Thread-topic: VLF QRP Earth mode: 5.1km DX tonight but no such thing as a free lunch
Yet another thought:
 
salt water is a rather good conductor.
What about a couple of rods into the sea near Dover and another pair near Cap Griz Nez ?
Distance is 34 km.

  1. At greater distances (3-5kms) the signal reaches its destination by conduction through the ground aided by pipes in the roads and with inductive coupling into the loop at the RX.
Roger,
 
very interesting.
There are huge gas pipelines running across the country (and even across Europe).
I wonder how far one would get with a ground antenna near one of these.
The 2 rods of the ground antenna each at one side of the pipeline would give optimal coupling.
