There are over 17 types of coax cable today, used in a variety of applications such as TV, radio, older computer networks, medical and electrical test equipment. It is used in both short and long distances where high bandwidth applications at high frequencies require protection from electromagnetic interference. From corporate television networks to high-end medical equipment, Trident has a solution that will fit your needs.

What is "Impedence"?

Impedence is a means by which the electrical output matches the electrical input across the line. For most coax cables, the standard impedence is either 52 Ohms (commonly referred to as 50 Ohms) and 75 Ohms. By matching the impedence of the line, reflections can be reduced in high-frequency applications, making the cable more efficient.

What does "RG" stand for?

Coax cables use a "RG" designator to describe them (i.e. RG-6). The term RG is an archaic military term standing for Radio Guide. This military standard dates all the way back to World War II, and though obsolete today, it is typically used to describe the connector that is now used at each end of the cable.
Coaxial cable consists of inner conductive cable, an insulating spacer, a conducting shield and an outer insulating layer.The inner conductor is shielded from outside electromagnetic interference.

FUN FACT: The first coax cable was patented in England by Oliver Heaviside in 1880 (patent no. 1,407), an engineer and mathematician. Oliver is created with coining many electrical terms, including impedence, inductance and conductance.
