To transmit signals is accessible to your home and office, but for marine, that is off the grid in the sea; marine coaxial cables are in use.
Usually, in using marine coaxial cables, little or more signals are lost. But with our company’s coaxial cable, this loss of energy is made to a minimum, rendering you to a facility you have never experienced before.
You have arrived at the right page for the purchase of marine coaxial cables. To know more about marine coaxial cables, read further below.
Chapter 2: What is the marine coaxial cable?
Coaxial marine cable earns the name coaxial because unlike any other wires, it uses a single path for the transmission of signals. It is an efficient cable.
Coaxial marine cables are specially designed cables having a single core for transmission. The center is covered by a protective layer to act as a barrier for any minimum loss or interference.
Marine Coaxial cable is a single cable made up of three parts. Those three parts are as follows;
|The final layer of the cable.
|This layer acts as an armour of the cable.
|This layer protects the cable from wear and tear.
|This layer also protects the cable from the adverse effects of nature; heat, cold, pressure, humidity, etc.
|This layer makes the cable resistant to moisture
|This outer layer makes the cables resistant to fire, as well.
|This layer is also called the sheath of the cable
|This layer of aluminium which is responsible for the protection of signals during transmission.
|This layer acts as a barrier for the signals to prevent leaking.
|A further layer on demand can also be in the order, and this helps in adding an extra layer of protection.
|This addition of layer is in preference for more extended distance coverage.
Inner layer :
|This layer is the core of the cable.
|It is mostly copper or aluminium
|It may or may not be in a braid according to preference and customization.
|It is responsible for the transmission of signals.

Chapter 5: Are there any types of marine coaxial cables?
Yes, there are several types when it comes to coaxial cables. It depends on the length as well as the thickness of the wire. It depends on the measurement of the material being in use, as well.
Radio Guide also abbreviated as RG, and this is mainly seen with a number denoted the place to be in for use.
This type of cable is commercially in use.
Common types of RG include RG-6, RG-8, RG-58, and RG-59.
RG-6 is one of the most common of it all commercially
The material used in this is copper, braided.
RG -8 is in use for the transmission of radio signals.
RG -58 is in use for offshore business.
Chapter 5.1: What is RG6 coaxial cable?
- Radio Guide 6 or RG6 is the most abundantly used and commonly found coaxial cable
- With RG6, you can use it for the transmission of video as well as audio signals.
- The signals in RG6 coaxial cables occurs in transmission from source to the destination device.
- The connectors it will use are for the satellite dishes, the cable of television. For the antennas, this helps in the prevention of loss of signals.
- RG6 is an improved version, a replacement for radio guide 59. An improved and new version was made to overcome the loss and leakage of the signals.
- RG6 is a flexible cable in use since it is more durable and resistant to environmental effects.
Chapter 5.2: What is RG 214 coaxial cable?
- Radio Guide 214 is a coaxial cable that is in use when the transmission of signals with high frequency is to be in consideration.
- Its outer most protected layer is made up of PVC and consists of an out conductor of silver-plated, double.
- PVC helps in securing the cable from any abrasion of wear and tear.
- PVC is suitable for resistance towards moisture
- Its dielectric is of a material of polyethylene
- Polyethylene is a fantastic choice due to its cross-linking property.

- In Polyethylene, no loss occurs.
- RG 214 has excellent properties for shielding the transmission of power.
- You can use RG 214 for the transmission of data, in broadcasting, in radio transmission, other computer applications, etc.
Chapter 6: How does a marine coaxial cable work?
Marine Coaxial cables are a smart choice. This cable allows the transfer of data much efficiently and quickly. While in protection with the outer layer of armour.
The layerings and armour help ignore the electromagnetic induction or loss of signals.
The initial layer is called the dielectric layers. It is a poor conductor of electricity. This layer will act as an insulating material to protect the flow of transmission.
The tinned wire may also be used to make it more resistant to corrosion.
The dielectric layers also increase the distance between itself and the central core, adding up further insulation.
This dielectric may be PVC or a blend of plastic material, keeping the central core erect.
After this, another protecting material of copper and aluminium, or a mixture of the two is in cover.
