Common Causes of Poor TV Reception in Your Home

We have all experienced poor TV reception at some point in our lives, and it is an incredibly frustrating thing. In contrast to the old analog TVs, digital televisions rely largely on data and reception to produce good-quality pictures on the screen. The problem with data and reception is that they can sometimes be distorted or weakened. Whilst poor reception is a common problem for many people, the issue is often easily solved. 

If you are currently suffering from poor TV reception, read on and find out ways to fix the common causes of TV reception problems.  

1. Weak Signal

Nowadays, digital TVs offer us higher quality pictures and better clarity compared to the analog TVs of the past. However, your picture-perfect digital TV might quickly become a source of frustration when the pictures appear snowy, distorted, and grainy on screen due to weak TV signals. When your TV signal is weak, it is common for both your audio and video to have issues and then eventually cut out altogether. Weak signals on TVs can be caused by various reasons, including having obstructions such as trees or tall buildings between your home and the signal transmitter or even living in a hilly area. 

Having a weak signal is a common problem for many homeowners and getting a signal amplifier for your TV is one of the easiest ways to fix it. The experts from explain that if you live in an area that has weak television coverage, having an amplifier can improve your TV signal significantly and, in turn, give you access to high-quality entertainment with high-definition pictures. Getting a signal amplifier for your TV can also help you get rid of complicated cables as well. Depending on your personal preferences, you have a number of amplifier choices to choose from with differences in setup and price range.  

Incoming Signals that Are Too Strong

People often complain that they have TV problems associated with weak reception, however, receiving signals that are too strong can be a problem as well. Normally, TVs and other equipment have a maximum strength of signal which they can handle. For instance, in a residential environment such as your home, the signal you receive should not be more than 77dB. 

Thankfully, having signals which are too strong is a problem that can easily be fixed. You can try to remove unnecessary sources of signals such as amplifiers to eliminate potential causes of this over-loading problem. Before you start removing amplifiers and other devices, it is highly recommended that you check a transmitter map to see how close your TV is to the transmitter. Furthermore, replacing amplifiers with passive splitters or installing attenuators can help to drop your signal down as well. 

Local Interferences

Other than signal-related problems, problems related to local factors such as 4G and 5G interference, neighboring transmitters, co-channel interference, and interference from other forms of communication are common as well. This might seem surprising, but TV reception can be affected by something as simple as LED lights or electrical devices being used nearby. 

Depending on the interference problem you are having, you can purchase a 4G filter to filter out 4G signals or install a bandpass filter or notch filter to filter out interference caused by neighboring transmitters. Aside from common problems caused by 4G and neighboring transmitters, Tetra inference and co-channel interference are much less common. If you have a co-channel interference problem, you can choose to realign your TV to another transmitter. Fortunately, other communication methods that use high frequencies, such as 395Mhz, are not commonly used as much as before. 

Recent Changes to your TV Setup

One of the most frustrating things is if you suddenly start having reception problems when previously, there were none. If you are having problems with your TV out of nowhere and right after a change in TV setup, check whether the new distance between your TV’s reception point and the antenna is too far and whether your external antenna has recently been adjusted or not. 

Having TV signals that are either too weak or too strong can cause problems for your home TV. Sometimes, it is difficult to correctly identify which type of problem it is that you are having. Trying to determine the physical distance between your home and the transmission towers of the local TV station, as well as looking out for physical obstructions such as mountain ranges or tall buildings and tall trees, can help. However, there are many factors that can prevent you from being perfectly entertained with your home TV system. Therefore, sometimes you will have to contact a professional to conduct a site inspection or a system check if the problems remain unsolved.
