Can You Use a Splitter on a Digital Antenna?

Using a splitter with a digital antenna can be a convenient and cost-effective solution for distributing the antenna signal to multiple TVs or tuners within your home. By splitting the signal, you can enjoy over-the-air broadcast channels on multiple devices without the need for separate antennas for each TV. In this article, we will explore the use of splitters with digital antennas, the types of splitters available, and considerations for optimal signal distribution.

Types of Splitters

There are two main types of splitters: powered and passive. A powered splitter provides amplification to the TV signal, while a passive splitter acts as a straight passthrough without any amplification. Each type has its own advantages and use cases.

A powered splitter is recommended when you need to boost the signal to every tuner. This is particularly useful if your antenna is located far away from the TVs or if your house has poor electrical grounding. The amplification provided by the powered splitter helps overcome signal loss and ensures a strong and reliable signal to each connected device.

On the other hand, if you only need to amplify the signal to one tuner, you can use a passive splitter along with a standalone amplifier specifically for that output. This allows you to maintain a strong signal to the desired TV or tuner while keeping the other outputs unaffected by the amplification.

Signal Degradation and Insertion Loss

When using a splitter, it’s important to be aware of signal degradation, also known as insertion loss or attenuation. Insertion loss refers to the reduction in signal strength caused by the splitter. While using a passive splitter may introduce some degree of signal degradation, it is generally not significant and should not noticeably impact the picture and sound quality on your TVs.

However, it’s worth noting that using multiple passive splitters in a cascaded setup, where one splitter is connected to another, can result in cumulative insertion loss. This means that each additional splitter in the chain reduces the signal strength further. In such cases, it may be necessary to use powered splitters or consider alternative distribution methods to maintain optimal signal quality.

Placement and Usage

Powered splitters require proximity to an electrical outlet for power and may come with their own power cord. It’s essential to ensure proper placement of the powered splitter to ensure easy access to power. Additionally, consider the length of the coaxial cables connecting the splitter to the TVs or tuners. If the cable length exceeds 50 feet, signal loss may become more noticeable, and using an amplified splitter or booster can help mitigate this issue.

Splitters can also serve as combiners, allowing multiple signal wires to come in and one to go out. This functionality is particularly useful when wiring multiple rooms inside your walls or attic, allowing you to distribute the antenna signal to different locations efficiently.

Signal Issues and Troubleshooting

In some cases, adding a splitter may introduce signal issues, such as pixelation or weak reception. If you encounter such problems, using a filter as a troubleshooting step can help reduce electrical noise and interference, improving the overall signal quality.

Important Considerations

It is crucial to note that splitters are designed specifically for television signals and should not be used for internet signals. If you have coaxial cables in your setup that are also used for internet connections, it is recommended to consult your internet service provider before making any changes to the coaxial cable configuration.

FAQs

Can I split the signal from a digital antenna and connect it to multiple TVs?



Yes, using a splitter with a digital antenna allows you to split the signal and send it to multiple TVs or tuners within your home.

What are the types of splitters available for digital antennas?

There are two types of splitters: powered and passive. A powered splitter provides amplification to the TV signal, while a passive splitter is a straight passthrough without any amplification.

When should I use a powered splitter with my digital antenna?

A powered splitter is recommended when you need to boost the signal to every tuner. This is useful if your antenna is far from the TVs or if your house has poor electrical grounding.

Can I use a passive splitter if I only need to amplify the signal to one tuner?

Yes, if you only need to amplify the signal to one tuner, you can use a passive splitter with a standalone amplifier on that specific output. This allows you to maintain a strong signal to the desired TV or tuner while keeping the other outputs unaffected by the amplification.

Does using a passive splitter cause signal degradation?



Using a passive splitter may cause some signal degradation, known as insertion loss or attenuation. However, the degradation is usually not significant and should not noticeably impact the picture and sound quality on your TVs.

Can I use multiple splitters in a cascaded setup?

It is possible to use a splitter to feed another splitter. However, each passive splitter adds more insertion loss, and multiple powered splitters can cause overmodulation, potentially impacting the signal quality.

Where should I place a powered splitter?

Powered splitters need to be located near an electrical outlet as they require power to function. Ensure proper placement to facilitate easy access to power.

Can splitters also function as combiners?

Yes, splitters can also function as combiners, allowing multiple signal wires to come in and one to go out. This can be useful for wiring multiple rooms inside your walls or attic, enabling efficient distribution of the antenna signal.
