    I have a 4-way satellite splitter that I would like to convert to a 3-way spliiter. I assume if I am able to disconnect the 4th port the signal loss will be less. The red mark in the picture is where I plan to cut the circuit wire, but I am unsure about what to do with R3, C2, R4. Should I just leave them connected or should I desolder R3 to keep port 4 from receiving any signal. I am not sure what R3, C2, and R4 do. Are those components important for port 3? Thanks.

    Hello,

    The signal paths inside the splitter are well calculated.
    If you cut some of the path the result will be dissapointing.
    (possible goast images, due to reflections).
    The best way to "disconnect" port 4 is to put a resistor of 75 Ohms on it.
    There are special connectors with resistors build in for it.
