AbstractA problem arose regarding the transmission from a commercial beacon antenna, the AT-781/U, in that an abnormal drop in signal level was observed over a certain region in azimuth. After testing, the antenna turnstile was matched and phased for the operating frequency. New turnstile elements were required. Patters of the original and modified antenna were taken.
