Quad Shield Coaxial Cables: What Are They and Why You Need Them?


Are you an engineer or retailer that’s into HDTV network, digital satellite wiring, or digital CATV? And you love to get the most suitable wiring? Or are you looking for authentic cables that can run for a long distance without having signal breaks? Then, it would help if you considered the quad shield coaxial cables.

These cables don’t just have excellent data retention. They also help to transmit data at a SUPERSONIC speed.

So, they are most definitely an excellent wiring choice for enterprise-based projects.

However, you need to understand how these coax cables work and know if they are necessary for your project.

That’s why we have created this post as a guide to help your buying decision.

So, if you want to find out more about these cables, continue reading.

1. Understanding Quad Shield Coaxial Cables

Quad Shield Coaxial Cables

A lot of people often confuse the word “shielding” with “insulation.” No doubt, it’s tricky, but we’ll explain each term.

Insulation covers the protection of conductors. In other words, it stops cables from having direct and electrical contact with each other. Plus, it has insulation materials passing through each conductor.

In contrast, shielding provides adequate protection for the conductors against magnetic and electric fields.

Thus, a quad shielding of a coaxial cable helps to intercept electromagnetic fields. And that’s a feature that basic insulation can’t offer.

But that’s not all.

The quad shield coaxial cables stop the energy fields from arriving at the center conductor. And this peripheral is the coax where the signal transmits. Also, the shielding of the coax is a fantastic feature of the cable.  


It’s detrimental for the electromagnetic fields to hit the coax.

Types of Shield Coaxial Cables

They are two major types of shields—which are braid and foil.

One of the quad shield coaxial cables has braids. That is, it consists of a mesh with tiny wires. The second type has a foil protection.

Both shield types have various characteristics, which we’ll be talking about here.

1. The Foil Shield

The Foil Shield

This shield has the advantage of giving full protection. The foil shield does a great job in covering every piece of the dielectric cable.

Also, the foil bonds to the cables with the aid of a tape—known as mylar. Plus, it can endure significant flexing without sustaining any damage.

However, it has a few snags. The foil shield cables produce high resistance, making it difficult to have a perfect path to the ground.

Also, attaching connectors to the shield is quite tricky. And the ground connection at all sides of the cable may become compromised.

2. The Braid Shield

Braid Shield

This shield type doesn’t provide 100 percent protection like the foil shield. In short, this shield may have holes in the process of weaving. And the holes get bigger when you flex the cable, which reduces the shield’s effectiveness.

However, the braid shield has a few merits that make it stand out. It has an impressive connector and conductivity features.

Also, the shield has a higher mass than the foil shield cable. And this feature improves its conductivity level. Plus, its sheathes are perfect for attaching connectors—by crimping or soldering. Furthermore, this shield has a higher flexing capability than the foil shield.

2. The Advantages of Quad Shield Cables

The benefits of quad shield cables include:

1. It produces a top-notch connection—which grounds appropriately at each end of a cable.

2. The quad shield cables come with high coverage. Consequently, it’s difficult for energy to go through holes in the shield.

3. It has good conductivity—making energy that enters the shield to find the most straightforward path to the ground.

4. The shields also help to stop noise at various frequency levels.

3. Can a Quad Shield Rg 6 Support a Longer Distance

Yes, the quad shield Rg 6 cable supports a longer-distance coverage. In short, it can cover up to 1000 feet—which is different from the standard and dual-sided cables.

Typically, you can measure loss in a cable by checking the dielectric and center conductor’s size. So, the external shielding doesn’t play a significant role as such. But with the quad shield Rg 6 cable—foil or braid shield coaxial cables; you’ll get better performance.

4. How to Prepare a Quad Shield Rg 6

Quad Shield Rg 6

Preparing a quad shield Rg 6 coaxial cable is quite tricky because of its construction.

We’re going to list the tools and step-by-step guide you need to prepare the cables.

So, here are the tools you need to make the quad shield Rg 6 cable:

1. Cable cutter

2. Rg 6 quad compression connectors

3. Cable jacket stripper

4. Compression tool

The Steps required to Prepare a Quad Shield Rg 6

1. Trim the coax cable tip and press it back to form an oval shape.

2. Place the cable into the jacket stripper until it’s opposite the far sidewall.

3. Then, roll the stripper 2 – 4 times counterclockwise and clockwise.

4. Next, remove the stripped section of the cable from the stripper—giving the cable a “¼ x ¼” strip form.

5. Fold the outer braid layer.

6. Tear off the outer foil layer

7. Fold the inner braid layer inside.

8. Place the cable inside the compression connector until the dielectric and the connecter’s underside flushes in together.

9. Next, add the cable to the compression tool. Then, press the compression tool down to clip the connector to the cable.

10. Take out the cable from the compression tool. Afterward, your connector will tightly fasten to the cable.

Closing Words

No doubt, you have a clearer picture of the quad shield coaxial cables.

So, you now know the different types, advantages, and how to prepare a coaxial cable. The next thing to do is to take the right action by purchasing the cables that best suit your needs.

But if you’re still finding it hard to make a buying decision, it’s okay!
