How to Choose the Perfect Coax Cable for Internet
A comprehensive guide based on real-world testing and user feedback
What Actually Matters When Shopping
1. True Signal Loss vs. Marketing Claims
Long cable runs can cause significant attenuation. A cable's construction, shielding, and conductor quality dictate its real-world performance.
Look for
Look for RG6 (or better) with high braid and foil shielding, preferably with solid copper or quality copper-clad steel. For critical modem connections, low-loss 50 Ohm cables (for SMA-based equipment) are essential.
Avoid
Thin, cheap RG59 cables; vague claims of 'high speed' with no specs; aluminum-only cores.
2. Environmental Protection
Cables run outdoors or in basements face water, corrosion, and soil acidity. Without proper protection, signal loss and failures occur quickly.
Look for
Seek direct burial/gel-coated options for any underground or outdoor run. Waterproof jackets and connector boots are a must.
Avoid
Indoor-only cables for outdoor use, standard PVC in wet or chemical soils, poor connector seals.
3. Connector Quality & Compatibility
The weakest point in the chain is often the connector. Poorly attached, wrongly sized, or incompatible ends can render even a great cable useless.
Look for
Compression F-type for standard internet/TV; SMA for RF/4G/5G. Gold/nickel plating, firm fit, weatherproofing for exposures.
Avoid
Press-on or push-fit connectors, missing male/female adapters required by your router/modem.
Your Decision Framework
A great cable is the backbone of reliable internet. Focus on your environment, device compatibility, and installation length to avoid frustrated troubleshooting later.
Map Your Cable Path
Trace the physical route: length, obstacles, bends, indoor/outdoor sections. Overestimate length for slack.
- • How far is your modem/router from the ISP hookup?
- • Will the cable run outdoors, underground, or in-wall?
- • Are sharp bends or extreme temperatures a factor?
Verify Device Compatibility
Check your modem/router and wall/ISP ports for connector type (usually F-type for cable, SMA for specialty modems/antennas). Don't assume one-size-fits-all.
- • Do you need F-type or SMA connectors?
- • Is your equipment rated for 50 Ohm or 75 Ohm cable?
- • Will you need adapters or extension couplers?
Balance Length with Quality
Longer cables mean more signal loss—so prioritize quality for long runs. Avoid using overly long cables for short distances.
- • Does your install require direct burial/gel-coating?
- • Is premium shielding worth the cost at your run length?
- • Can you minimize splitters/adapters to prevent loss?
Avoid These Common Mistakes
1. Choosing the Cheapest Cable
• Why problematic: Budget cables often cut corners on shielding and core materials—leading to signal dropouts, especially over longer distances.
• Better approach: Balance price with specs and real-world customer reviews for your usage length.
2. Using Indoor Cable Outdoors or Underground
• Why problematic: Standard jackets break down, inviting water and failure.
• Better approach: Use proper direct burial or waterproof cables for any harsh or wet environments.
3. Ignoring Connector Type
• Why problematic: SMA and F-type look similar but are not interchangeable. Incorrect ends mean wasted time and money.
• Better approach: Double-check both device and cable connector requirements—and get adapters as needed!
Budget vs Reality: What You Actually Get
Under $25
Reality: Short-to-medium length RG6 cables (25-50ft), usually with decent shielding and basic connectors, good for most typical home or apartment internet/TV runs.
Trade-offs: Limited weatherproofing; may lack premium connectors or outdoor-ready jackets.
Sweet spot: Ideal for low-cost, simple indoor installs.
$25-$70
Reality: Higher-quality cables, often 50-200ft with superior shielding, robust jackets, and better connectors. Some direct burial or weatherproof options available.
Trade-offs: For the longest runs, flexibility or professional-grade burial protection may be slightly limited.
Sweet spot: Best value for most households—get length, shielding, and quality suited to your install without overpaying.
Over $70
Reality: Premium/professional cables for 200ft+ direct burial, industrial-grade or highly specialized (LMR/low loss for RF/SMA).
Trade-offs: You may be paying for overkill in short runs or easy indoor environments.
Sweet spot: Warranted if you need ultra-long or harsh-environment setups.
Pro Tips for Success
1. Before You Buy
Trace your actual cable path (including detours around doors/furniture) and add 20% extra length for safety and flexibility.
2. First Week of Use
Test your internet speeds and streaming stability at different times of day to catch any issues early.
3. Long-term Care
Secure cables to avoid pinching bends, and periodically check outdoor connections for signs of water ingress.
4. When to Upgrade
If you notice progressive slowdown, pixelation, or excessive buffering, check both cable condition and connectors—upgrade if fray, corrosion, or visible damage appears.
