Coaxial Cable Manufacturer for CCTV, RF and Video Systems

Coaxial Cable provides controlled-impedance signal transmission for CCTV, broadcast, antenna, RF, video and communication systems. ETK Kablo manufactures a broad range of RG-series coaxial cables including RG-6, RG-8, RG-11, RG-58, RG-59, RG-213 and RG-216 constructions for different impedance, conductor, shielding and installation requirements.

The ETK Kablo portfolio includes solid and stranded copper conductors, tinned copper conductor options, solid or physically foamed polyethylene dielectric systems and several metallic-screen architectures. Depending on the exact RG construction, screening can use copper braid, tinned copper braid, aluminum braid, Al/PET foil or combinations of multiple screening layers.

Selecting the correct coaxial cable requires more than choosing an RG number. Characteristic impedance, attenuation, capacitance, conductor construction, dielectric type, screen architecture, cable diameter, operating frequency and installation environment should all form part of the specification.

What Is a Coaxial Cable?

A coaxial cable is a signal cable built around a central conductor surrounded concentrically by a dielectric insulation layer and one or more metallic screens.

The outer conductor or screen surrounds the inner conductor and helps control the electromagnetic field inside the cable. This geometry allows coaxial cable to maintain defined impedance while limiting external electromagnetic interference.

Coaxial cables are widely used for radio-frequency, video, antenna and broadband signal transmission where controlled electrical characteristics are important.

How Coaxial Cable Is Constructed

Layer	Main Function
Inner Conductor	Carries the electrical signal
Dielectric	Maintains electrical separation and influences impedance, capacitance and propagation velocity
Metallic Screen	Provides the outer conductive path and electromagnetic shielding
Outer Jacket	Provides environmental and mechanical protection according to the exact construction

Small changes in conductor diameter, dielectric geometry or screen construction can significantly affect the electrical behavior of a coaxial cable. For this reason, cables with similar outside dimensions should not automatically be treated as interchangeable.

ETK Kablo Coaxial Cable Range

RG Family	General Construction Direction	Common Project Intent
RG-6	Foil and braid screened designs, including Trishield variants	Video, CATV, satellite and compatible 75-ohm systems
RG-59	Several solid-conductor and screen variants	CCTV and video signal transmission
RG-11	Larger-diameter coaxial constructions	Longer signal routes according to the exact impedance specification
RG-58	Compact RF coaxial constructions	50-ohm RF and communication applications
RG-8	Larger 50-ohm RF coaxial construction	Radio, antenna and RF connections
RG-213	Stranded-copper 50-ohm coaxial construction	RF and radio-frequency signal applications
RG-216	Double-braid screened coaxial construction	Applications requiring its specified 75-ohm electrical architecture

The exact RG product datasheet should determine final application suitability because impedance and electrical characteristics can vary between individual RG variants.

50 Ohm vs 75 Ohm Coaxial Cable

Characteristic impedance is one of the most important parameters when selecting coaxial cable.

Many RF and radio systems use approximately 50-ohm coaxial cable, while many video, broadcast, CATV and CCTV systems use approximately 75-ohm coaxial cable.

Nominal Impedance	Typical Application Direction	ETK Examples
50 Ω	RF, radio, antenna and equipment interconnection	RG-58C/U, RG-8/U, RG-213
75 Ω	Video, CCTV and compatible broadcast systems	RG-6/U-4, RG-59/U, RG-216

The system impedance and cable impedance should match. Substituting a 50-ohm cable for a specified 75-ohm system, or vice versa, can create reflections and degrade signal performance.

ETK Kablo also offers RG constructions with impedance values outside these two simplified nominal groups. Therefore, buyers should verify the exact product value rather than assuming impedance solely from the RG family name.

RG-6 Coaxial Cable

RG-6 coaxial cable is widely associated with video, broadband, CATV and satellite signal distribution.

