A Beginner’s Guide to Choosing the Right Antenna Cables for Reliable Connectivity

When setting up a communication system, selecting the right antenna cable might not be the first thing that comes to mind. However, did you know it can significantly impact your signal quality? Whether you’re working on industrial deployments or remote locations, choosing the right cable is crucial to ensuring reliable connectivity and minimizing signal loss. A poor choice can lead to weak signals, inefficiencies, and even system failures.

So, how can you ensure you’re using the best cable for your needs?

At TEKTELIC, with over 15 years of experience deploying thousands of gateways worldwide, we understand that even small details, like cable selection, can greatly influence performance. In this guide, we’ll share practical insights to help you choose the right antenna cable for reliable and efficient communication.

What Are Antenna Cables?

Antenna cables are essential components in communication systems that transmit signals between devices such as antennas and receivers. They come in various types and specifications, each designed to meet specific performance and environmental needs. Choosing the right antenna cable can significantly impact the efficiency and reliability of your communication system, making it a crucial decision in any deployment.

Common Challenges That Impact Signal Performance

Building a robust communication system comes with its share of challenges. Signal quality can degrade due to several factors, such as:

• Insertion Loss: All cables introduce some signal loss, measured in decibels (dB). To ensure smooth operations, aim for a total signal loss of less than 1.5 dB. Anything higher can weaken signals and reduce efficiency.
• Connector Loss: Connectors, which join cables to equipment, also cause some signal loss, typically around 0.25 to 0.3 dB each. Proper planning helps keep the total system loss within acceptable limits.
• Cable Length and Quality: Longer cables result in higher signal loss. Choosing high-quality cables with minimal loss per meter is critical to maintaining performance.
• Environmental Challenges: Harsh environments, including extreme temperatures, dust, and moisture, can affect cable longevity and reliability. Selecting durable cables is essential.

How to Choose the Right Cable for Your Needs

To address these challenges, consider the following best practices when selecting an antenna cable:

1. Understand Insertion Loss:
   • Insertion loss measures the reduction in signal strength as it travels through a cable. Ensure total insertion loss remains within your system’s budget.
   • For example, if your system allows a maximum loss of 1.5 dB, allocate this budget wisely between connectors and cables.
2. Select the Right Cable Type:
   • Different cable types have varying levels of signal loss and durability. Compare options to find the best fit:

• Recommended Choices:
  • LMR-400: A solid choice for short-to-medium distances with low insertion loss.
  • Heliax LDF4-50: Ideal for long distances and harsh conditions, providing exceptional durability and signal quality.

1. Consider Environmental Factors:
   • Temperature Resistance: Cables exposed to extreme heat or cold need wide temperature tolerance.
   • Moisture Protection: Proper shielding prevents damage from humidity or water exposure.
   • Physical Durability: UV-resistant cables are recommended for outdoor and industrial settings.

Best Practices for Cable Installation and Maintenance

To maximize cable performance and longevity:

• Use high-quality connectors: Investing in premium connectors ensures better electrical conductivity and reduces signal loss.
• Proper routing: Avoid sharp bends and kinks in the cable that can impact signal transmission and longevity.
• Weatherproofing: Outdoor cables should be protected with butyl tape and telecom-grade silicone to prevent moisture ingress and extend lifespan.
• Routine inspections: Schedule regular maintenance checks to detect and address any wear, corrosion, or damage early.
• Correct installation: Ensure proper torque settings when attaching connectors to prevent mechanical failure and signal degradation.
