Abstract: This article studies the working theory and structure character of antenna pedestal. Because of the zenith tracking blind zone, A-E style antenna pedestal could not satisfy the tracking demand. X-Y style antenna pedestal moves the blind zone to the two sides of Xaxis (the horizon), therefore satisfying the tracking demand. According to the project applications, several different configurations of X-Y style pedestals are proposed, including their specifications and applicability. The design in this article is project-oriented, therefore its results have important guidance meaning for the design of X-Y style pedestals.
