Best Coax Cable for TV: The Complete Buying Guide

Published by Wassalat Technical Team

Whether you're connecting a TV antenna, setting up cable television, or installing a satellite dish, the coaxial cable you choose directly affects your picture and sound quality.

This comprehensive guide explains everything you need to know about selecting coaxial cables for TV applications—from antenna connections to 4K cable TV and satellite installations.

Why Coax Choice Matters for TV

Your TV signal travels through coaxial cable from the source (antenna, cable provider, or satellite dish) to your television. The cable quality determines:

• ? Picture clarity – Sharp, clear images with no artifacts
• ? Sound quality – Clear audio with no interference
• ? Channel availability – All channels come through reliably
• ? Signal strength – No pixelation or dropouts
• ? Internet speed – For cable broadband internet

The 75Ω Standard

All TV equipment uses 75Ω impedance. This includes:

• ? Televisions and set-top boxes
• ? Satellite receivers and dishes
• ? Cable modems and routers
• ? TV antennas
• ? Splitters and distribution amplifiers

Using a 50Ω cable (like RG-58 or LMR-400) will cause impedance mismatch, signal reflections, and poor TV reception. Always use 75Ω cables for TV applications.

RG6: The TV Standard

RG6 is the industry standard for TV applications. It's the cable used by cable companies and satellite installers worldwide.

Specifications

RG6 Advantages

• ✅ Industry standard – Used by cable and satellite companies
• ✅ Excellent performance – Low signal loss
• ✅ Good frequency range – Supports up to 3 GHz
• ✅ Affordable – Reasonable cost per foot
• ✅ Widely available – Easy to find at any hardware store
• ✅ Easy to install – Standard F-Type connectors fit perfectly

RG6 Disadvantages

• ❌ Limited distance – Not suitable for runs over 200 feet
• ❌ Less flexible than RG59 – Slightly stiffer

RG59: When to Use It

RG59 is an older, thinner cable that was once the standard for TV. Today, it's mostly used for short connections.

Specifications

When to Use RG59

• ✅ Short patch cables – Under 10 feet between devices
• ✅ DIY antenna connections – Short runs from antenna to TV
• ✅ Temporary setups – Quick and easy connections
• ✅ Tight spaces – More flexible than RG6

When NOT to Use RG59

• ❌ Long runs – Over 50 feet
• ❌ Satellite TV – Too much loss at satellite frequencies
• ❌ Cable broadband internet – Insufficient for high-speed data
• ❌ 4K TV – Can't handle the high bandwidth

RG11: For Long Runs

RG11 is a thick, low-loss cable designed for long-distance TV signal distribution.

Specifications

When to Use RG11

• ✅ Long cable runs – Over 200 feet
• ✅ Main trunk lines – Distribution in large buildings
• ✅ Multi-dwelling units – MDUs with central distribution
• ✅ Commercial installations – Hotels, hospitals, schools

Shielding Types Explained

TV signals are susceptible to interference from electrical devices, power lines, and other signals. Better shielding means better picture quality.

1. Single Shield (Foil Only)

Coverage: 100%

Best For: Indoor, low-interference areas

Not Recommended For: Satellite, long runs, outdoor

2. Dual Shield (Foil + Braid)

Coverage: ≈100%

Best For: Most residential installations

Recommended: Good balance of cost and performance

3. Quad Shield (Foil + Braid + Foil + Braid)

Coverage: 100%

Best For: Satellite TV, high-interference areas

Recommended: Best protection, especially for satellite and outdoor

Cable by Application

1. Cable TV (CATV)

Recommended Cable: RG6 (Dual Shield)

Why: Cable TV signals are typically under 1 GHz. RG6 with dual shield provides excellent performance at a reasonable cost.

Max Distance: 150-200 feet

2. Satellite TV

Recommended Cable: RG6 (Quad Shield)

Why: Satellite TV operates at higher frequencies (950-2150 MHz) and is more susceptible to interference. Quad shield provides maximum protection.

Max Distance: 100-150 feet

3. TV Antenna

Recommended Cable: RG6 (Dual or Quad Shield)

Why: Antenna signals are weak and need the best cable to preserve signal strength. Outdoor antennas also need UV-resistant cable.

Max Distance: 150-200 feet

4. Cable Broadband Internet

Recommended Cable: RG6 (Dual Shield)

Why: Cable internet uses DOCSIS technology with frequencies up to 1 GHz. RG6 provides sufficient bandwidth.

Max Distance: 150-200 feet

5. Multi-Dwelling Units (MDU)

Recommended Cable: RG11 (Main trunk), RG6 (Drops)

Why: MDUs require long runs from the head-end to individual units. RG11 provides low loss for the main line, RG6 for final connections.

F-Type Connectors Guide

F-Type connectors are the standard for TV applications. Choose the right type for your installation:

1. Screw-On (Twist-On) Connectors

Installation: Screws onto prepared cable

Quality: Basic

Best For: Temporary connections, DIY

Not Recommended For: Permanent installations

2. Crimp-On Connectors

Installation: Crimped with a special tool

Quality: Good

Best For: Professional installations

Recommended: Reliable and durable

3. Compression Connectors

Installation: Compressed with a special tool

Quality: Excellent

Best For: Professional, weatherproof installations

Recommended: Best for outdoor and long-term use

Frequently Asked Questions (FAQ)

1. What is the best coaxial cable for TV?

RG6 is the best coaxial cable for most TV applications. It offers excellent performance, low signal loss, and supports up to 3 GHz frequencies.

2. Can I use RG59 for cable TV?

RG59 is not recommended for cable TV. It has higher signal loss than RG6 and may cause pixelation or channel loss. Use RG6 instead.

3. What is the best coax cable for satellite TV?

RG6 with quad shielding is the best choice for satellite TV. It provides maximum protection against interference and low signal loss at satellite frequencies (950-2150 MHz).

4. How long can a TV coax cable be?

RG6 can run up to 200 feet for cable TV and 150 feet for satellite TV. For longer runs, use RG11 or add a signal amplifier.

5. What is the difference between RG6 and RG11 for TV?

RG6 is the standard for most TV installations. RG11 has lower signal loss and can run much longer distances (up to 500 feet), but is thicker, stiffer, and more expensive.

6. Do I need quad-shield coax for TV?

Quad-shield is recommended for satellite TV and installations in high-interference areas. For standard cable TV, dual-shield is usually sufficient.

7. Can I use TV coax for internet?

Yes, the same RG6 cable used for TV can also carry cable broadband internet signals (DOCSIS).

8. What type of connector does TV coax use?

TV coax typically uses F-Type connectors. These are the screw-on or compression connectors found on TVs, set-top boxes, and cable modems.

9. Does cable length affect TV picture quality?

Yes. Longer cable runs have more signal loss, which can cause pixelation, ghosting, or loss of channels. Keep cable runs as short as possible.

10. Can I connect two TV coax cables together?

Yes, using a barrel connector (F-Type coupler). However, each connection adds signal loss. Try to use a single continuous cable when possible.

11. What is the best coax cable for 4K TV?

For 4K TV, use RG6 with dual or quad shielding. 4K signals require high bandwidth, and RG6 provides the necessary performance.

12. Can I use RG6 for my TV antenna?

Yes. RG6 is excellent for TV antennas. It preserves weak antenna signals better than RG59.
