You say you went 4600 ft ungrounded??? Did you try going to
multiples of the 1/4 wave length(or close) and grounding the
receiver to see if you could pick up the signal again?

I used our model M-150, a 7.5 kVA coil with an 8 ft long spark, to
light up a 10 inch long neon tube using an identical coil as a
receiver --- at a distance of 4,600 feet.
We started out in the driveway, and I was surprised that at the end
of the driveway it was still igniting. I loaded it in a truck and
drove down the road east until it extinguished. Near 3/4 mile range
using coil with identical tuning.
