LOW-FREQUENCY AIRBORNE ANTENNA SYSTEM.

Abstract

Efforts concern a study program to determine the optimum design and the fabrication requirements for a Low Frequency Airborne Antenna System. The System will be capable of operating in the frequency range from 30 to 300 kcs and will be used with airborne communication and navigational receiving equipments on a multiple or time-sharing basis. Various antenna systems were analyzed and evaluated in terms of specific design goals for a low-frequency navigationcommunication receiving antenna system for use on several types of U.S. Army aircraft, both fixed-wing and rotary. In addition to the design goals, the antenna systems were considered in relation to three specific factors--susceptibility to electrical noise environment, antenna polarization, and sensitivity. The effects of helicopter rotor-modulation on the antennas were studied. The preliminary engineering design of an airborne, omni-directional, 30-300 kc whip antenna fith preamplifier, designed to obtain optimum electrical and aerodynamic performance, was completed.
