Difference Between RG-6 and RG-59 Coaxial Cables

All coaxial cables are constructed with a steel, copper, or aluminum conductor core, which is surrounded by a layer of white/black dielectric insulation. This is further covered with a tube-like braid of copper wires, which is wrapped around by a solid polyvinyl chloride insulating cover called a jacket. Some coaxial cables may have a layer of foil between the dielectric and the conducting core. Coaxial cables use the RG system to differentiate between the various kinds of cables. RG stands for an obsolete military term ‘Radio Guide’. The numbers are used to distinguish one cable from the other, but they are assigned randomly and carry no specific meaning.

RG-6 and RG-59 are two of the most common varieties of coaxial cables, i.e., cables that conduct electricity to transmit signals of radio frequencies, computer networks, and cable televisions. You may also find these cables designated as RG-6/U or RG-59/U, but there is no difference. Both types differ in their construction, uses, and range of capabilities. We shall now look at how one can tell the difference between RG-6 and RG-59 coax cables, and identify one from the other.

How to Identify RG-6 and RG-59 Cables

Construction: Ideally, to identify if the cable is RG-59 or RG-6, one only has to look at the jacket/outer covering, where the details of the cable are printed. However, if this printing is not visible, look for the thickness and the flexibility of the cable. Both cables have 75 Ohm resistance. However, the RG-59 cable has a 22 American wire gauge center of multiple strands of wire, while the RG-6 cable has 18 American wire gauge center with a solid copper core. This means that the RG-59 cable is smaller in diameter than the RG-6. Further, RG-6 cables can have additional foil and wire braid shields along with thicker dielectrics, which reduce the flexibility, lessen the degradation of signals, and are able to carry such signals for longer distances.

Selection of Coaxial Cables: RG-59 cables are best used where transmission distances are short, and the frequencies used are lesser than 50 MHz. Therefore, they are ideal for CCTV security camera networks. Using frequencies larger than 50 MHz will cause electromagnetic interference and degradation of the signal. In cases where transmissions are needed for long distances or signal frequencies of up to 1.5GHz, RG-6 cables are the best. Thus, they are ideal for TV antennas, satellite transmissions, and high-speed Internet broadband. Also, RG-6 cables have thicker and more durable jackets, which make them more suitable as compared to RG-59 cables for outdoor use.

RG-6 vs. RG-59 Coaxial Cable Performance

Operating Frequencies: RG-59 is made for appliances that require signals of frequencies lower than 50 MHz, such as high-definition plasma televisions or video projectors. However, this cable is unable cope with signal frequencies which run in GHz, because the wiring and shielding is too thin. Therefore, the quality of the signal is lowered, and it cannot be used for satellite and cable transmissions.

RG-6 is a thicker cable with a large conductor, which allows it to process better signal quality through higher frequencies than RG-59 with reduced signal degradation. This also makes it good for satellite, cable, and high-voltage transmissions for TV antennas. On the other hand, RG-6 cannot handle low frequencies below 50 MHZ.

Signal Loss: RG-6 cables generally have better shielding than RG-59. This means that signal loss is lesser. Signal loss for RG-59 cables at 50, 400, and 1,000 MHz per 100 feet is 2.4, 7.0, and 12.0 decibels, respectively. The same for RG-6 cables is 1.5, 4.3, and 7.0 decibels. Higher quality of signals and additional materials make RG-6 slightly more expensive than the RG-59.

As you can see, the RG-6 cable has the edge over the RG-59 cable. With the continuous, rapid advances of communication systems around the world, the use of RG-6 cables will increase significantly over that of RG-59 type.

Different Types of Servers

A server is a device with a particular set of programs or protocols that provide various services. Together, a server and its clients form a client/server network, which provides routing systems and centralized access to information, resources, stored data, etc.
At the most ground level, one can consider it as a technology solution that serves files, data, print, fax resources and multiple computers. The advanced server versions, like Windows Small Business Server 2003 R2 enable the user to handle the accounts and passwords, allow or limit the access to shared resources, automatically support the data and access the business information remotely. For example, a file server is a machine that maintains files and allows clients or users to upload and download files from it. Similarly, a web server hosts websites and allows users to access these websites. Clients mainly include computers, printers, faxes or other devices that can be connected to the server. By using a server, one can securely share files and resources like fax machines and printers. Hence, with a server network, employees can access the Internet or company e-mail simultaneously.
Types of Servers
Server Platform
Server platform is the fundamental hardware or software for a system which acts as an engine that drives the server. It is often used synonymously with an operating system.
Application Server
Also known as a type of middleware, it occupies a substantial amount of computing region between database servers and the end user, and is commonly used to connect the two.
Audio/Video Server
It provides multimedia capabilities to websites by helping the user to broadcast streaming multimedia content.
Chat Server
It serves the users to exchange data in an environment similar to Internet newsgroup which provides real-time discussion capabilities.
Fax Server
It is one of the best options for organizations that seek minimum incoming and outgoing telephone resources, but require to fax actual documents.
FTP Server
It works on one of the oldest of the Internet services, the file transfer protocol. It provides a secure file transfer between computers while ensuring file security and transfer control.
Groupware Server
It is a software designed that enables the users to work together, irrespective of the location, through the Internet or a corporate intranet and to function together in a virtual atmosphere.
IRC Server
It is an ideal option for those looking for real-time discussion capabilities. Internet Relay Chat comprises different network servers that enable the users to connect to each other through an IRC network.
List Server
It provides a better way of managing mailing lists. The server can be either open interactive discussion for the people or a one-way list that provides announcements, newsletters or advertising.
Mail Server
It transfers and stores mails over corporate networks through LANs, WANs and across the Internet.
News Server
It serves as a distribution and delivery source for many public news groups, approachable over the USENET news network.
Proxy Server
It acts as a mediator between a client program and an external server to filter requests, improve performance and share connections.
Telnet Server
It enables the users to log on to a host computer and execute tasks as if they are working on a remote computer.
Virtual Servers
A virtual server is just like a physical computer because it is committed to an individual customer’s demands, can be individually booted and maintains privacy of a separate computer. Basically, the distance among shared and dedicated (hosting) servers is reduced providing freedom to other customers, at a less cost. Now, it has become omnipresent in the data center.
Web Server
It provides static content to a web browser by loading a file from a disk and transferring it across the network to the user’s web browser. This exchange is intermediated by the browser and the server, communicating using HTTP.
Other types of servers include Open source servers, Gopher server (like a plain document, similar to WWW and the hypertext being absent), and Name server (applies name-service protocol).

The various servers can be categorized according to their applications. Servers along with managing network resources are also dedicated, i.e., they perform no other task other than their server tasks.
