When setting up your TV or internet connection, one of the most important components to consider is the coaxial antenna cable. These cables are responsible for transmitting signals from your antenna or other devices to your television or modem. Choosing the right coaxial antenna cable can make a big difference in the quality of your signal and, ultimately, your viewing or browsing experience. In this blog, we will discuss some helpful tips for selecting the best coaxial antenna cable for your setup.
Understanding Coaxial Antenna Cables
Before diving into how to choose the right cable, it’s important to understand what coaxial antenna cables are and how they work. Coaxial cables are designed to transmit radio frequency (RF) signals with minimal loss. The cable consists of several layers, including:
- Inner conductor: This is usually made of copper and carries the signal.
- Insulating layer: This layer surrounds the inner conductor and prevents interference.
- Outer conductor (shielding): Made of metal, this part helps protect the signal from outside interference.
- Outer insulation: The final layer protects the cable from external damage.
Coaxial cables are often used for television antenna setups, internet connections, and satellite systems. Their ability to transmit high-frequency signals with minimal interference is why they are commonly used in both home and commercial setups.

Tips for Choosing the Best Coaxial Antenna Cable
1. Determine the Right Cable Length
One of the first things you should consider is the length of the coaxial antenna cable you need. The length will depend on the distance between your antenna and the device you’re connecting it to, such as a TV or modem. If the cable is too short, you may not be able to position your antenna in the ideal location for maximum signal reception. On the other hand, if the cable is too long, it can result in unnecessary signal loss.
To find the right length, measure the distance from your antenna to your TV or modem, and add a little extra length to ensure flexibility when positioning the cables. Be sure not to go overboard, as excess cable can lead to a decrease in signal strength.
2. Choose the Right Cable Type (RG6 vs. RG59)
When selecting a coaxial cable, you’ll encounter different types, with RG6 and RG59 being the most common. These numbers refer to the cable’s specifications and the thickness of the cable’s core.
- RG6 cables are the most commonly used for TV, internet, and satellite connections. They offer better shielding and lower signal loss over long distances. If you are setting up a cable for high-definition (HD) television or high-speed internet, RG6 is your best choice.
- RG59 cables are thinner and have more signal loss over long distances. They are often used for shorter runs and are more common in older TV setups or less demanding applications.
In most cases, RG6 will be the better option for a reliable and strong signal. It is also more widely available and affordable.
3. Check the Shielding of the Cable
Shielding plays a critical role in protecting the signal from interference. Interference can come from various sources, such as electrical appliances, Wi-Fi networks, or even nearby cables. If your coaxial cable lacks proper shielding, your signal may become weak, leading to poor picture quality or slower internet speeds.
When choosing a coaxial antenna cable, make sure to look for one with good shielding. There are typically two types of shielding:
- Single shielding: A single layer of shielding is usually enough for short cable runs in areas with minimal interference.
- Double shielding: Double-shielded cables have two layers of shielding, offering superior protection against interference. These are ideal for long cable runs or areas with high levels of electromagnetic interference (EMI).
If you live in an area with lots of electronic devices or large metal objects, double shielding is a better choice to ensure high-quality signal transmission.
4. Consider the Cable’s Impedance
Impedance is an important factor when choosing a coaxial cable, especially for TV and internet setups. Coaxial cables typically come in two standard impedance values:
- 75 ohms: This is the standard impedance for most TV and satellite antenna systems. If you’re using the cable for cable TV, internet, or satellite systems, a 75-ohm cable is what you need.
- 50 ohms: These cables are typically used for radio frequency (RF) communication systems, such as Wi-Fi antennas or ham radio setups.
Most consumer-grade setups, like TV and internet connections, will require a 75-ohm coaxial cable. Be sure to check the impedance specification on the packaging or product description before purchasing.
5. Look for High-Quality Connectors
The connectors at the ends of your coaxial antenna cable are just as important as the cable itself. These connectors are responsible for making the connection between your antenna and your device, so having high-quality connectors ensures a strong and reliable signal.
Most coaxial cables come with F-type connectors, which are commonly used for TV and internet setups. These connectors screw onto your antenna or TV port and provide a secure connection. Make sure the connectors are made from durable materials like gold or nickel-plated brass, as these are less likely to corrode and provide a more stable connection.
6. Check for Flexibility and Durability
Coaxial cables need to be flexible enough to bend around corners and tight spaces, but they also need to be durable to withstand wear and tear. If you’re running the cable outdoors or through areas where it might be exposed to the elements, look for a weather-resistant or outdoor-rated coaxial cable. These cables are designed with a protective outer layer that can withstand harsh conditions like rain, wind, and UV rays.
For indoor use, flexibility and ease of installation are key. A cable that is too stiff may be difficult to manage, while one that is too flimsy may not offer long-lasting performance. Find a balance that suits your setup.
7. Consider the Cost
While it’s important to invest in a high-quality coaxial antenna cable, the price doesn’t always guarantee the best performance. You can find reasonably priced coaxial cables that offer great quality without breaking the bank. Avoid excessively cheap cables, as they may be poorly made and prone to signal loss or damage. On the other hand, extremely expensive cables may not provide significantly better performance for standard TV and internet setups.
Instead, focus on finding a cable that balances quality and cost. Read product reviews and check for customer feedback to ensure the cable you’re considering offers good value for your money.
8. Look for a Warranty or Guarantee
A warranty or satisfaction guarantee is a good sign of a high-quality product. It shows that the manufacturer believes in the durability and reliability of their cable. When purchasing a coaxial antenna cable, check if the product comes with a warranty or satisfaction guarantee. This way, if the cable doesn’t meet your expectations or malfunctions, you’ll be able to get a replacement or refund.
Conclusion
Choosing the best coaxial antenna cable for your setup might seem simple, but there are several factors to consider to ensure a high-quality signal and long-lasting performance. By paying attention to the cable’s length, type, shielding, impedance, connectors, and durability, you can make an informed decision that meets your needs. Whether you’re setting up for TV, internet, or satellite services, selecting the right coaxial cable will ensure you get the most out of your equipment and enjoy clear, reliable signal transmission.
