Semaphore is sent using two square flags. Each side of the flag is 18 inches. The length of the flag staffs are 24 inches. The flag is divided diagonaly in the middle with two colors, red and white. The red color is attached to the staff and the white color is below it. When sending semaphore, keep your arms straight and move directly to the position of each letter. For the most part, each sequential letter moves clockwise. We can divide up the letters into 7 circles (see below). When sending numbers, we send a numeral signal and use the letters A through J for the numeral 1 through 0.
