The Eltanin Antenna is a long pole shaped object several meters long based in the Antartic depths of the sea. Short little poles with round shaped objects are at each end. Whats the big deal?

These are the questions that are brought along the Eltanin Antenna. Here is a picture of what the Eltanin Antenna looks like:

This is a real copied image of the Eltanin Antenna deep in the Antartican floors.
