Coaxial Surge Protector

Does coaxial cable need surge protection?

Yes, coaxial cable needs surge protection. If coaxial cable is connected to valuable equipment, reliable surge protection is necessary.

When a surge current is generated by a direct lightning strike or an operational overvoltage, the coaxial cable will become the conductor of the surge, which may damage connected equipment such as signal receivers or TVs.

As networks become more important and complex, sensitive network equipment needs to be protected from transient voltage spikes, and coaxial surge protectors play a vital role.

What is a coaxial surge protector?

Coaxial surge protectors can protect applications using coaxial cables from surge currents.

Coaxial surge protectors are used to connect between coaxial cables and other equipment to protect equipment from surge currents transmitted from the coaxial cable.

Coaxial surge protectors have a ground terminal that will guide surge currents that exceed the safe range to the ground.

Consider a high-quality coaxial surge protector to ensure a stable, reliable, and long-lasting connection.

Where should I put the coaxial surge protector?

People have been arguing about where the coaxial surge protector should be placed. Some people think that the coaxial surge protector should be placed on the antenna side, while others think that the coaxial surge protector should be placed on the device side.

The coaxial surge protector should be installed on the coaxial cable where the outdoor antenna enters the electrical distribution box or the building in series, and it also requires reliable and good grounding.

It should be clear that the installation location of the coaxial surge protector is affected by the equipment to be protected and the actual application requirements. The following three places are common installation locations for coaxial surge protectors, namely the antenna side, the equipment side, and the distribution box.

Install the coaxial surge protector close to the antenna side: This coaxial surge protector installation arrangement can intercept any surge current from the external antenna and is a common installation method. Protect the overall internal electrical system of the building and the equipment in the electrical system from the impact of surge current.

Install the coaxial surge protector close to the device side: This coaxial surge protector installation arrangement can be used to protect sensitive electronic equipment. Since each device has a different resistance to surge current, some sensitive electronic equipment will be damaged by slight voltage fluctuations.

Install the coaxial surge protector in the distribution box: This installation layout of the coaxial surge protector can protect multiple coaxial cables. In some electrical system layouts, there will be a distribution box to manage multiple coaxial cables. This installation method saves costs, simplifies later maintenance, and unifies the surge protection standards of multiple coaxial cables.
