A cable TV's signal must be decrypted inside a cable box before it can be viewed on a television set. You can use wireless routing video transmitters to route the same signal from the cable box to 10 independent televisions by using wireless receivers. A splitter box will be needed to augment the TV signal, but otherwise no special tools are necessary. The transmitter and receiver routing devices and the splitter box can be purchased at computer or electronic stores and do not require any expertise in electronics to be used.
Screw an end of a coaxial cable into the coax output on the cable box. Screw the other end into the coax input on the splitter box. Plug the splitter box's power cord into a wall socket for power.
Insert an end of a HDMI video cable into each of the five HDMI video outputs on the splitter box. Insert the other end of the HDMI cables into the HDMI video input on each of the five wireless video transmitters.
Plug an outlet extender into a wall socket. Plug the power cords of each of the transmitters into an AC socket on the outlet extender. Press the "Source" button on each of the transmitters until the LED lights up next to the "HDMI" text.
Slide the frequency selector switch on each of the transmitters to one of five frequencies; for example, setting "1" or setting "2" and so on until you reach setting "5."
Place the 10 wireless video receivers next to the 10 television sets. Connect an end of a HDMI cable to the HDMI output on each of the receivers. Connect the other end of the HDMI cables to an HDMI input on each of the TVs.
Plug the power cords of each of the receivers into an AC socket for power. Press the "Source" button on each of the receivers until the LED lights up next to the "HDMI" text.
Slide the frequency selector switch on two of the receivers to the "1" setting, set another two to the "2" setting and so on until all 10 receivers are set to a frequency.
The signals from a wireless home network can interfere with the wireless video transmitters.
