[Explained] Can You Get 1080p Through Coaxial?

You may have heard the term that coaxial cable can transmit high-definition resolution. So, can you get 1080p through coaxial? This is a common question that has been asked by many people who are eager to experience the best possible picture quality.

Coaxial cables are commonly used for transmitting analog or digital signals, including cable TV, satellite TV, and older video formats. As they have limited bandwidth, they are not capable of carrying the higher data rates required for full HD or 1080p resolution.

In this article, we’ll explain what resolutions coaxial cables are capable of transmitting and provide the proper answer to whether you can get 1080p over coaxial.

Capabilities of Coaxial Cables

Although coaxial cables can transmit audio and video signals, they were primarily designed for transmitting analog signals. They were basically used for cable television and early versions of video recording.

Analog signals transmit data through continuous waves, while digital signals transmit data by encoding the information into bits, resulting in better fidelity and clarity. That’s why coaxial cables have a limited bandwidth which is significantly lower compared to newer digital cables such as HDMI or DisplayPort.

Is It Possible to Get 1080p Resolution Through Coaxial Cables?

To transmit 1080p resolution, a digital signal needs to have a minimum bandwidth of 4.95 Gbps (gigabits per second). Unfortunately, coaxial cables use analog signals and they do not have the required bandwidth to transmit a 1080p signal over long distances.

Coaxial cables can carry a limited amount of data which is suitable for standard definition (SD) or 720p high-definition (HD) resolution. Thus, coaxial cable can transmit 1080i, not 1080p.

To transmit 1080p video signals, it is generally recommended to use cables specifically designed for high-definition videos. HDMI (High-Definition Multimedia Interface) cables or DisplayPort cables can transmit 10080p efficiently as they have the higher bandwidth required for transmitting 1080p. 

Why Can’t You Get 1080p Through Coaxial?

The coaxial connection can offer 720p or 1080i instead of 1080p. Here the “i” in 1080i stands for interlaced, while the “p” in 1080p stands for progressive scan. For a progressive scan, it needs to show all lines at the same time while an interlaced scan required half lines. This means it requires twice the bandwidth of an interlaced scan.

In 1080i, each frame is transmitted as two fields, with half the resolution of the full frame. This means that the bandwidth requirements for 1080i are lower compared to transmitting the entire frame in progressive scan (1080p). Coaxial cables have sufficient bandwidth to carry the 1080i signal but it isn’t enough to carry 1080p.

Bonus Tip: Special Coaxial Cable That Can Transmit 1080p

There are some special types of coaxial cables like RG6 (Radio Guide 6), RG11, and RG59 that can transmit 1080p high-definition (HD) video signals. These coaxial cables have sufficient bandwidth and shielding to handle the higher frequencies required for transmitting 1080p video signals without significant loss or interference.

• RG6 is mainly used for Internet, Cable TV, and Satellite TV signals.
• RG59 is basically used in analog CCTV applications and other audio-video applications.
• RG11 can transmit HD signal on long-distance and they are mainly used in television connections, CCTV connections, and HTDV.

FAQs (Frequently Asked Questions and Answers)

Can You Get 4K Through Coaxial Cable?

No, coaxial cable can transmit analog signals which require lower bandwidth. Transmitting 4K requires a higher bandwidth which lacks coaxial cables. You can go for an HDMI cable to get 4K through it.

What Resolution Can Coaxial Cable Handle?

Coaxial cable can handle up to 1080i resolution. You can get HD signals like 720p through a coaxial cable. However, some coaxial cables can transmit up to 1080p but it depends on the length and connectors of the coaxial cable.

Do You Need Special Coaxial Cable For HD?

Coaxial cables can transmit Standard Definition (SD) and High Definition (HD) signals. You can get 720p or 1080i from a normal coaxial cable. To get 1080p, you’ll need special coaxial cables like RG-6, or RG-11.

Can You Get Gigabit Over Coax?

Yes! You can get Gigabit over coax. You can achieve a download speed of 50 Mbps to 1 Gbps with coax. 

Conclusion

It is true that coaxial cables were popular for audio and video transmission in the past, but they are not the ideal choice for transmitting high-definition signals like 1080p due to their limited bandwidth. If you want to get the full benefits of 1080p resolution, you are advised to use digital transmission technologies such as HDMI or DisplayPort cables.
