Quick Answer: Can Cable Splitters Go Bad?

Do cable splitters degrade signal?

A cable splitter WILL result in a degradation of the signal, even if the other ports are unused.

One thing you can do is to add terminator caps to each unused port.

They are supposed to reduce the degradation.

Note that cheaper cable splitters will actually have a different amount of signal loss for each port..

Is there a difference in cable splitters?

Is there a difference in the quality of coax splitters? Not all coax cable splitters are created equally. Low quality coax splitters can adversely affect the video signal, causing excessive attenuation of the signal (signal loss) and multiple reflections which can cause ghosting (shadows on the picture).

How many splitters can you put on a cable line?

Use a splitter with as few connections as possible (two way splitters will typically have the least signal loss). Try not to daisy chain splitters (splitter attached to a splitter). If you need more ports, a four-way splitter is better than 3 two-way splitters. I’ve seen splitters with as many as 16 ports.

Does length of coaxial cable affect signal?

When it comes to signal loss over longer cable lengths, the basic rule of thumb is that a 50-foot cable can experience noticeable signal loss, and a 100-foot cable can drop as much as one-third of the original signal.
