Coaxial cables have been largely utilized for many years; they provide high-frequency signal transmission, which makes them ideal for different purposes that include commercial radio and cable television.
Created over 100 years ago by Oliver Heaviside, coaxial cables are electrical copper-based wire cables that have internal conductors enclosed by a tubular protective layer and covered by a metallic shield and a synthetic outer jacket.
The name coaxial has its origin from the internal conductor and external shield sharing one geometric axis.
The main differentiation and what makes coaxial cables different from other shielded cables is the capacity to operate as transmission lines by controlled cable dimensions with continuous conductor spacing.
One of the advantages of Coax cables is that they are compatible with most daily use electronics. Even though there are a handful of coaxial cables, a commonly appearing cable type in-home, and residential settings is the RG-6 Cable.
The RG Cable has changed considerably and evolved in importance since its days of initial use. The RG term actually stands for “Radio Guide” and originates from World War II; The RG Cable was employed for U.S. military specifications as it was initially a unit indicator for bulk radiofrequency.
This is the reason why the cables are associated with numerical values, as each kind of coaxial Cable had a distinct RG rating with specific characteristics and specifications. If the RG cable was also designated with a “U,” it indicated “universal” or a general utility application.
The numbers associated with RG cables are somewhat irrelevant nowadays since they are only for specifications of the original Radio Guide, which is now obsolete. These industry-fundamental coax cables are still referenced by their original names, like the frequently used RG6. This RG option is utilized in an extensive range of consumer applications becoming an industry standard.
RG cables can reduce static and increase picture quality. Utilized for hi-def signals in the home and commercial entertainment systems, these cables are available in several variations for specifications that include underground or moisture-prone areas.
RG6 Coaxial Cable
The RG6 coaxial cable is typically employed for cable and satellite signal transmission for both residential and commercial installations. This coaxial cable is thin and easy to bend for wall or ceiling connections which makes it ideal for these applications; that is one of the reasons why it continues to be the most favored and recommended choice to relay cable television signals.
The cable has a large conductor and thicker dielectric insulation that offers more reliable signal quality and makes it less likely to carry damaging electric currents.
The RG6 coax cable utilizes better shielding that makes it compatible with GHz level signals and gives better protection from signal interference.
Other RG cables
Other RG cables are still applicable in today’s industry, like the RG11, designed mainly to run outdoors or underground, and the popular RG59, known to work for low-frequency transmissions. But, the RG6 has become the standard and displaced other coaxial cables in recent years.
These coaxial cables have become omnipresent in cable installations and can be utilized for multiple applications and with numerous electronic systems. The RG-6 cables are also affordable for their use and compatibility.
