Abstract
Abstract In accordance with the teachings of the present invention apparatus for permitting interference free transmission of high frequency signals in any given frequency range is provided. In the inventive apparatus, a central conductor of a coaxially disposed pair of conductors is employed to radiate high frequency signal information and the coaxially disposed pair of conductors is mounted in a parallel manner to the path of a tracked vehicle on a support. The support includes a metallic member disposed along the entire length of the coaxially disposed pair of conductors which is periodically connected to the outer conductor of the coaxially disposed pair of conductors to substantially reduce field strength fluctuations through a suppression of induced secondary waves in the immediate proximity of said central conductor.
