History

Coaxial Cable, patented in 1880 by Oliver Heaviside, was one of the first shielded cable designs in history. Originally intended to battle radio interference (RMI), this cable has proven its usefulness by remaining a mainstay in the telecommunications world for over 100 years. 

RG Coaxial Cable proved very useful in combatting the radio interference, but as technology progressed and more radio interference and even electromagnetic interference (EMI) began to overcome the older designs of cable. 

Of course, since its creation, many revisions have been made to Heaviside’s design of coaxial cable, with one of the most valuable versions of the wire being Low Loss Coaxial Cable. But what differentiates this cable from standard RG Coaxial Cable?

Low Loss Coaxial Cable

The primary utility of Low Loss cable is the lower rate of attenuation, or degradation of signal strength through the cable. This is achieved by increasing the amount of shielding on the cable throughout the length of the cable. While all Low Loss cables have lower attenuation than standard coaxial cable, there are many different sizes of the cable, each with differing degrees of shielding and signal strength. 

The number in the designation of many brands of low loss coaxial cable is roughly equivalent to the diameter of the cable, and is a good indicator of the level of shielding and attenuation. The TXM brand LOW600, for example, has a diameter of .59 inches, with a typical attenuation of 7.45dB/100ft, at a frequency of 6000MHz. However, larger cable is not without trade-offs. The increased shielding and diameter of the cable greatly increases the weight of the cable. Fortunately, Low Loss Cable comes in smaller variants that still manage to have a very low rate of attenuation. The TMX LOW195 is less than a fifth of the weight of the .600in diameter cable, while still maintaining a typical attenuation rate of only 28.2dB/100ft at 5800MHz. 

Of course, there are options between these two extremes such as the TXM LOW240 and TXM LOW 400 size Low Loss cables. If you require coaxial cables that are dependable, even in interference-heavy environments, Low Loss Coaxial Cable is perfect for you.
