Abstract
An optimized coaxial transmission line having joined segments of coaxial transmission lines is provided. First insulating supports positioned at flange joints within the joined segments are provided. Second insulating supports are positioned a distance x, wherefrom the first insulating supports to cancel reflections created by the insulating supports. Preferably, x=¼λ, and the second insulating supports are positioned for one quarter of a wavelength at either FM frequencies, VHF frequencies, UHF frequencies, or IBOC frequencies. A method for optimizing a transmission line by frequency is also provided. First, segments of coaxial transmission lines are joined together, each segment having a first insulating support positioned at a flange joints within the joined segment. Next, a second insulating support is positioned along the length of each segment of coaxial transmission line a distance x from said first insulating support, where
