The short answer is Yes. No matter the type of splitter you choose, there will be an associated loss in signal. Most splitters distribute the signal equally amongst the output ports. A two-way splitter can reduce the signal strength by 3.5 dB. Similarly, three-way and four-way splitters have a maximum signal loss of 7 dB. As the number of output ports increases, so does the total loss in signal. You can combat this issue in a few ways. Firstly, you can install a distribution amplifier that amplifies the input signal before sending them to the output ports. In doing so, the output ports receive the same strength of the signal as the input signal. Another method is to add terminator caps. Terminator caps be attached to every unused port. While this does not stop signal leaking completely, there will be a reduction in the degradation. Also, use high-quality cables. Cheap cables can cause signal loss as well.
