Typically used in your tv or cable modem. Screws on.
Splits cable signal into two cables.
Splice two shorter sections of cable together to make one longer section.
Primarily used for cable tv. Ohm rating: 75
More robust. Primarily in used today for data transmission. Ohm rating: 75
Ohm rating. Used to describe impedance and wire's capacitance.
