Coaxial cable LMR 400-75 is frequently used for commercial and industrial applications. Most commonly, in the transmission of video, audio, network or other communication signals. These cables are actually known as coaxial however, many people refer to them by their shorthand "coax". So, what does coax, or coaxial mean?

Simply put, coaxial means that the cable has two concentric conductors. These conductors are separated by an insulating material. Basically, an insulating material creates a space between the conductors. This serves to reduce signal leakage. Occasionally, there is another insulating layer outside the shield. In most cases, the inner conductor is designed to carry the signal carrying voltage while the shield stays at ground potential. The outer conductor operates as a conducting shield. Why create a cable like this? The design of this cable is beneficial for a multitude of reasons. The most important reason is that this type of cable restricts magnetic and electric fields. The fields are basically bound in the internal insulating material. This is how it reduces leakage outside the shield as I mentioned above.

What does LMR stand for? Originally, it stood for Land Mobile Radio and was used by the military. Since then it has become multipurpose and is used in a variety of industries. LMR is associated with "Low Loss" coaxial cable. What distinguishes this
from other coaxial cable is its conductor size and signal carrying capability. Additionally, LMR 400-75 has a thicker, more durable exterior jacket making it perfect for outdoor conditions. Up to 20 years outdoors to be exact. Selecting the correct coaxial cable is not an easy task. Contact a Pacer Group expert today with any questions you may have.
