Gap Jumping Antenna Out of US Embassy in Moscow

Artifact Details

A metal antenna protruding from a small piece of concrete

The concealed location and magnetic connection kept the antenna from being discovered.

What looked like a concrete ball was actually a “gap-jumping antenna” removed from one of the preformed concrete columns in the embassy office building. US investigators called it “gap-jumping” because it coupled magnetically with a matching antenna in the adjacent column. This allowed data to be transmitted without a physical electrical connection.
