Best Coaxial Cable for TV, Cable Box, Satellite, and Antenna Connections

Published: June 13, 2026

The best coaxial cable for most modern TV, cable box, satellite, and antenna connections is 75-ohm RG6 coaxial cable with F-type connectors. RG6 is widely used because it offers a strong balance of signal performance, availability, connector compatibility, and installation ease.RG59 is common in older analog video and CCTV installations, but RG6 is usually the better choice for new TV and broadband-related wiring. RG11 is useful for long runs where lower signal loss matters. For the broader technical comparison, see the types of coaxial cable guide.

What Cable Is Used for TV Connections?

Most TV-related coax connections use 75-ohm coaxial cable. In residential installations, that usually means RG6.

TV Connection	Recommended Cable	Common Connector
Cable TV wall outlet to TV/cable box	RG6 75-ohm	F-type
Cable box to wall outlet	RG6 75-ohm	F-type
Satellite dish to receiver	RG6 75-ohm	F-type
Outdoor TV antenna to indoor TV	RG6 75-ohm	F-type or regional antenna connector
Long outdoor run	RG11 75-ohm	F-type
Older analog video/CCTV	RG59 75-ohm	BNC, RCA, or F-type

If you are buying one cable for a modern TV setup, choose RG6 unless your equipment or installer specifies something else.

Fast Recommendation by Buyer Type

Buyer Type	Best Starting Choice	Why
Apartment renter replacing a short TV cable	RG6 with F-type connectors	Easy, common, suitable for cable TV and many antenna setups
Homeowner wiring an outdoor antenna	Outdoor-rated RG6	Better weather resistance than an indoor patch cable
Long run from antenna to TV area	RG11 or low-loss RG6 after checking distance	Lower loss may matter over long paths
Cable modem user	Provider-approved RG6	Cable internet service can be sensitive to poor connectors and damaged cable
Legacy CCTV user	RG59 may be acceptable	Many older analog CCTV systems were designed around RG59

This is a practical starting point, not a substitute for local code, service provider rules, or installer requirements.

RG6 vs RG59 for TV

RG6 and RG59 are both 75-ohm coaxial cables, but they are not identical.

Feature	RG6	RG59
Typical use	Modern TV, cable, satellite, antenna, cable modem	Older analog video, CCTV, short low-frequency runs
Approx. diameter	6.9 mm / 0.27 in	6.1 mm / 0.24 in
High-frequency performance	Usually better	Usually higher loss
Best for new TV wiring	Yes	Usually no
Flexibility	Moderate	Slightly easier to bend

For digital TV, satellite, and cable service, RG6 is generally preferred. RG59 may work for short legacy video connections, but it is not the first choice for new installations.

When Should You Use RG11?

Use RG11 when the cable run is long and signal loss becomes a concern. RG11 is a 75-ohm coaxial cable like RG6, but it is thicker and typically has lower loss. If connector fit or cable diameter is the main issue, check the coax cable sizes and diameter chart. RG11 is useful for:

Scenario	Why RG11 Helps
Long outdoor antenna runs	Lower loss over distance
Long cable TV drops	Better signal retention than smaller coax
Underground or distribution runs	Suitable for long backbone paths when properly rated
Satellite distribution	Helpful where distance is significant

RG11 is not usually needed for short indoor patch cables. It is harder to bend, harder to hide, and requires compatible connectors.

What Connector Does a TV Antenna Use?

In many TV, cable, satellite, and antenna setups, the connector is an F-type connector. It is the threaded metal connector with a center pin. Some regions and devices may use IEC-style antenna connectors, sometimes called TV aerial connectors. The exact connector depends on the country, antenna, TV, and wall outlet.

Connector	Common Use
F-type	Cable TV, satellite, cable modem, many TV antennas
IEC/PAL-style TV connector	Common in some regional TV antenna systems
BNC	CCTV, professional video, test equipment
RCA	Older analog video/audio devices

For North American-style cable TV and cable modem connections, F-type is the most common.

Is HDMI the Same as Coaxial Cable?

No. HDMI and coaxial cable serve different roles.

