Why Should You Choose a High-Quality Coaxial Cable from the Start?
The coaxial cable is one of the most important components in any antenna or satellite installation. Although it is often considered a simple accessory, it actually has a direct impact on the quality and stability of the signal. For this reason, choosing a high-quality coaxial cable from the beginning is critical, as it is usually the only component of the installation that is not easily replaced once the installation is completed.
Unlike other devices, such as amplifiers or receivers, the cable is installed inside walls, conduits, or cable channels and remains there for many years. For this reason, professional installers should prefer reliable, high-quality cables that offer low signal loss and high protection against interference.
Coaxial Cable Is the Foundation of Every Installation
In every TV antenna or satellite installation, the coaxial cable is the main medium that carries the signal from the antenna or satellite dish to the receiver or television. All the equipment in the installation, such as amplifiers, multiswitches, and receivers, relies on the quality of the cabling to operate correctly.
Even the most advanced equipment cannot perform properly if the cable used has high signal loss or insufficient shielding. For this reason, the coaxial cable is considered the “backbone” of every installation, as the quality of the final signal largely depends on it.
Choosing a high-quality cable from the beginning can prevent issues such as signal loss, interference, and unstable reception. For this reason, professional installers prefer certified cables with high specifications, such as those manufactured by Kathrein, which are specifically designed for demanding RF installations.
The coaxial cable is the main signal transmission line in every antenna installation.
Why Is Coaxial Cable Not Easily Replaced After Installation?
In a typical antenna or satellite system installation, most components can be replaced relatively easily. An amplifier, a receiver, or even an LNB can be changed without much difficulty when an upgrade or repair is needed.
However, coaxial cable is a different case. During installation, the cable usually runs through:
- walls
- electrical conduits
- cable ducts or channels
- floors and technical shafts
In many cases, it is hidden inside the building structure, which makes its replacement particularly difficult and time-consuming. If signal problems appear after a few years due to low-quality cable, replacing it may require:
- opening walls
- installing new cabling
- reinstalling equipment
For this reason, choosing a high-quality coaxial cable from the beginning is considered an investment that ensures the long-term reliability of the installation.
Professional installers know that a high-quality cable significantly reduces the likelihood of future problems and ensures stable signal transmission for many years. This is why high-specification cables are often preferred, such as the professional cables manufactured by Kathrein, which are designed for durability, low signal loss, and high protection against interference.
| Installation Component | Can It Be Easily Replaced? |
|---|---|
| TV Receiver | ✔ Yes |
| Signal Amplifier | ✔ Yes |
| Satellite Dish LNB | ✔ Yes |
| Multiswitch | ✔ Yes |
| Coaxial Cable | ❌ Difficult |
Problems That a Low-Quality Coaxial Cable Can Cause
Using a low-quality coaxial cable can create several problems in an installation, which often appear after some time of operation. Although the system may initially function normally, the signal quality can significantly deteriorate over time.
The most common problems caused by poor-quality cables include:
- increased signal loss
- interference from external sources
- unstable channel reception
- pixelation or image interruptions
In many cases, the issue is not related to the equipment but to the cabling itself. A low-quality cable may have insufficient shielding or a low-purity conductor, which directly affects the quality of signal transmission.
It is also worth noting that the price difference between a low-cost, low-quality cable and a reliable professional cable is usually very small. For this reason, many installers prefer to choose high-quality cables from the start, such as those manufactured by Kathrein, which offer high performance and long service life.
In practice, the small difference in cost can save significant time and money in the future, as it reduces the likelihood of installation problems and the need for repeated maintenance or interventions.
| Feature | Low-Cost Cable | High-Quality Cable |
|---|---|---|
| Conductor | CCS | Pure Copper |
| Shielding | Low | High |
| Signal Loss | Higher | Lower |
| Durability Over Time | Limited | Long |
What Characteristics Should a High-Quality Coaxial Cable Have?
Choosing a high-quality coaxial cable is crucial for the performance and lifespan of an antenna or satellite system installation. A good cable not only ensures better signal transmission but also provides greater durability over time and resistance to external conditions.
When selecting a cable, there are several key characteristics that should be taken into account.
Pure Copper Conductor
The central conductor of the cable plays an important role in signal transmission. Cables with a pure copper conductor exhibit lower losses compared to cables that use CCS (Copper Clad Steel) conductors.
High-Quality Shielding
One of the most important features of a coaxial cable is its shielding. Shielding protects the signal from external interference and contributes to the stable transmission of television or satellite signals.
However, it is important to understand that the indication “high shielding” printed on a cable does not necessarily mean that it provides the same level of protection across all frequencies. In some cases, a cable may show good shielding at lower frequencies but lower effectiveness at the higher frequencies used in satellite signals.
For this reason, professional installers always examine the cable’s technical specifications and its performance across the frequency range used in the installation. A high-quality coaxial cable should maintain a high level of shielding throughout its operating spectrum.
Professional cables manufactured by Kathrein are designed to provide effective shielding even at high frequencies, ensuring stable performance in satellite and television installations.
Proper shielding protects the signal from interference that may come from:
- mobile communication networks
- electronic devices
- other sources of electromagnetic radiation
Low Signal Loss
A high-quality cable is designed to provide low attenuation, even at high frequencies, which is particularly important for satellite installations.
Resistance to Time and Environmental Conditions
The cable should have an outer jacket capable of withstanding:
- UV radiation
- humidity
- temperature variations
Professional coaxial cables manufactured by Kathrein meet high European standards and are designed to provide stable performance even in demanding installations.
For this reason, they are often used in professional projects, building installations, and television distribution systems where reliability is critical.
| Feature | Importance |
|---|---|
| Pure Copper Conductor | Better signal transmission |
| Strong Shielding | Protection from interference |
| Low Attenuation | Better image quality |
| Durable Outer Jacket | Longer service life |
