Abstract
Abstract A water migration proof radio frequency transmission system and method is disclosed. The system comprises an unpressurized foam dielectric coaxial cable having a center conductor surrounded by a foam dielectric which is surrounded by an outer conductor. The system also comprises a connector for connecting the center and outer conductors of the cable to the center and outer conductors of an antenna. The connector includes sealing means for preventing moisture migration into the cable from the center conductor of the antenna. In one embodiment the connector has an insulative center conductor contact bead with an O-ring positioned on its outer periphery and with a bore in the bead press fit to an inner conductor contact which in turn connects to the coaxial cable center conductor. In another embodiment the bead includes a second O-ring within the bore for moisture sealing engagement with the inner conductor. The method uses such a connector within a dielectric foam coaxial cable to form a moisture proof radio frequency transmission system.
