Helicopter Communications Via UHF Satellite Relays.

Abstract

Tests to determine UHF teletype performance and antenna patterns on a UH-1F helicopter were conducted in an in-house program to study helicopter communications via satellite relay. Four configurations of special antenna designs were fabricated and tested in an effort to improve communications reliability by reducing the detrimental effects of the rotor blades shadowing the antennas intermittently during operational performance. These tests were conducted using the LES-6 and TACSAT-1 satellites with a cooperating airborne terminal, Air Force C-135 aircraft, No. 662, W-PAFB, and ground-based terminals at Wright-Patterson AFB, Ohio, and Electronic Communications, Inc. (EC1), St. Petersburg, Florida. (Author)
