Systems and related methods for reducing passive intermodulation (PIM) include a combination of an antenna control unit (ACU) and a remote electrical tilt (RET) system. The ACU may be used to generate rotational motion of an output drive shaft in response to an input tilt control signal. The RET system couples to the output drive shaft of the ACU and may be used to convert the rotational motion into translational motion for modifying a phase shift of an antenna beam. PIM may be substantially eliminated by providing electrical isolation between the ACU and RET system in the form of a non-conductive connector that engages the draft shaft of the ACU.

A kit and its preparing method concerning dual-antigen sandwich method are used for detecting the antibody against HCV, and its detecting mode is 'carrier-first antigen-antibody against HCV to be detected-second antigen-marker-distinguishable signal'. The kit ant its preparing method characterize in that the second antigen is the complex of a HCV and a tag.
