The Ultimate Buying Guide for Coaxial Cables
Coaxial cables, often called “coax cables,” are essential for sending signals over long distances. Think of your TV, internet modem, or satellite dish—they all need these special wires. Choosing the right one makes a big difference in signal quality. This guide helps you pick the best cable for your needs.
Key Features to Look For
When buying a coax cable, several features matter most for good performance.
1. Impedance (Ohms)
Impedance is the cable’s resistance to the signal. Most home electronics use cables with 75 Ohms of impedance. This is standard for TV and video signals. Always check that the cable matches the device’s requirement. Using the wrong impedance causes signal loss and fuzzy pictures.
2. Shielding Level
Shielding stops outside noise (like from power lines or Wi-Fi) from messing up your signal. Good cables have multiple layers of shielding. Look for cables with foil wrapping and a braided metal layer. Better shielding means a clearer signal.
3. Connector Type
The ends of the cable are the connectors. The most common type is the F-connector, which screws onto devices like cable boxes and modems. Ensure the connectors are high quality, usually made of brass or gold-plated metal. Gold plating resists rust better.
Important Materials That Matter
The materials inside the cable greatly affect how well it works.
The Center Conductor
This is the wire right in the middle that carries the signal. Solid copper conductors offer the best performance because they conduct electricity very well. Copper-clad steel (CCS) is cheaper, but it does not carry high-frequency signals as effectively as solid copper.
The Dielectric Insulator
This material surrounds the center conductor. It keeps the conductor in the exact center of the cable. High-quality cables use foam polyethylene (PE) for the insulator. This material helps keep the signal strong over long runs.
The Jacket (Outer Sheath)
The jacket protects the inner parts from damage, moisture, and weather. For indoor use, PVC jackets are common. If you run the cable outdoors or bury it, you need a plenum-rated or UV-resistant jacket to prevent cracking.
Factors That Improve or Reduce Quality
What makes a coax cable great or terrible?
Factors That Improve Quality:
- Thicker Gauge (e.g., RG-6 vs. RG-59): RG-6 cables are thicker than RG-59 cables. Thicker cables handle higher frequencies and longer distances better, reducing signal loss (attenuation). Use RG-6 for modern cable TV and internet.
- High-Quality Connectors: Compression fittings create a tight, weatherproof seal. They are much better than cheap crimp-on connectors.
- Low Attenuation Rate: This measures how much signal strength the cable loses per 100 feet. Lower numbers are always better.
Factors That Reduce Quality:
- Kinks and Bends: Do not bend the cable sharply. Tight bends crush the internal structure, instantly degrading the signal quality.
- Poor Shielding: Cables with only a single layer of thin foil shielding let in a lot of interference.
- Cheap Center Conductor: Using CCS instead of solid copper increases signal loss, especially for high-speed internet.
User Experience and Use Cases
How you use the cable dictates what type you should buy.
Cable Television (CATV) and Satellite
For modern HD TV and digital cable, you need an RG-6 cable with 100% coverage shielding. This handles the high bandwidth required for clear pictures.
Internet Modems (Broadband)
High-speed internet demands the best signal integrity. Always use a high-quality RG-6 cable with solid copper center conductors. Shorter runs are always better for internet performance.
Older Analog Video (CCTV)
For older, lower-frequency uses like basic closed-circuit television (CCTV), a thinner RG-59 cable might work. However, RG-6 is usually recommended even here for future-proofing.
10 Frequently Asked Questions (FAQ) About Coaxial Cables
Q: What is the difference between RG-59 and RG-6 cable?
A: RG-6 cable is thicker than RG-59 cable. RG-6 handles higher frequencies and signal loss better, making it the standard for modern internet and HD cable. RG-59 is better suited for short runs or older, lower-frequency video signals.
Q: What does “75 Ohm” mean?
A: 75 Ohms is the standard electrical resistance measurement for video and data signals in homes. You must use 75 Ohm cables with your TV, cable modem, or satellite receiver for them to work correctly.
Q: Can I use a coax cable outdoors?
A: You can, but you must use a cable specifically rated for outdoor use. Look for jackets labeled “UV resistant” or “Direct Burial” to stop sunlight and moisture from destroying the cable over time.
Q: What is attenuation?
A: Attenuation is the signal loss that happens as the signal travels down the cable. Longer cables have more attenuation. Good quality cables have lower attenuation rates.
Q: Are gold-plated connectors worth the extra cost?
A: Yes, gold plating resists corrosion much better than standard nickel or brass connectors. This helps maintain a strong connection for many years, especially in humid environments.
Q: What is the best way to connect two coax cables together?
A: You should use a barrel connector, which screws onto the ends of both cables. For the best signal, keep the number of connections to an absolute minimum.
Q: How tightly should I screw on the F-connector?
A: You need to tighten the connector until it is snug and you feel resistance. Do not overtighten it, as this can damage the threads on your device or the connector itself.
Q: Does cable length affect my internet speed?
A: Yes. Longer cables cause more signal loss (attenuation). Shorter cables provide a stronger, cleaner signal to your modem, which supports faster, more stable internet speeds.
Q: What is “quad shielding”?
A: Quad shielding means the cable has four layers of protection—usually two layers of foil and two layers of braided metal. This offers superior protection against external interference compared to standard dual shielding.
Q: Should I buy pre-made cables or bulk cable and connectors?
A: For most users, buying pre-made, tested cables of the exact length you need is the easiest and most reliable option. Bulk cable and connectors are only necessary if you need very long, custom runs or are installing many connections professionally.
