Tesla Magnifying Transmitter With Various Receivers-01 - YouTube
Nothing is even set up properly. The pile of junk dangling in mid-air is an amplifier supplying approx 367mW of power to the single turn test coil. The ground plane beneath the transmitter (and consequently the transmitter and the transmission line) is connected to house mains earth, it doesn't like it with better grounding with such detuned receivers. The receivers become more sensitive when better tuned, nothing had been done prior to the video in terms of properly tuning any of the coils, not to mention none of them are designed for the same frequency.
Receivers tested:
Tesla "test coil"
Eric Dollard flat spiral (as Borderland video)
"Colorado Springs"/Eric Dollard CRI 20 turn secondary
