The Conical Log Spiral antenna first came to the attention of
the EMC community when it was listed as the preferred
antenna for radiated emissions measurement in MIL-STD-
826A, 20 Jan. 1964. At the time, this antenna was right-
hand circularly polarized, following to the definitions in
standards of the day. Per modern definitions, the original
Model 3101 is left-hand circularly polarized (e.g. when
observed along the direction of propagation, the rotation of
the wave is counterclockwise, while the wave is left-hand
circularly polarized). By modern definitions, EMCO's optional
Model 3101L is right-hand circularly polarized. The current
model numbers remain unchanged for reasons of continuity,
but the description of their performance has changed to
reflect modern definitions.
