How to improve the reception of your indoor antenna
Most of the people who have indoor television antennas deal with weak reception. It is quite frustrating to live with a weak television reception as well. That’s because you will not be able to enjoy the television channels that you are interested in watching. If you are struggling with this issue, there are few effective tips, which you can follow in order to improve the reception of the indoor antenna.
The television signals are coming to your place with a finite amount of power. It is possible for you to define this amount of power through noise margin. Usually, the noise margin is given through decibels. In fact, it refers to the amount of signal, which can be received without any issue.
If the noise margin is above 0, the television tuner will be able to capture it and display on the television. However, noise will exist in the line, which connects the TV tuner and the antenna as well. In fact, this noise is within the signal splitters, coaxial cable and the tuner that receives the signal.
Any component that is located in between the receiver and antenna has the ability to give life to noise. If the noise is too much, it would give life to a negative noise margin. Hence, you will not be able to get any reception on your television.
With that in mind, let’s take a look at some steps that you can take in order to improve the reception of your indoor antenna.
Position the indoor antenna correctly
By positioning the indoor antenna correctly, you will be able to improve the reception. You need to understand the direction, where signal is generated. Then you need to understand whether the channels provide a positive noise margin to your location.
It is possible for you to use a signal analysis tool, such as TVFool.com in order to get to know about the direction and the noise margin of a specific television broadcast at your location.

You will then be able to use a compass and align the direction of your television antenna accordingly. If you don’t have a compass, you don’t need to worry about anything as it is possible to get it as a smartphone app.
Get a uni-directional antenna
If all the signals are coming from the same direction, it is worth to invest your money in purchasing a uni-directional antenna. The uni-directional antennas are more effective in capturing signals that are coming from one direction, when compared to omni-directional antennas.
The biggest benefit that you will be able to get from a uni-directional antenna is the gain. Gain is also calculated in decibels. It is added into the noise margin. Hence, the loss of signals due to noise can be minimized with gain.
Be mindful about obstruction
The obstructions in your neighborhood, such as buildings and trees are in a position to obstruct the signals that you receive. Usually, the transmission towers are tall and they are in a position to ignore most of the trees and buildings. However, a building or a tree that is located closer to your home will be in a position to obstruct the signal.
You can simply do a test and determine if a building or a tree is obstructing the signals that you get. You need to go near the antenna and see if you can look up at an angle of 45 degrees, without being obstructed by the tree or building. Then your antenna will be in a position to capture the transmission signals in an effective manner.
You should also keep in mind that trees are one of the biggest contributors towards noise. As per the statistical records, trees can create a loss of UHF signals by around 10 to 14dB. Depending on the type of tree you have, it can be 18.4dB. It is better if you can calculate all obstacles in your neighborhood to arrive at a value that indicates the noise margin. Usually, every obstacle will reduce the signals by around 10dB. Therefore, you need to calculate the signal loss by all obstacles in the neighborhood and check if you can arrive at a noise margin of at least 35dB. Then you will be able to get an uninterrupted experience when you watch television.
Get rid of noise in the line
The line that is being used to connect your antenna and television will also induce a lot of noise. You need to think about getting rid of this noise as well. Otherwise, it will not be possible for you to get a better experience out of the indoor antenna that you have.
You need to replace the existing coaxial cable with a more efficient one. You can also enhance the knowledge that you have on coaxial attenuation. Then you will be able to get a better understanding on how to select a better coaxial cable. The splitters and TV tuner can also cause noise. Usually, one splitter can cause a signal loss that is equivalent to 3.5dB. The tuner will also cause a loss of 1dB.
When installing a new antenna, an amplifier or a booster is being used. This amplifier can add gain into the signal. Hence, the noise will be compensated. However, you should also keep in mind that a booster is not in a position to increase the noise margin, than the amount that it receives by the television antenna.
Should you use an amplifier at all times?
You don’t need to use an amplifier at all times. For example, if you are getting the signal from the broadcast station with a noise margin of at least 30dB, you don’t need to worry about the signal quality. You will be able to enjoy television without using a booster.
Just follow these simple steps and you will be able to make sure that you get the best signal reception from the indoor antenna that you have at your home.