Then the final layer, the outer most layer, which is visible to our eye. Collectively all these layers protect the wire.
Within these safely enveloped, protective layers, the electric waves pass through the wire without any interruptions or interference.
Chapter 7: How do you connect the coaxial marine cable?
It is necessary to connect the marine coaxial cable because a single wire would not suffice.
With the increment in length, connectors are used to minimize the loss of power, working efficiently.
Our company advises to connect the marine coaxial cable in the following manner;
Be prepared and purchase the connectors when placing the order for the cable.
There are two types of connectors; the male connector has teeth and is attached to the ends of the cable.
The teeth help in holding the cable with firmness.
The female connectors are also known as barrel connector.
The female connectors are hard to find and are preferred to be in use in rest parts of the cable.
In an ultra high-frequency connection, use electrical tape to secure the cable with extra protection.
Chapter 8: What is the purpose of 50Ω and 75Ω coaxial cable?
- Where there is a direct flow of current, there is resistance. Where there is resistance, there is ohm, that is the unit of resistance.
- The use of dielectric characterizes the value of the ohm.
- It was previously in believing that an ohm of 30 would suffice the cable to handle the power. And 77 ohms would account for the lesser loss of signals being in transmission from one place to another.
- With the variation in the dielectric, it is believed to say that 50 ohms would be sufficient enough to offer to handle high power with minimal loss of signals.
- To hit two sparrows with one arrow in a budget, choose 50 ohms.
- For power handling of high watts, that is 100 watts, or more 50Ω coaxial cable is in use.
- 50Ω coaxial cable is in use for transmission of signals.
- 50Ω coaxial cable is an ideal selection for transmitter function.
- However, not everywhere, power handling is in need or a primary purpose.
- However, tempting it may be, but 50 ohm is not appropriate for places where power handling is not needed.
- 75Ω coaxial cables are best to be in use for areas where the minimum loss of power is the goal to be achieved.
- 75-ohm coaxial cables’ only goal is to transmit a good strength of the signal with minimum or no damage.
- 75Ω results in a low attenuation, ideal for any cable.
- 75Ω coaxial cables are primarily used in the transmission of audio, video, or data from one place to another with greater distance.
- 75Ω coaxial cables are an ideal use for receiving
Chapter 9: Why use marine coaxial cable and not satellite communication?
- Before the introduction of cables in the modern era, communication was made possible through satellite or radio signal transmission.
- This source of communication was not a reliable source because it could quickly be interrupted.
- If a person tunes the right frequency, all your data could fall in the wrong hands and invade your privacy or confidential matters.
- Marine coaxial cable comes handy in this case because the wire is protected in several layers from invasions and maintains a person’s privacy.
- Marine coaxial cable is applicable anywhere with easy installation.
Chapter 10: What is the difference between the coaxial cable and optic fibre?
Both carry signals with high precision, then what is the significant difference and which one to be in use? The questions answers are below;
- Variation in material
Fibre optics use equipment of plastic and glass. In contrast, coaxial cables use material of plastic PVC, metal wire, and braided insulation of metal as well.
- Difference in rate
Optic fibre is more costly as compared to coaxial cable. Coaxial cables appear to be pocket-friendly, performing the job well.
- Difference in flexibility
Marine coaxial cables are easily bent, unaffected. It can be bend in any direction. Whereas optic fibre is not bending friendly and easily gets affected.
- Difference in installation
Coaxial cable is a friendly user cable. It is easy to install and anywhere. Whereas optic fibre is selective in this matter and is a little complex to be installed.
- Difference in weight
Optical fibre is light in weight, having a small diameter. But marine coaxial, on the contrary, has a larger diameter with a heavyweight.
- Difference in transmission
The optical fibre mode of communication is light, whereas coaxial cables method of transmission is electricity.0
- Difference in maintenance
The optical fibre may be efficient and pricey but comes along with higher support. Since it uses light as a mode of transmission, single damage can affect the cable severely.
Optical fibre is delicate and can be easily damaged, whereas coaxial cable is not.
Now you know the reasons behind choosing marine coaxial cable.
Chapter 11: Does marine coaxial cable has a disadvantage?
