Abstract: A cable television apparatus is applied to an input coaxial cable and an output coaxial cable to transmit a cable television signal and an alternating current power. The cable television apparatus includes a high saturation current transformer, an input terminal, an output terminal and a coupling side. The high saturation current transformer includes a ferrite core, a primary side circuit and a secondary side coil. The ferrite core is a high saturation current ferrite core, so that the primary side circuit transmits the cable television signal and the alternating current power, and couples the cable television signal to the secondary side coil.

Abstract: A video splitter includes a housing. The housing has a seat shell and a cover shell. A pair of main signal ports is provided in the seat shell. At least part of the main signal ports is out of contact with the seat shell. A pair of pushing rods is provided in the housing. The seat shell has an insulative element, a pair of elastic beam terminals and a conductive element. The conductive element connects with the elastic beam terminals. Each of the elastic beam terminals is separately and movably arranged between one of the main signal ports and the seat shell. The seat shell has ferrite elements. A splitter board is disposed in the cover shell. The splitter board has a pair of first terminals correspondingly connecting with second terminals in the main signal ports. Splitting signal ports electrically connecting with the splitter board are provided outside the cover shell.

Abstract: A cable television apparatus is applied to an input coaxial cable and an output coaxial cable. The input coaxial cable and the output coaxial cable transmit a cable television signal. The cable television apparatus includes an input side, an output side, a directional coupler and a compensation antenna. The directional coupler includes a coupler input side, a coupler output side, a coupler matching side and a coupler coupling side. The compensation antenna is electrically connected to the coupler matching side of the directional coupler or the coupler coupling side of the directional coupler. The directional coupler utilizes the compensation antenna to wirelessly send out a coupler signal or receive a high frequency wireless cable television signal to proceed a signal compensation.

Abstract: A cable television apparatus is applied to an input coaxial cable and an output coaxial cable to transmit a cable television signal. The cable television apparatus includes an improved choke, an input side, an output side, an input capacitor and an output capacitor. The improved choke is electrically connected to the input coaxial cable, the output coaxial cable, the input side, the output side, the input capacitor and the output capacitor. The improved choke includes a conductive wire and a ferrite core. One side of the conductive wire is electrically connected to the input side and one side of the input capacitor. The other side of the conductive wire is electrically connected to the output side and one side of the output capacitor. The ferrite core covers one part of the conductive wire. Moreover, the ferrite core is a high saturation current ferrite core.
