This report covers the design, development, construction, and testing of a directional glide-slope antenna system that is compatible with standard airborne receiving equipment. The design effort resulted in an array of thirty dipole radiators which are fed in such phases and amplitudes as to produce an on-course signal on a plane perpendicular to and bisecting the axis of the array. The array is designed to radiate minimum energy in the sector from three to nine degrees below path, in order to minimize the effects of the terrain in front of the antenna upon the path shape. The array of dipoles is mounted on a 72-foot tower whose angle with respect to vertical is adjustable between 2.5 and 3.3 degrees, thereby permitting the glide slope to be adjusted through the same angle. The antenna was installed at ITT Federal Laboratories facilities in Lincoln Park, New Jersey, and preliminary flight tests were made at this location. Author
