AN IMPROVED BROADBAND LOW LOSS TRANSMISSION LINE SYSTEM TO BE INSTALLED WITHIN A RETRACTABLE SUBMARINE MAST
Abstract
Efforts were continued on the development of an improved transmission system for use in a submarine mast. The ALB-134 ridged waveguide and the optimum size Splinaline coaxial cable were received. A 1-in.-radius 90 degree coaxial bend was fabricated and tested. This bend, in conjunction with a 90 degree coax-to-ridge wave guide adapter, will form the end-fired configuration needed at the top of the mast. The design of the coupling plate and rail assembly needed for a continuously operating system over a 6 foot range was completed and parts were fabricated. The design of the pressure windows was completed. A 50 ohm model, which will be used for both bands, was built, electrically tested and certified at 7000 PSI. A graph of VSWR versus frequency is shown. The 50 to 70 ohm transition was designed. An improved 50 ohm flexible cable was located which can reduce the loss in the line by 50%.
