We can't deny the vast role of coaxial cable in our life. Can you imagine your life without a Television or a Speaker? These devices aren't capable without the use of a Coaxial cable. In 1880 English engineer Oliver Heaviside invented coaxial cable.
Coaxial cable is a data cable used to send radio frequency signals. Let's discuss the coaxial cable and what is the coaxial cable used for in detail.
Conclusion
Coaxial cable is the backbone of the telecom sector and many areas of our life. We can't imagine our life without coax cable. Today I tried to answer some common questions about coax cable. I hope it will help you to get what are you looking for.
Classifications of coaxial cable
Four main classifications of coaxial cable depend upon the amount of resistance. 50 ohms, 60 ohms, 75 ohms, and 93 ohms are the resistance values in a particular Cable. The most commonly used cables are 50 OHMS and 75 OHMS.
what are the types of coaxial cable?
- Hard line coaxial cable
- Flexible coaxial cable
- Semi-rigid coaxial cable
- Formable coaxial cable
- Rigid coaxial cable
- Twin axial cable
- Triaxial cable
Another point of differentiation of coax cable is RG. RG stands for radio grade. below are the most common types of coaxial cable
- RG-6
- RG-11
- RG-59
- RG-58
- RG-62
- RG-75
The most common question I have seen many times.
Can coaxial cable be used for speaker wire?
Yes! You can use the coaxial cable as a speaker wire, but it may not be the best and most efficient way to use it as a speaker cable. It requires an RCA connector instead of a standard F connector to use a coaxial cable as a speaker wire.
Another reason to avoid coaxial cable as a speaker connector is your amplifier doesn't work smoothly with the coax.
It ultimately affects your audio quality and also possibly harms your speaker.
Use a coaxial cable as a speaker cable only when no other option is available.
Is coaxial cable good for audio?
Many times people get confused when choosing cable for audio. You have two choices, Optical cable, and coaxial cable. Those who want better audio quality must prefer coaxial cable. Coaxial cable can handle broader bandwidth than optical fiber. Because of having higher bandwidth, it supports higher quality audio. So, we can say that a coaxial cable is a better choice for audio.
Is coaxial better than RCA?
Digital coax is a digital audio connection. RCA is the analog audio connection.
Coaxial cable is made out of coax with better shielding. Due to better shielding, the transmission of the signal is better.
Because of lesser electromagnetic interference. So, yes! We can conclude that coaxial is better than RCA.
How far can coaxial cable run?
Radio Grade type decides how long the coax cable can run.
RG59 can travels the shortest distance while RG11 can run the longest distance. for example, if RG6 can go up to 1000 feet of maximum distance RG11 goes 1500 feet and RG59 goes 750 feet for the same kind of application. Though this distance depends on many factors. Few other types are RG174, RG213, RG8 X, and so on RG6 is used for shorter distance signal transmission. RG11 is used for wide bandwidth transmission at longer distance.
What are the differences between RG6, RG11, and RG59
- RG6 coaxial cables are used for the applications like cable branches to transmit camera data and connect Indoor Television Equipment.
- RG11 is used for observing camera data, cable TV, etc
- RG59 is used for CCTV installations
Does the length of coax cable matter?
Yes! naturally, the more the length of coaxial cable you use, the more signal loss you have to face. few factors like loss due to resistance and dielectric loss also affects the signal transmission.
What are the advantages and disadvantages of coaxial cable?
Of course, coaxial cable has many advantages. This is the reason they are widely used for data transmission. Which are they?
Pros
- affordable
- easily available
- durable and high resistivity to the physical damage
- efficient transmission and high transmission capacity
- Supports the high bandwidth signal transmission compared to other types of cable
Cons
- maintenance cost
- bulky
- you need to ground it to prevent interference
What is the biggest drawback of coaxial cable?
The biggest drawback of coaxial cable is it affects the entire network even if a single cable is fail.
Another main disadvantage of coaxial cable is signal loss. that's why it's not recommended to use a coaxial cable for long distances.
How do I know what coax I have?
You can identify cable type by knowing the radio grade (RG) labeled on the cable. This RG is followed by a number like RG6. RG11, RG59, and so on.
Which is better RG6 or RG11?
RG6 has more attenuation compared to RG11. Less thickness of RG6 causes more signal loss, but that's the one side of the coin. RG6 is affordable compared to RG11. It is more flexible too. If you want less attenuation rate for the specific application, RG11 is recommonded. For longer distances, RG11 is suitable due to less attenuation.
What is 75 ohm coaxial cable used for?
75 Ohm cable is used for commercial as well as residential use. It can transmit signals up to 50 Feet. 75-ohm cable is used for
- Satellite and Cable boxes
- High Def TV signals
- Transmission of video signals
- digital audio signals
- broadband internet data signals
What does coaxial mean in speakers design?
The coaxial speaker is a two-way speaker which accommodates less space. It has tweeter and crossover. The crossover directs sound to the correct driver which improved sound quality. The traditional single cone speaker is replaced by a coaxial speaker which is more flexible for installation and takes less space with improved audio quality.
What's the difference between coaxial and component speakers?
I have seen a debate many times about which type of speaker is better car speaker, a Coaxial, or a component speaker. The coaxial speaker is affordable compared to the component speaker. When we checked the sound quality, the component speaker was found better.
A coaxial speaker is also known as a full range speaker which has more than one driver that reproduces a range of audio frequencies.
The component speaker has only one driver. So, they are designed to deliver better highs, lows, and mids. audiophiles mainly use this type of sound system in their car. component speakers are more expensive compared to coaxial speakers and also deliver better sound quality.
