What is the Different Classification of Marine Coaxial Cable?

Marine coaxial cables are classified based on the RG protocol with a number after the RG.

The most common classifications include RG6, RG 11, RG 58, RG 59, RG 213, and RG 214.

What does RG Mean in Marine Coaxial Cable?

RG is an initiative that stands for Radio Guide.

RG often has a number that comes after it that you can use to identify the type of marine coaxial cable.

For instance, RG 30 means that the marine coaxial cable is number 30 in the production line.

The number does not necessarily mean there is a relationship between the cable and the number.

What is RG6 Coaxial Cable Used For?

 RG6 Cable

 RG6 Cable

RG6 coaxial cable is one of the most common cables in use.

You can use it for the transmission of audio and video signals to different devices such as television sets.

It carries the signals from a transmitter straight to the displaying device.

This includes connections of aerial antennas, cable televisions and satellite dishes.

RG6 is also common because it comes as a replacement for RG59 which was prone to signal leakages.

Apart from that, you can use the RG6 in different applications as it is more durable against external environmental interferences.

How does RG11 and RG59 Marine Coaxial Cables Compare?

RG11 Cable

 RG11 Cable

RG59 Cable

RG59 Cable

You can use the RG 11 coaxial cables for wide broadband with a transmission distance that is wide apart.

It is a common coaxial cable in the transmission of camera data and cable televisions among others.

Also, it can transmit signals to a wider distance because it has lower attenuation levels thus making it more expensive.

Apart from the high cost, RG 11 is not flexible thus an inability to bend at different angles.

RG 59 is a flexible, intertwined multi-small fiber cable that you can use in the transmission of analog camera data.

It is the best coaxial cable for low frequency and low bandwidth transmissions such as CCTV installations.

What is RG214 Coaxial Cable?

RG214 Cable

RG214 Cable

The RG214 is a type of cable that you can use for transmission of high-frequency signals.

It consists of stranded, silver-plated inner conductors, polyethylene dielectric, PVC Jacket and double silver plated outer conductors.

The jacket is responsible for protecting internal features from damage by external environmental factors such as moisture and abrasion.

It has perfect shielding properties that give the cable consistent and excellent current.

You can use it in data transmission, telecommunication, broadcast, radio frequency transmission, and computer applications.

How do you Test Marine Coaxial Cable?

You can test the marine coaxial cable using special equipment such as the SWR (standing wave ratio) meter.

The SWR meter will give you readings that will indicate that the marine coaxial cable is fine or not.

A good coaxial cable will give you a reading of between 2 to 3 ohms.

Anything lower or higher than that signals that there is a problem with the marine coaxial cable.

What is RF Coaxial Cable Used For?

RF coaxial cables are one of the types of coaxial cables that you can use in the transfer of radio frequencies.

You can use the RF cable in the transmission of communication signals while at sea.

You can identify through the connectors at the end of the coaxial cable.

It has a small pin that you will plug into the RF input of the communication device.

You can also use it on television and internet connections.

How Does Marine Coaxial Cable Work?

A marine coaxial cable has different structural parts that perform different functions.

Once the connection is complete and the transmitter begins to transmit signals, the following happens:

  • The inner core which is basically the conductor carries the signals.
  • The shield which consists of a combination of braid and foil reduce signal degradation while minimizing electromagnetic interference.

The greater the shielding coverage, the better the transmission of the signals.

  • Consider maintaining the space between the shield and the core for better signal transmission.

You can achieve it by using a dielectric insulator between the shield and the core.

Changes in spacing will lead to a reflection of the radio signals back to the source.

Which Connectors are Used with Marine Coaxial Cable?

Coaxial cable connectors are devices that you can use to connect coaxial cables to other devices.

They have special designs that will maintain the shielding properties of the cables.

Some of the coaxial cable connectors include:

How do you Splice Marine Coaxial Cable?

You should consider going through the following steps to splice marine coaxial cables.

First, you need to have the coaxial cable connectors that will join one cable to the other.

Join one end of the coaxial cable to the male connector which has teeth to hold the cable firmly.

You can either use a barrel connector or a female to connect the other pieces of the wire.

You should consider using the barrel connectors because the female connectors are often difficult to find and install.

In case of a UHF connection, ensure that you use electrical tape to wrap and provide extra protection.

Can You Use Marine Coaxial Cable for Audio?

Yes, you can use marine coaxial cables for audio.

Marine coaxial cables are basically fed lines that connect radio receivers and transmitters to antennas for audio signal transmission.

What are the Advantages of Marine Coaxial Cable?

The advantages of marine coaxial cables include:

  • It has a wide broadband system with a sufficient frequency range that supports multiple channels and allows for maximum throughput.
  • It has a greater channel capacity that can accommodate numerous channels with substantial capacity.
  • Coaxial cables provide greater bandwidth for the system and also for every channel that supports wider range of services.
  • It has minimal errors because the structure has faraday shields that prevent signal leakage.
  • It has more spacing provisions between the amplifiers to reduce cross talks and noise.

Is Marine Coaxial Cable Better than Optical Marine Cable?

The digital coaxial cable is the best optical marine cable because it has a wider frequency bandwidth.

Optical marine cable uses the fiber optics cable that transmits digital audio bitstreams using light pulses.

Coaxial cable depends on the RCA connectors that can handle wider frequency bandwidths of the digital audio bitstream.

Implying that the marine coaxial cable is better than the optical marine cable in terms of digital audio bitstream.

What are the Important Marine Coaxial Cable Parameters?

Coaxial cables have different cable parameters that enable it to perform its functions properly.

The coaxial cable parameters you should consider include:

Parts of coaxial cable

  • Physical parameters such as length, the inner and outer diameter of the cable.

You should also consider the dielectric constant and magnetic permeability of the insulators.

  • Fundamental electrical parameters such as shunt capacitance, series inductance, series resistance, and shunt conductance per unit length.
  • Derived electrical parameters such as characteristic impedance in ohms, attenuation per unit length, propagation velocity, peak voltage, and mode band.
  • Choice of impedance

Is Marine Coaxial Cable Fire Resistant?

Yes, marine coaxial cables are fire resistant allowing you to transmit information in case of a fire breakout.

What is the Best Coax Cable for Marine VHF?

The best coax cable for marine VHF can either be:

  • 50 ohms RG-58CU coax cable
  • 50 ohms RG8X coax cable
  • 50 ohms RG213 coax cable

You should consider using the largest coaxial cable as you can for marine VHF to reduce the loss of signals.


Almost all the VHF cables start with a transmission power of about 25 watts.

At the beginning point of signal transmission, the signal usually begins to lose strength.

A bigger coaxial cable will minimize the loss of signals between the antenna and the radio thus increasing antenna power.

What Makes Marine Coaxial Cable Structure?

The structure of a coaxial cable consists of:

  • Inner conductors copper conductors which transit the signals
  • Inner dielectric insulator or conducting Shield which protects the inner conductors from leaking signals.
  • Jacket woven copper shield which offers further protection from signal leakages
  • The outer plastic sheath or insulating layers which protect the inner material from external environmental effects such as water and abrasion.