The ETK Kablo RG-6/U-4 construction uses a 1.0 mm solid copper center conductor, physically foamed polyethylene dielectric, an Al/PET foil screen and aluminum braiding.

The characteristic impedance is 75 ohms, while the physically foamed dielectric supports a relatively high signal-propagation velocity.

ETK Kablo also manufactures additional RG-6/U-4, RG-6/U-6 and Trishield versions for different shielding requirements.

RG-6 Trishield Coaxial Cable

ETK Kablo's portfolio includes dedicated RG-6 Trishield products.

Trishield construction adds additional metallic screening compared with a simpler coaxial architecture. The purpose is to improve isolation against external electromagnetic interference and unwanted signal ingress or egress.

The exact shield layers and electrical data should be checked from the applicable Trishield product datasheet.

RG-59 Coaxial Cable

RG-59 coaxial cable remains strongly associated with video and CCTV signal transmission.

The ETK Kablo RG-59/U construction uses a 0.83 mm solid copper conductor, physically foamed polyethylene insulation, Al/PET foil and tinned copper braiding.

The construction has a 75-ohm characteristic impedance.

The wider RG-59 portfolio also includes RG-59/U-4, RG-59/U-6 and RG-59B/U-2 variants, allowing buyers to select according to the exact conductor and shielding specification.

RG-6 vs RG-59 Coaxial Cable

RG-6 and RG-59 can both appear in 75-ohm video systems, but their physical and electrical constructions differ.

Characteristic	RG-6	RG-59
General Cable Size	Typically larger	Typically more compact
Common Application Direction	CATV, satellite, broadband and video	CCTV and video
Attenuation	Should be checked by exact frequency and product	Should be checked by exact frequency and product
Impedance	75 Ω on ETK RG-6/U-4	75 Ω on ETK RG-59/U

Neither RG designation should be selected from application name alone. Cable length, frequency, attenuation and connector requirements should determine the correct product.

RG-11 Coaxial Cable

ETK Kablo manufactures several RG-11 constructions including RG-11/U-4, RG-11/U-6 and RG-11A/U.

These are physically larger coaxial cables than many RG-6 or RG-59 constructions and can be relevant where the electrical characteristics of the exact RG-11 version match a longer or more demanding signal route.

However, buyers should not assume that every ETK RG-11 product is automatically a standard 75-ohm CATV cable.

ETK Kablo technical data specify different characteristic-impedance values across its RG-11 variants. Therefore, the exact product code must form part of the RFQ.

RG-58 Coaxial Cable

RG-58 is a compact coaxial family commonly associated with 50-ohm RF and communication systems.

The ETK Kablo RG-58C/U construction uses a 19 x 0.18 mm stranded tinned copper conductor, solid polyethylene dielectric and tinned copper braid.

The characteristic impedance for RG-58C/U is 50 ohms.

The portfolio also includes RG-58/U-4, providing another construction option within the RG-58 family.

RG-8 Coaxial Cable

RG-8/U provides a larger 50-ohm RF coaxial construction.

The ETK Kablo RG-8/U uses a stranded copper inner conductor, solid polyethylene insulation and annealed copper-wire braiding.

Its datasheet specifies a characteristic impedance of 50 ohms and an operating-temperature range from -40°C to +70°C.

ETK Kablo also manufactures RG-8A/U as a separate RG-8-family construction.

RG-213 Coaxial Cable

RG-213 is another 50-ohm RF coaxial cable in the ETK Kablo portfolio.

The construction uses a 7 x 0.70 mm stranded copper conductor, solid polyethylene dielectric and electrolytic copper braid.

Its characteristic impedance is 50 ohms.

RG-213 can suit compatible RF, radio and equipment interconnection applications where its cable diameter, conductor construction and electrical characteristics match the system design.

RG-216 Coaxial Cable

RG-216 uses a stranded tinned copper conductor together with solid polyethylene insulation and two electrolytic copper-braid screens.