Cable	What It Carries	Common Use
Coaxial cable	RF signals for TV, antenna, satellite, or cable internet	Wall outlet to TV/cable box/modem
HDMI cable	Digital audio and video	Cable box, streaming device, or game console to TV

A cable box may use coax from the wall and HDMI to the TV. These are not interchangeable.

Best TV Cable Wire by Scenario

Use Case	Recommended Cable	Connector	Note
Basic cable TV	RG6 75-ohm	F-type	Standard choice
Digital TV antenna	RG6 75-ohm	F-type or regional connector	Use outdoor-rated cable outside
Satellite TV	RG6 75-ohm	F-type	Check satellite provider requirements
Long outdoor run	RG11 75-ohm	F-type	Lower loss, less flexible
Cable modem near TV area	RG6 75-ohm	F-type	Same cable family as cable TV
Legacy CCTV	RG59 75-ohm	BNC or RCA	Usually for analog systems

Indoor, Outdoor, and Plenum Cable

Cable type is not only about RG number. Jacket rating matters.

Rating or Style	When It Matters
Indoor cable	Short indoor TV or modem patch cables
Outdoor-rated cable	Exposed antenna, satellite, or exterior wall runs
Direct-burial cable	Underground installation
Plenum-rated cable	Air-handling spaces where code requires it
Riser-rated cable	Vertical building runs where required by code

Do not use a basic indoor cable outdoors for a permanent installation. Sunlight, water, and temperature can damage the jacket over time.

Shielding: Standard vs Quad-Shield RG6

Shielding helps protect the signal from interference. RG6 cable may be sold as standard shielded, dual-shield, tri-shield, or quad-shield. Quad-shield RG6 may be useful when:

The cable runs near electrical noise
The installation is in a dense signal environment
The cable provider or satellite installer recommends it
Signal leakage or ingress is a concern

Quad-shield cable is thicker and needs connectors designed for quad-shield RG6.

Common Mistakes When Buying TV Coax Cable

Do not buy a cable only because the connector fits. Check whether it is RG6, RG59, or RG11 and whether it is rated for the installation environment. If you are not sure the cable is actually coax, compare it with the visual checklist in what does a coax cable look like. Avoid using damaged coax with bent center pins, crushed jackets, loose connectors, or sharp bends. Coaxial cable performance depends on its internal geometry, so physical damage can affect signal quality. Also avoid assuming that a coaxial cable replaces HDMI. In a modern TV setup, coax often brings service to the cable box or TV tuner, while HDMI carries video from a device to the TV.

Installation Quality Matters More Than the Label Alone

A high-quality RG6 cable can still perform poorly if it is installed badly. Watch for:

Loose F-type connectors
Bent or recessed center pins
Sharp bends or crushed cable
Indoor cable used permanently outdoors
Too many splitters in the signal path
Old wall plates or splitters not rated for the signal range
Corrosion on outdoor connectors

For cable internet or satellite service, a poor connector or splitter can cause intermittent problems even when the cable type is correct.

FAQ

What is the best coaxial cable for TV?

RG6 75-ohm coaxial cable with F-type connectors is the best general choice for modern TV, cable box, satellite, and antenna connections.

Is RG6 or RG59 better for TV?

RG6 is usually better for modern TV, satellite, cable, and antenna use because it generally has lower high-frequency loss than RG59.

Can I use RG59 for TV?

RG59 may work for short or older analog video runs, but RG6 is usually preferred for modern TV and cable installations.

What cable do I need for a TV antenna?

Most TV antenna installations use RG6 75-ohm coaxial cable. Outdoor antennas should use outdoor-rated cable.

What connector does a TV coax cable use?

Most TV coax cables use F-type connectors. Some regional antenna systems may use IEC-style TV connectors.

Is coaxial cable better than HDMI for TV?

They are used for different things. Coaxial cable carries antenna, cable, or satellite RF signals. HDMI carries digital audio and video from a device to a TV.

For the full cable type and sizing overview, see the Coaxial Cable Guide. If your TV setup also involves a modem, router, or MoCA adapter, compare the networking side in coaxial cable vs Ethernet cable.
