Why is my Antenna not Picking Up Channels?

Updated On July 12, 2021

Do you want to enjoy your channels, but your antenna has reception problems? Can't figure out exactly where the problem is? There are some widespread problems, such as signal interference or specific issues with your home connection. If you are wondering, "why is my antenna not picking up channels?" next is the answer.

1. Digital Tuner Problems

It is possible to start with one of the less frequent problems, and that is when the tuner may present some faults. A faulty digital tuner does not usually affect the TV set directly. A digital tuner might have a manufacturing failure even though it is brand new.

To check if the digital tuner is defective here's how to install an outdoor TV antenna. The connection to the coaxial cable to another TV set is also recommended.. This is one of the most efficient and quickest ways to detect if the problem is somewhere related to your main TV.

2. Lack of Antenna Range to the Transmission Tower

The vast majority of antennas have a specific effective range that is usually limited to 70 miles of range. This is not due to a lack of technology in the receiving antennas. It is due to the curvature of the Earth that prevents the antennas from efficiently receiving the signal. To fix this, here's how to boost an outdoor TV antenna signal. (1)

Many websites allow you to find out the location of all transmission towers near the area you are in. This is the best way to check if your antenna has sufficient capacity and the transmission tower is within 70 miles. Suppose the distance is more significant than that you will need special equipment and the right weather conditions.

3. Incorrect Coaxial Cable

A person may not have the necessary equipment to be able to receive a signal properly. Such inconvenience can be found in the coaxial cable. As this cable gets longer and longer, the signal loss is also higher and higher. (2)

30% of the signal can easily be lost when the coaxial cable is longer than 100 feet. Sometimes it is not possible to incorporate a shorter cable due to the structure of each home. It is possible to include an amplifier or preamplifier. Each TV should be tested to see where to incorporate this component.

The signal loss also occurs frequently when a signal splitter is incorporated. This device is specifically responsible for dividing the signal received by the antenna between the different TV sets. As more and more TVs are added, the signal for each TV is lost.

It could also happen that some of the parts from the antenna to the TV set are damaged. This could occur with damage to the outer antenna surface or some level of corruption in the coaxial cable. Checking all these aspects also allows you to check if the connections are made correctly.

4. Different Causes of Interference

signal interference
Among the most common causes may be the reasons for interference between a home antenna and the transmission tower. Within 70 miles, there could be special geographical features such as hills or a large number of trees. 

Buildings are also another reason why the signal could be lost from the transmission tower to the antenna. The most effective solution is to install the home antenna in the highest possible place. This optimizes signal reception and makes it easier to avoid any obstacles that might be in the way.

Harmful weather conditions could also be a problem when it comes to signal reception. This is somewhat similar to the interference that a 4G or 5G cellular network can produce. For this situation, special equipment is also available to avoid such interference.

Conclusion

There are several reasons why an antenna may not receive the channels properly. Knowing the functionality of the antenna allows one to know precisely where the problem could be.

Sometimes the reasons mentioned above may not be the ones that apply to each person. It is an excellent way to start looking for the solution. If you have any doubts, you can leave your comment below.
