This report presents the results of work accomplished to investigate the feasibility of using the horizontal stabilizer of the CH-53A as an HF antenna. Ground tests were conducted to establish the ability of the horizontal stabilizer to provide an improved HF communications system for the CH-53A helicopter; the present fixed wire antenna was used as basis for the comparison. Results indicate that performance of the HF communication system with an isolated stabilizer antenna provides an improved communications capability for the CH-53A helicopter.
