other end, then wire must have broken)
