1200 FREQUENCY MODULATION, Volume-A single section, Figure 1, weighs only 350 lbs., or 700 lbs., for twosection, while a 4-section assembly, made of heavier material, comesto 2,000 lbs. These weights include, the radiators, transmission line,beacon, steps, and hardware.The ice problem is negligible because the transmission lines areinside the cylinders, where ice formation is unlikely.Any formation onthe outside will add little to the weight and loading. Maintenance ismade easy by the simple feed-line arrangement, the small number ofend seals, and by the fact that the lines are enclosed within theantenna sections.aIit)
