The J-pole was first used by the US Navy in WW2. It was used for a
special radar on submarines. They Would come up to periscope depth in
enemy waters and take a quick look with this radar and its
"omni-directional", j-pole antenna to see if any airplanes were in the
vicinity! Of course I don't have the model numbers, but that's where I
saw it first in 1942 at the Pacific Fleet Radar School in Pearl Harbor.
