Aerial splitters will weaken your signal. However in reasonable signal strength areas your TV can cope with this loss OK, particularly if only splitting the signal twice. Thus, unless you live in a known poor signal area, we recommend trying a splitter before you try an amplifier / booster.

Does a splitter affect signal strength?

A splitter will have approximately 3.5 dB of loss on each port. TV signal splitters with more than two output ports are normally made up of multiple two-way splitters. In terms of dB loss, there will be approximately 7 dB of signal loss on each output port.

Do 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.

Do coaxial splitters affect speed?

Cable splitter only reduces signal strength. It wont affect the internet speed.

Do aerial splitters fail?

Can a Splitter Go Bad? Yes, over time, splitters tend to degrade and that may result in signal loss. While you cant avoid this completely, you can slow the process down by using terminator caps on the unused ports.

Can coaxial cable be too long?

It is recommended that you use as little coaxial cable as you can. Using too much coaxial cable can result in as much as a 1/3 of the signal being lost. Also do not coil the coaxial cable as this can cause signal loss. Instead let the cord lay uncoiled if possible.

How do I choose a coaxial cable splitter?

The three things to consider when choosing a coaxial splitter to split your antenna signal are frequency, attenuation (or dB loss), and the number of outputs.

How do you fix a weak cable signal?

How to Improve Cable TV Signal StrengthCable box. Cordless phones can disrupt cable signals. Remove any unneeded cable splitters. Check all cable lines in the home for damage. Use a cable signal meter device and check the signal coming into your house, and check all the wiring in your residence.

Can the length of a coaxial cable affect signal?

The difference of signal losses over coax cable length can be very problematic in large TV systems and long cable runs as you have to consider signal losses at different frequencies on the same cable. Over distance this can cause the higher frequency signals to become weaker in relation to the lower frequency signals.
