Anons have been speculating that a massive ELF antenna with significant power would be needed to alter the schumann resonance. Eric Hecker, ex-Raytheon employee states Antartica has an ELF system, as well as massive power capable of operating a green laser. The green laser has been confirmed on the south pole webcam.

Hecker revealed to Dr. Michale Salla in an interview that “each DOM has the capacity to transmit at 2047 volts, which, in my opinion, makes it the world’s largest phased array transmitter. This discovery led me to research and connect with Dr. Greer, as it aligns with the concepts he presents regarding directed energy weapons and communication devices for ships traveling faster than the speed of light. I believe this detector serves as the communication device for intergalactic communication.”

“There’s an ELF system at the South Pole station. When I arrived, I was told it was off, dismantled, and completely defunct. In my work, I had to figure out the circuitry for certain other repairs, and I found that this system is, in fact, completely energized, up and running, and being utilized with the other systems for nefarious purposes as well,” Hecker said.
