Abstract: A cable television apparatus improving high frequency characteristics includes a first connector and a first choke. The first connector is electrically connected to an input coaxial cable or an output coaxial cable. The first choke is electrically connected to the first connector. The first connector includes a first signal transmission unit. The first choke is used to block a cable television signal. The first choke allows a first current flowing through the first choke. The first current is greater than or equal to 10 amperes. The first choke is directly touched the first signal transmission unit, or a connection path length between the first signal transmission unit and a pin of the first choke is less than 5 millimeters.

Abstract: A signal splitting device is to be installed in a CATV passive apparatus. The signal splitting device includes a circuit board that is disposed in a cover of the CATV passive apparatus, and a first connecting terminal and a second connecting terminal that are mounted to the circuit board and that are connected respectively to input and output terminals of the CATV passive apparatus. Each of the first and second connecting terminals includes a pin electrically connecting the circuit board and the corresponding one of the input and output terminals. The pin has a segment that is between the circuit board and the corresponding one of the input and output terminals and that has a length ranging from 4 to 15 mm.

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.

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.
