Testing for signal lines

[Clondike Clad]

Ok what frequency and output power for the signal lines sand how do we detct it.
If we inject a signal into the ground how do the L rods pick them up and how do we know it is picking them up.????????????????????
At this time I can't get any LRL to work or picl up any signal.
If we can generte a signal we can detector it. but what signal?????????
