This was the wig-wag system which used the code invented by Albert J. Myer. Some of the towers used were enormous, up to 130 feet, to get a good range. Myer's code required only one flag using a ternary code. That is, each code element consisted of one of three distinct flag positions.
Albert James Myer (September 20, 1828 – August 24, 1880) was a surgeon and United States Army general. He is known as the father of the U.S. Army Signal Corps, as its first chief signal officer just prior to the American Civil War, the inventor of wig-wag signaling (or aerial telegraphy), and also as the father of the U.S. Weather Bureau.
The US Army Manual of Signals lists several alternative codes, including a three-element fixed-length code using four symbols (1866 edition), and a three-element fixed-length code using three symbols (1872 edition). There is no indication in the manual that these codes were actually in use. [10] Available colors for wigwag flags
