Abstract:

An Ultra High Frequency Tail Cap Antenna, which was fabricated from Lockheed Aircraft Corporation drawings, was flush mounted on the tip of the vertical stabilizer of an F-94A aircraft and was subjected to flight tests as outlined in Military Specification MIL-A-6224. The antenna was tested on various UHF frequencies for range, audio quality, and signal strength, both air-to-air and air-to-ground. The tests revealed that although some areas of low signal strength were found forward of the nose of the aircraft, the antenna provided satisfactory communications, both air-to-air and air-to-ground. Communications were audible to a maximum range of 240 miles. The radio-frequency input signal strength to the antenna was greater than the three-microvolt minimum at all elevation angles which were greater than 1.2 degrees.
