Coaxial Cable

What is Coaxial Cabling?

According to, Coaxial Cable is the primary type of cabling used by the cable television industry and is also widely used for computer networks such as Ethernet. Although more expensive than standard telephone wire, coaxial cable is much less susceptible to interference and can carry much more data.

What is the most common type of coaxial wire and cable used to carry video signals?

The most common coaxial type to carry video signals is RG-59 B/U type 75 ohm coaxial cable.

Do coaxial cables degrade over time?

Yes. Over time, a coaxial cable will degrade and need to be replaced in order to maintain the integrity of the signal.

Which types of coaxial cable does Allied carry?

We carry a large selection of coaxial cable products including triaxial, twinaxial, low loss coax cable, low noise, high power, and high temperature options. We also distribute RG coax cable products manufactured by Belden Cable and Alpha Wire Company.

What is the difference between coaxial, triaxial, and twinaxial cable?

Coaxial cable uses two conductors that share a common axis. In triaxial cable, there are three conductors that share an axis. Twinaxial is different because it uses two twisted conductors surrounded by a common shield. The conductors in twinaxial cable don’t technically share an axis but are twisted together, giving the cable the “feel” of a shared axis.

In what kinds of applications is coaxial cable used?

The coaxial cable family is commonly used in data processing equipment and information systems.

What does the “RG” stand for in the term “RG coax cable?”

“RG” is short for “radio grade.”

What should I consider when deciding which Coaxial Cable to buy?

Coaxial Cabling is designed for the transmission of high frequency signals with a minimum of loss. Coaxial wire and cable is offered with various configurations, and the most common ones are listed on the previous page. When purchasing coaxial cable, you should consider impendence, environmental temperature, working voltage, signal loss at specific frequencies, power rating and cost. If a type of coax cabling is not listed please contact our sales department.
