(54) High frequency attenuation cable and harness


(57) A high frequency attenuation cable comprises a core comprising at least one conductor, each conductor being surrounded by a high frequency absorption medium and at least one layer of high dielectric constant material having a dielectric constant (ε) greater than about 4 when measured at 10 MHz and a volume resistivity of at least about 10'3 ohm-cm. The high dielectric constant material may be positioned between the conductor and the high frequency absorption medium, outside of the high frequency absorption medium or both. The high dielectric constant material is preferably polyvinylidene fluoride. There is also disclosed a high frequency attenuation harness which includes a plurality of such high frequency attenuation cables.
