The antenna extension cable is also known as coaxial cable. In fact, this type of cable is used across the globe within the telecommunications industry. It is the main cable between your rooftop aerial and your TV box. Coaxial cable is also used to connect your satellite dish to your receiver and it is capable of transmitting audio and video.
Although the modern digital age is increasingly supportive of wireless and fiber optic cables, coaxial cable is well shielded and reliable. It is also significantly cheaper than fiber optic.
There are three common sizes of coaxial cable, RG-6, RG-11, and RG-59. The RG simply stands for Radio Guide, you may also hear them referred to as RF cables, standing for Radio Frequency. The number simply refers to the diameter of the cable.
In most cases RG-6 is satisfactory but for longer runs or to improve signal quality RG-11 may be used. You should also note that RG cables generally use F-type connectors. These can be screw fitting, crimp, or even compression.
Composition Of An Antenna Extension Cable
A coaxial cable has two conductors. The inner one runs through the center of the cable and is wrapped in a conductive shielding. The inner core is usually copper-clad steel. After the insulation layer, there will be four layers of outer conductors. These are all designed to shield the electrical signal and eliminate noise.
To finish, the cable has a UV stable outer jacket that increases the core protection. This is all designed to maximize the signal quality and your experience. Of course, fiber optic cable is capable of carrying stronger signals for further.
Factors To Consider When Choosing An Antenna Extension Cable
Coaxial is popular because it is cheap and effective. In many cases, it is the right answer for your home. It is extremely easy to extend a coaxial cable and the cables are surprisingly durable.
However, before you commit to one of the following antenna extension cables, there are several things you should be aware of and consider.
Length Of Extension
A coaxial cable will lose a little of the signal between the antenna and the receiver box. While a small drop makes no discernable difference, when the drop is too big you will notice a drop in image and audio quality.
In general, you will lose about twenty decibels per one hundred feet of cable. If you have a long extension to do you will need to consider whether the drop in signal is worth it or if you are better moving the antenna.
If it is possible to move the antenna closer and still have the same quality of signal you may find this a more practical solution.
When you are choosing any product one of the most important considerations is who has made the product and who is supplying it. When you are choosing an antenna extension cable you should know who the manufacturer is and trust them. If you have heard of them already then you should have an opinion regarding how good, or bad, they are.
But, if you have never heard of them, you will need to investigate a little. That means checking with family, friends, and work colleagues to find out if they have any experience with them and what they think of the business.
If this isn’t helpful then take a look at social media and online forums. You will find plenty of honest opinions to help you make your mind up.
It is always a good idea to look at several options before you commit to buying one. This will help you to establish an average price. With an average price in mind, you will be able to decide if the price of the antenna extension cable you intend to buy is reasonable. Don’t forget, if the price is too cheap it can suggest poor quality. But, too high and you need to question what you are getting for the additional funds.
