There are also splitters available with more output options. You can use 2-way, 3-way, 4-way, 6-way, or 8-way cable splitter as per your needs. That means you have to provide an input through a single coaxial cable to the splitter and you can get as many output signals as you want.
Using a cable splitter, one can get the cable signal on more than one television just by using the one signal.
