What common device is used by an installer during the installation of an additional TV outlet and is found inside the VCR?

The use of a two-way splitter is essential during the installation of an additional TV outlet. A two-way splitter allows a single incoming coaxial cable signal to be divided into two separate signals, enabling multiple devices, such as TVs, to receive the same signal. When an installer is setting up an additional TV outlet, the splitter is used to share the cable signal from one source, ensuring that both outlets have access to the same programming.

While options such as a single-pole switch or a coaxial adapter might play roles in other installations, they do not perform the same function as a two-way splitter in providing signal distribution in this scenario. A multichannel receiver is more complex and not typically found within a VCR, thus not relevant to the context of simply installing an additional outlet using standard equipment. The splitter is a straightforward and practical device specifically designed for this type of installation.
