How to Connect Outdoor Antenna to Multiple TV?

Updated On June 29, 2021

Using an outdoor antenna allows you to pick up a large number of TV signals. To take advantage of this piece of technology, we develop a simple list of steps to be performed. It is possible to connect an outdoor antenna to multiple TVs without additional accessories.

Before you proceed, here's the TV outdoor antenna best guide that you can check.

It should be noted that there is a big difference between an indoor antenna and an outdoor antenna. Those who live in the city can rely on an indoor antenna to pick up many signals. An outdoor antenna is a more suitable option to pick up signals at a greater distance.

It is recommended to install an outdoor antenna on the highest part of the home. This will allow all types of signals to be picked up more efficiently while avoiding many obstacles. The type of outdoor antenna should also be considered.

There are directional and omnidirectional outdoor antennas. Those users with an external directional antenna will have to orient their antenna towards the site where the signal transmitter is located. This antenna can pick up signals over a greater distance, although only a few signal transmitters should be chosen.

External omnidirectional antennas do not need to be pointed at a specific location. These antennas have the characteristics of successfully picking up signals in 360 degrees. They only need to be installed at the top of the home to be operational. All the necessary accessories to properly install the antenna are also usually incorporated.

2. Incorporating an RF Coaxial Splitter 

It is highly recommended to incorporate a coaxial splitter once the user has done the front installation. This is a critical piece of technology, and that all TV sets can have an antenna signal. Every TV set in the home will be able to enjoy the different local channels available.

On some occasions, you may notice a drop in signal strength by 3.5 dB or 50% of the signal obtained. The overall strength of all signals received by the antenna also decreases as additional splitting is incorporated. This negative aspect should be considered when splitting the signal into different TV sets.

This negative aspect is not as important when the signal obtained is strong enough. The splitter needed for the number of TV sets in the home should also be considered. The signal strength will be weaker on a four-way splitter compared to a 2-way splitter.

Despite the unused outputs, the signal strength is weakened anyway. Even the signal is also weakened concerning the distance to be traveled. A stronger signal can be obtained as the coaxial cable has less length. All this will result in high picture quality. 

Even signal loss may not be noticed in the same way on different televisions. This is especially noticeable when using a three-way splitter. One TV might offer pictures with weak signals while the other two might provide strong signals.

3. Connecting the Main TV Set and the Second TV Set

It is highly recommended to perform and complete the installation of a single TV before moving on to the next TV. This will make it much easier to detect any problems connected from the coaxial splitter to the TV. It is recommended to choose the main TV set as the closest TV set to the coaxial splitter.

It will be possible to analyze the quality of the signal that the closest TV will get. If you do not get an excellent signal quality, you can check each connection from the outside antenna to the TV. Once a sufficiently strong signal is obtained, it is possible to move to the second TV set.

It is only necessary to perform the same procedure when connecting the second TV to the coaxial splitter using a coaxial cable. This exact procedure can be repeated, taking into account the number of TV sets needed for the household.

The smaller the number of TV sets, the smaller the number of times the received signal can be divided. This is always positive for a strong signal and quality images.

4. Add a Coaxial Amplifier

The signal can weaken too much from the third or fourth television. It is possible to incorporate a coaxial amplifier, but it is necessary to check the results before incorporating this device. It is often not needed to install a coaxial amplifier. Some people prefer to install an outdoor antenna with a long-range. (1)

Not only can it be useless, but it can also produce a signal overload. An overload signal could affect some of the parts of the connections or the televisions themselves. It should be taken into consideration that there are two main types of amplifiers.

  • Preamplifiers: This device allows to improve and amplify the signal received in the downstream cable of the antenna. This amplifier should only be installed on the original antenna cable and not anywhere else. Some amplifiers even have the versatility of being useful for an outdoor or indoor antenna.
  • Distribution Amplifiers: This device allows maintaining the original signal strength and distributing this same signal to multiple TV outputs. It is an excellent choice when the weakness of the signals is too much, and some TV sets only offer bad images.

Final Words

It is not always necessary to incorporate too many accessories, such as an amplifier. Today, there is a wide variety of outdoor antennas that offer an extraordinary range. The key is in the installation procedure of the antenna itself.

It may be highly advisable to modify the site chosen for the outdoor antenna installation. This may improve the received signal for multiple televisions. Even this same procedure may require some patience but could avoid unnecessary amplifier expenses.

Here are some learning guides which you can check later on, first, here's how to make an outdoor TV antenna, and how to ground an outdoor TV antenna. Until next time!
