How to buy the best coaxial cable for the modem?

You may know that the coaxial cables are better than the other types of shielded cables. They provide uninterrupted signal transfer from the source to the destination device. But, as not all the coax cables are same and durable, you need to pick the best from the lot to have a real value for your hard earned money.

Check the below factors before buying a coaxial cable.

Cable type

Though most of the cable types work efficiently, for particular kind of needs (like here for a modem), there is a specific cable category you need to choose. For getting a high-speed Internet on the modem, you should opt for the RG6 type of coaxial cable as it works ideally on the Internet devices.

Build

A good-quality coax comes with a thin plastic layer on a central conducting wire. Then, it has the insulating surroundings of mesh and an enclosure of the rubber material. Also, it should have multiple layers of aluminum foil or braided wire for further insulation. The PVC outer layer of the cable provides it strength against the unusual weather conditions and make it ideal for use in both the indoor and outdoor installations.

Connector type

Three types of connectors are most common; RCA, BNC, and F-type. While RCA and BNC connectors are ideal for special purposes, when you are looking for the best coaxial cable for the Internet modem, TVs, DVDs, etc. then you should select the wire with an F-type connector.

Length

This factor is also considered when you are making a hassle-free, affordable, and perfect cable management. Choose the right length of the coaxial cable according to the approx distance between your modem and other connecting devices. Yes, it is perfectly fine to get a couple of feet longer cable, but it is entirely worthless to get a wire with almost double length than you need and never to extend it. Also, a too lengthy cable creates a mess of wiring and can make the signal a little bit slow.

Price & warranty

Both these factors are if not necessary, then recommended. Always check the price and warranty of the product before you buy. A branded coax always come with the company’s support. Also, you should spend your hard earned money on the product only that you find perfect for your needs.

So, all in all, an excellent coaxial cable for modem comes with a robust design with proper insulation, the right type of connectors, standard ratings for indoor and outdoor uses, the desired length according to the setup, budget-friendly price, and a worry-free warranty from the company.

Conclusion

For millions of people in the world, the TV or a computer system brings entertainment, news, and educational programs into their homes and offices. For that, many of them use the Internet services of the cable operators and desire for a high-speed Internet connection. With all the recommended network setup devices for getting what you need, a compatible coaxial cable for your router is also an important thing.

All the coax wires listed in this article are tested and reviewed by the experts to work correctly with the Internet modems. So, you can choose the most suitable for them according to your requirements and budget.

Don’t forget to mention your favorite choice in the comment section below.

Thank you & enjoy the high-speed Internet.
