As the name implies, a coax signal splitter takes the power on the input port and splits it equally among the output ports. For example, a 2-way splitter has one input port and two output ports. It sends half the power of the input signal to one of the output ports. The other half is sent to the other output port.
Do cable splitters weaken signal?
A splitter is a device used to split a cable signal between two or more devices. A splitter weakens the signal level, which can cause intermittent loss of service or, in rare cases, service failure.
Does a coax splitter work both ways?
Reverse a splitter to combine signals from different antennas. Splitters contain no electronic devices and don’t require any power, making them “passive” instead of “active.” Because of this, they can be connected in reverse without any damage.
Does using a coax splitter reduce quality?
Any time a TV signal is split, it will encounter insertion loss that will weaken the signals distributed beyond the splitter. If you experience signal issues while using a splitter, you may need to install a distribution amplifier or a preamplifier.