The ETK Kablo RG-216 construction has a 75-ohm characteristic impedance.

The double-braid screen distinguishes RG-216 from simpler single-braid designs and provides an option for projects requiring its specific electrical and shielding architecture.

Solid vs Stranded Coaxial Cable Conductor

ETK Kablo uses both solid and stranded center conductors across its coaxial portfolio.

A solid conductor can provide a stable geometry for fixed installation, while a stranded conductor offers a different flexibility profile.

Examples from the range include solid copper in RG-6/U-4 and RG-59/U, stranded tinned copper in RG-58C/U and RG-216, and stranded copper in RG-8/U and RG-213.

The center conductor should therefore be specified by the exact product rather than assuming one conductor type for every RG cable.

Bare Copper vs Tinned Copper Coaxial Cable

ETK Kablo also uses different copper conductor finishes according to the RG construction.

Tinned copper adds a metallic coating to the copper strands and appears in products such as RG-58C/U and RG-216.

Other products use bare electrolytic copper.

The conductor material can influence resistance, termination and environmental behavior, so procurement specifications should identify the exact conductor requirement where it matters.

Foil and Braid Screening in Coaxial Cable

Coaxial cable already uses its outer conductor as part of the signal-transmission geometry, but different products use different screen architectures.

ETK Kablo constructions include:

• Copper braid
• Tinned copper braid
• Aluminum braid
• Al/PET foil
• Foil + braid combinations
• Double-braid constructions
• Trishield variants

Additional screening can improve immunity against external electromagnetic interference, but the required architecture should follow the actual system and installation environment.

Foamed PE vs Solid PE Dielectric

Polyethylene dielectric construction directly affects important coaxial parameters such as capacitance and propagation velocity.

Some ETK Kablo products, including RG-6/U-4 and RG-59/U, use physically foamed polyethylene.

Other products such as RG-58C/U, RG-8/U, RG-213 and RG-216 use solid polyethylene.

This is one reason electrical values vary significantly between RG products even when they belong to the same broad coaxial category.

Coaxial Cable Capacitance

Capacitance is an important coaxial cable parameter and varies substantially between constructions.

For example, ETK Kablo technical data specify values around 53 pF/m for RG-6/U-4, approximately 75 pF/m for RG-59/U, approximately 100 pF/m for RG-213 and approximately 101 pF/m for RG-58C/U.

One common capacitance range should therefore not be applied to the complete coaxial portfolio.

Coaxial Cable Propagation Velocity

Propagation velocity describes how quickly an electrical signal travels through the cable relative to the speed of light.

Dielectric construction strongly influences this parameter.

ETK Kablo examples include approximately 0.84 for physically foamed PE designs such as RG-6/U-4 and approximately 0.66 for several solid-PE constructions.

The exact product value should be used for applications where signal timing or cable length is technically important.

Coaxial Cable for CCTV Systems

Coaxial cable remains widely used for analogue and compatible HD-over-coax video surveillance systems.

RG-59 and compatible 75-ohm constructions are particularly relevant to CCTV video links between cameras, recorders and distribution equipment.

ETK Kablo also has a separate CCTV Cable category containing composite surveillance constructions. Therefore, buyers requiring combined video and power conductors should evaluate that category rather than assuming that a standalone RG coaxial cable includes power conductors.

Coaxial Cable for CATV and Television

CATV and television distribution systems commonly use controlled 75-ohm coaxial cable.

RG-6 constructions can provide a suitable architecture for compatible broadband, television and satellite distribution systems.

Longer runs may require a different cable size or attenuation profile, so designers should compare attenuation at the actual operating frequency rather than selecting cable solely by RG number.

Coaxial Cable for Satellite Systems

Satellite distribution uses high-frequency signals and therefore places significant importance on attenuation, impedance and screening.

RG-6 and other compatible 75-ohm constructions can serve satellite signal routes where their documented frequency and attenuation performance meet the equipment requirement.