The marine coaxial cable is cheap, easy to handle, and easily installed. But its weight and diameter are overlooked with the price and precision it offers.
Marine coaxial cable only disadvantage is its relation to increment in length/ distance.
As the length increases, the sensitivity or potential or signal loss increases.
Our company has efficiently overcome this disadvantage by installing a repeater when needed.
Chapter 12: What are the advantages of the marine coaxial cable?
Marine coaxial cable is not only cheap and easy to install, but it also has several other advantages. The advantages need to be highlighted to consider the selection of such wires.
The advantages are listed as follows;
- It is a broadband system wide enough to accommodate not one channel but more in number.
- The number of channels does not affect its frequency.
- It is used to provide a wide range of signals.
- It has a substantial capacitance.
- The error is minimized in coaxial marine cables because it consists of protective layering, which blocks the electromagnetic induction and leakage of signals.
- It consists of connectors for the prevention of leakages and can occupy a larger span.
- It reduces noise and cross-talks by the provision of space in the amplifiers.
Chapter 13: What are the three losses to be considered in the marine coaxial cable?
- Resistive loss
- Relative loss is also known as joules loss, i.e., loss due to heat.
- When heat is in emission the focus of power is a diversion which results in loss
- Resistive loss happens due to the selection of a conducting material and the heat produced in it as the current passes through it.
- This loss is made correct by our company using more than one strand as a conductor to minimize the friction.
- Dielectric loss
- Dielectric loss in a coaxial cable is due to the increase in heat.
- The generation of heat takes place when current passes through the cable.
- Radiated loss
- Radiated loss is a loss when the outer surface area is more, the braiding done is poor-Lesser the area, lesser the loss.
- Radiated loss is a type of injury that is lesser than the above two mentioned losses in comparison.
Chapter 14: Is marine coaxial cable harmful?
Our eco-system is in depletion. The method to sustain it is to be in consideration in every field of life, cables being one of them.
- Marine coaxial cable is friendly to the environment due to its low emission of smoke.
- Marine coaxial cables are free from halogens, and this is necessary because when halogens burn it releases toxic gases that are harmful to the atmosphere, let alone for humans.
- Marine coaxial cables are resistant to fire; hence, it controls the fire rather than spread it.
Chapter 15: Where is coaxial marine cable used?
Marine coaxial cables can be efficient in use in the areas which are as follows;
- Maine coaxial cables are in use in telecommunication services.
- It is in use for the transmission of data, video, pictures, documents, etc.
- The transmitter of radio and receivers can be in link with the internet.
Chapter 16: Can Marine coaxial cable be used in radio for audio transmission?
Marine coaxial cables do not serve the purpose of broadband but serve the purpose of transmission of audio signals
When connected to a radio, and its transmitter is directly in link to the antennas, it can easily transmit signals of the audio.
Chapter 17: What are marine coaxial cable important parameters
A cable is made up of its parameters, which governs its functioning and performance. The parameters are to be in proper consideration.
The parameters that make up the marine coaxial cables include;
- The physical parameter of length
- The dia of the cable; inner and outer.
- Choose of insulating material for better resistance
- Pre calculations of wire for voltage, attenuation per unit length, strength, permeability, etc.
- The capacity of shunt, series inductance, and series resistance. Shunt conductance per unit length.
- The type of dielectric.
- The type of conductor.
Chapter 18: What is the standing wave ratio meter?
The standing wave ratio meter or SWR is a tool to find the compatibility between the load and the line of transmission, if it is a match or not.
You can test your marine coaxial cable with the help of a standing wave ratio meter.
You can identify the minimum and maximum ratio, a fit for your work, good to go coaxial cable will give a reading of 2, 3, or between the two ohms.
If the reading ratio is lower or higher, it will indicate a mismatch.
The reasons that may affect the reading ratio are as follows,
- Use of wrong resistance
- Use of improper insulation
- Connectors not installed properly
- Not adequate, the constant spacing between the protective layers and the conductor core.
- When the bending radius is not in consideration before manufacturing, any sharp and sudden bend will affect the working of the cable, ultimately the ratio.
