Again, The output frequency at the probes should be the same as the selected input frequency.
If the wire is not connected to the ground probe, it is unlikely the output frequency from the ground spikes will be the same as the selected input frequency. You are broadcasting the frequency into the air, not through the ground.
But, that's O.K. With the spiral wire configuration you probably have more range by using the Ground probes in an Air Mode. With the probes pointing upward just rest the probes in the transmitter case about 6 inches apart, and set the transmitter on something a couple feet off the ground.
If you are using a correct harmonic frequency for discrimination, your Quad unit should work.
You must understand that Magnetic Interference can weaken the signal field, or totally override it. During such periods your Quad will work intermittently, or not at all. Dell
