I enjoy reading far out theories like these. I recently[1] saw one that claimed all the weird tunnels that terminate just short of the outside resemble wave guides, the big tunnel with the grooves was a low pass filter and the whole structure was basically a giant antenna

Any electrical engineers around feel like modelling it seeing how true it is?

You wouldn't make an inverted-inverted-V antenna out of waveguide. The whole point of waveguide is to be a transmission line, not a radiating element. Even if we ignore that, a dipole antenna of those dimensions is two orders of magnitude larger than what you'd use to radiate on the hydrogen line.
