Abstract : The PHM is a high-speed patrol craft under development for possible NATO use. Small size, along with extensive weapon and communications requirements, complicates the problems of antenna selection and location. This document presents the results of an NELC study to provide two hf antennas (1) with maximum possible isolation between them, (2) with reasonable antenna system efficiency, and (3) so arranged that they meet the HERO requirement for the PHM weapons. NELC recommends that a fan antenna be installed for one hf transceive circuit and a 5.33-meter whip for the other. A second whip is recommended for backup. Impedance, pattern, and isolation data are presented. (Author)