Connector selection and installation workmanship also affect the complete RF path.

50 Ohm Coaxial Cable for RF Systems

RF transmitters, receivers, antennas and test equipment frequently use 50-ohm interfaces.

ETK Kablo's portfolio includes 50-ohm constructions such as RG-58C/U, RG-8/U and RG-213.

The correct choice depends on frequency, attenuation, cable diameter, flexibility, connector system and required power handling.

Coaxial Cable for Antenna Systems

Antenna feeder and equipment-interconnection applications require the cable impedance to match the connected RF system.

50-ohm RG constructions can be relevant to radio-frequency equipment, while other systems can use different impedance architectures.

For antenna projects, the RFQ should specify operating frequency and system impedance rather than simply requesting an antenna cable.

Coaxial Cable for Broadcast and Video

Broadcast and professional video infrastructure depends on predictable impedance and low signal degradation.

75-ohm coaxial constructions are widely used for compatible video architectures, while the exact cable should be selected according to frequency, attenuation and connector requirements.

ETK Kablo's RG-6, RG-59 and selected other 75-ohm constructions provide several physical and shielding options for such systems.

Coaxial Cable vs CCTV Cable

Coaxial Cable and CCTV Cable should not automatically be treated as the same product category.

Characteristic	Coaxial Cable	CCTV Cable
Main Construction	Standalone coaxial signal cable	Can combine video coax with additional power or control elements according to design
Main Purpose	RF, video or broadband signal transmission	Surveillance-system connectivity
Typical Selection	RG code, impedance and electrical performance	Camera-system architecture and required combined functions

Where the camera installation requires only a coaxial video link, an RG product can be appropriate. Where video and power need to travel within one composite cable, the dedicated CCTV range should be evaluated.

Coaxial Cable vs Twisted Pair Data Cable

Coaxial and twisted-pair data cables use fundamentally different transmission geometries.

Coaxial cable uses a central conductor surrounded by a concentric outer conductor, while Ethernet data cable uses balanced twisted pairs.

Modern LAN networks normally use Cat 5e, Cat 6, Cat 6A or higher balanced twisted-pair cabling rather than RG coaxial cable.

Coaxial cable remains important where the equipment interface specifically requires RF, video or coaxial transmission.

Outer Jacket Options

ETK Kablo offers different jacket-material options according to the exact RG construction.

Available product variants can include PVC, halogen-free and polyethylene outer-jacket directions.

The required jacket should follow the installation environment, fire strategy and applicable product documentation.

Outdoor or UV-exposed installation should only use a construction whose exact datasheet confirms suitability for that environment.

Halogen-Free Coaxial Cable

Selected ETK Kablo coaxial constructions are available with halogen-free outer-jacket options.

Applicable product documentation includes tests such as IEC 61034-2 for smoke density and IEC 60754-1/-2 for halogen and corrosive-gas characteristics.

These tests apply according to the exact jacket construction. They should not automatically be assigned to every PVC or PE version within the complete category.

Coaxial Cable Operating Temperature

Temperature ratings should be taken from the selected RG product datasheet.

Several ETK Kablo products, including RG-6/U-4, RG-58C/U, RG-8/U, RG-213 and RG-216, have operating-temperature ranges of -40°C to +70°C.

A single category-level temperature rating should therefore not replace the exact product specification.

Coaxial Cable Standards

Manufacturing standards vary according to the RG construction.

Several ETK Kablo RG products, including RG-58C/U, RG-8/U, RG-213 and RG-216, reference MIL-C-17 in their product documentation.

Other coaxial applications can reference different international or project-specific requirements.

Procurement teams should therefore specify the required standard and verify it against the exact ETK Kablo product datasheet rather than applying one common standard to every RG cable.

A complete coaxial-cable RFQ should identify the electrical and physical requirements rather than requesting only a generic coax cable.
