Factors To Consider

Coaxial is popular because it is cheap and effective. 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, you will need to consider whether the drop in signal is worth it or if you are better off moving the antenna. If moving the antenna closer and still have the same signal quality is possible, you may find this a more practical solution. 

Manufacturer Reputation

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. 

Coaxial Antenna Extension Cables

Choosing the right antenna extension cable doesn’t need to be a complicated decision. Once you understand their role and the different options available to you it becomes easy to select one that will do the job you need it to. There is also a coaxial cable for gigabit internet.

The above list is a great starting point to help you find a cable by a reputable manufacturer and enjoy your video or audio device in a new position. You might need a BNC to RCA adapter. If you are thinking about a new set-up or changing your existing layout, it is worth picking up one of these antenna extension cables before you start.
