In the realm of technology, coaxial cables are a fundamental component, playing a pivotal role in the transmission of high-frequency electrical signals with minimal interference. This comprehensive guide aims to provide tech enthusiasts and professionals with a deep dive into the world of coaxial cables, covering their design, materials, usage, customization options, and the latest technological advancements.

Understanding Coaxial Cables: Design and Materials

Coaxial cables are designed with a core conductor surrounded by an insulating layer, a conductive shield, and an outer layer of insulation. The electrical characteristics of a coaxial cable, such as impedance and attenuation, are critically dependent on the geometric structure of these internal components. It’s vital that these characteristics are not compromised during handling and installation to maintain optimal signal distribution.

Proper Handling and Installation: Preserving Electrical Characteristics

Mishandling a coaxial cable, such as trampling, improper pulling, or excessive bending, can render it dysfunctional. Often, these defects go unnoticed until after the wiring process is completed, leading to time-consuming and costly rework. Especially in challenging work environments like roofs, low attics, or over stairs, where accidental stepping on or knotting of the cable is common, using a damaged cable is not recommended. Instead, salvage the functional parts of the cable to create patch cords or TV-socket cables.

Optimizing Coaxial Cable Electrical Characteristics through Proper Installation

The electrical performance of a coaxial cable is pivotal in achieving high-quality signal transmission. To maintain this, proper handling and installation are crucial. Any mishandling can adversely affect the cable’s core characteristics, such as impedance and attenuation.

During installation, special attention should be paid to the cable’s bending radius. Sharp bends or twists can significantly alter these electrical properties. This is especially crucial in confined spaces or in-wall installations, where maintaining the structural integrity of the cable is essential for optimal performance.

Enhanced Coaxial Cable Traction and Bending Tests

In our advanced traction tests, we assess the durability and resilience of coaxial cables under stress. For instance, an Aluminum-Magnesium Alloy Coaxial Cable maintains its integrity and electrical characteristics up to the point of breaking under a 20 Kg test load. On the other hand, a Tinned Copper Coaxial Cable shows a more gradual degradation under the same conditions, with its mechanical structure impacting its electrical performance.

A notable finding is the internal conductor’s response to traction. When subjected to a 13 Kg load, the conductor elongates significantly, about 15cm, compromising the cable’s electrical parameters, even if it remains physically intact.

We meticulously analyze the impact of bending on coaxial cables, especially when they are subjected to acute angles like 90 degrees. Our testing reveals that physical stress, such as a 20 Kg pull or a 90° bend, can cause a substantial deviation from the ideal 75 Ohm ± 3 Ohm range, highlighting the critical impact of careful cable handling on the cable’s performance.

Expert Cable Assembly and User Socket Considerations

Proper cable assembly is crucial for maintaining the integrity of the coaxial cable system. Our comprehensive tests, conforming to CE standards, have revealed that the choice of connectors significantly influences the system’s shielding efficiency. With medium or low-quality connectors, shielding efficiency can plummet from 100 dB to 70 dB, exposing the system to external interference. Conversely, high-quality connectors, such as PPCs, maintain over 100 dB of shielding efficiency, ensuring robust protection against interference, moisture, and oxidation. Given their minimal cost impact, we strongly advise opting for high-quality compression connectors to ensure system reliability.

The user socket, being the terminal point of the distribution system, often encounters challenges like inappropriate twisting or tight bends. To mitigate the formation of negative notches in the attenuation curve, especially in tighter spaces of older systems, careful installation is imperative. We recommend using coaxial cables with a 5 mm overall diameter for easier handling and reduced risk of damage. For newer systems with larger flush-mounted boxes, this provides additional flexibility in cable routing, allowing for gentler curves and less strain on the cable.

Importance of Proper Unwinding and Storage

To prevent damage, it’s crucial to unwind coaxial cables correctly. Improper unwinding can lead to spirals and knots, adversely affecting the cable’s impedance. We recommend using specialized cable unwinders, like our ARIANNA model, to prevent these issues. For those without a professional unwinder, carefully unwinding by inserting your forearms into the coil and rotating it can be an alternative. For cable reels, using a tripod helps maintain the cable’s integrity.

Importance of Correct Bending and Installation

When installing coaxial cables, avoid tight bends or angles, especially in corners or around door frames. Adhering to the minimum bending radius, as specified in our catalog and datasheet, is crucial. For exposed installations, use suitable cable ties or fairleads to prevent ring bottlenecks, which can significantly impact signal return loss (SRL).

Choosing the Right Connectors

Connectors play a vital role in the overall performance of a coaxial cable system. Using high-quality compression connectors, like PPCs, can ensure over 100 dB of shielding efficiency, thus protecting the system from external interference and moisture.
