Coaxial cable has been around for decades, yet confusion still follows it everywhere. Some people dismiss it as outdated. Others assume all coax works the same. These ideas spread fast and cause poor buying choices. They also lead to weak signal performance and wasted money.
This article clears the fog. We will break down common myths and explain what actually happens inside coaxial lines. You will get real answers that help you make better decisions for home and business networks.
Busting Common Misconceptions about Coaxial Cable
Coaxial cable myths often grow from half-truths and outdated habits. Many claims sound logical at first glance. The truth usually sits deeper. Each misconception below explains what people believe and why that belief misses the mark in real installations.
Misconception: The Tighter the Braid, the More Effective the Shielding
Shielding matters, but a tighter braid alone does not guarantee better protection. Shield quality depends on material type, coverage consistency, and proper grounding. Loose manufacturing tolerances can ruin performance even with dense braid. Good coaxial cabling balances braid design with foil layers and conductor quality to block interference reliably.
Another overlooked issue is braid consistency along the cable length. Gaps, overlaps, or uneven tension weaken shielding performance. Even a tightly woven braid fails if foil layers tear or separate during installation. Real shielding strength comes from balance, not pressure alone.
Misconception: Series-6 (RG-6) Coax Is an Updated Replacement for Series-59 (RG-59) Coax
RG-6 did not replace RG-59 across every use. Each serves a specific role. RG-6 supports higher frequencies and longer runs. RG-59 still fits short video paths. Using RG-6 coaxial cable where RG-59 belongs can create connection issues instead of solving them.
Many installers assume newer equals better in every situation. That thinking causes fitment problems with legacy connectors and equipment ports. RG-59 still serves short analog runs well. Replacing it blindly can introduce attenuation where none existed before.
Misconception: Quad-Shielded Coaxial Cable Provides Faster Performance over Longer Distances than Dual-Shielded
Shielding blocks interference. It does not increase speed. Quad shielding helps in noisy spaces like factories. It does nothing to boost signal speed or distance. Cable length, conductor size, and signal source matter more. Buying bulk coax cable based on shielding alone often leads to disappointment.
Speed claims often ignore real deployment conditions. Fiber requires specialized hardware and careful termination. Coax supports high speeds using existing infrastructure, which reduces conversion loss. In many homes, coax delivers stable performance without the installation errors that fiber sometimes faces.
Misconception: Optical Fiber Is Always Faster Than Coax
Speed depends on equipment and use case. Fiber shines in long-distance backbones. Coax excels in last-mile delivery and in-home distribution. Modern coax supports high data rates when paired with the right hardware. Dismissing coax ignores how internet providers still rely on it daily.
This belief ignores how cable internet still reaches millions daily. Providers upgrade electronics while keeping coax lines active. Removing coax would require massive rebuilds. Continued investment proves its relevance. Obsolete systems do not receive this level of ongoing support.
Misconception: Coaxial Cable Is Obsolete
Coax continues to power cable internet, television, and radio systems worldwide. Service providers invest heavily in coax networks. Homes still rely on RG6 cable for internet for stable and consistent service. Obsolete tools fade away. Coax clearly has not done that.

Misconception: Coaxial Cable Is a Commodity Item That Will Perform the Same, Regardless Of Price
Cheap coax cuts corners. Thin conductors, poor shielding, and weak jackets cause signal loss. Higher-quality cables cost more for good reason. Reliable coax cable for router connections depends on solid construction. Price often reflects performance and lifespan, not branding tricks.
Manufacturing shortcuts hide beneath identical jackets. Lower-cost cables may use steel cores or thin copper plating. These choices raise resistance and signal loss. Long-term reliability suffers. Performance gaps often appear months after installation, not on day one.
Misconception: Coaxial Cable Does Not Need To Be Grounded
Ungrounded coax invites noise and safety risks. Electrical surges can damage devices and harm users. Grounding stabilizes signal quality and protects equipment. Proper grounding remains a basic requirement, not an optional step. Skipping it creates problems that show up later.
Grounding also reduces static buildup that causes intermittent signal drops. Many unexplained outages trace back to floating grounds. Proper bonding stabilizes voltage reference points. Skipping grounding may work briefly, but problems surface during storms or power fluctuations.
Misconception: Coaxial Cable Can’t Operate At Today’s Network Speeds
Modern standards push coax far beyond old limits. Technologies like DOCSIS allow high throughput over existing lines. Homes receive fast broadband using RG-6 coaxial cable every day. Speed limits usually come from outdated hardware, not the cable itself.
Network speed limits usually come from outdated splitters or old modems. Coax itself supports wide frequency ranges. Upgrading endpoints often restores full performance. Blaming the cable delays for simple fixes that could immediately improve throughput and stability.
Misconception: Coaxial Cable Can Transmit a Signal Farther Than Ethernet Cable Can
Both cables have distance limits. Ethernet supports long runs with switches. Coax supports long runs with amplifiers. Neither wins by default. Performance depends on signal type and setup. Assuming coax always travels farther leads to poor network planning and wasted materials.
Distance claims ignore signal quality requirements. Longer coax runs need active components to stay clean. Ethernet uses switches to regenerate data. Both systems rely on proper design. Assuming distance superiority leads to poor layouts and unnecessary signal loss.
Final Words
Misconceptions cloud good decisions. Coaxial cable remains reliable, flexible, and powerful when used correctly. Understanding facts instead of myths protects performance and budgets.
