Abstract : EFFORT IS PRESENTED ON THE INITIAL PHASES TO DEVELOP AN IMPROVED TRANSMISSION LINE SYSTEM FOR USE IN THE ECM MAST OF A SUBMARINE. AN IMPROVED COAXIAL-TO-DOUBLE RIDGED WAVEGUIDE ADAPTOR WAS DEVELOPED WHICH DISPLAYS A VSWR CHARACTERISTICS NOT EXCEEDING 1.3. CONCERN AT PRESENT ISWITH DEVELOPING AN IMPROVED SYSTEM SUITABLE FOR PRODUCTION, WITH EMPHASIS ON THE FOLLOWING FOUR AREAS: (1) FURTHER REDUCTION OF INSERTIONLOSS BY AT LEAST 1.0 DB AS A TARGET FIGURE; (2) REDUCTION IN WEIGHTWITHOUT IMPAIRING PERFORMANCE; (3) EASE OF INSTALLATION IN THE SUBMARINE; AND (4) TO INCORPORATE A PROVISION WHICH WILL PERMIT THE ANTENNA TO BE OPERATED IN EITHER OF TWO ELEVATED POSITIONS APPROXIMATELY FOUR FEET APART
