The Ubiquitous RG-11 Coaxial Cable
The RG-11 coaxial cable has been around for many decades. The original purpose for the RG-11 cable was for radio transmission and sound control at theaters and concerts. With the advent of the Information Age, the RG11 cable has become a household staple and is available in varying styles on eBay.
What is the RG 11 cable used for?Some uses for RG11 cable may include:
- Community access television: Community access and high-definition television systems use this cable as the cables are capable of carrying a larger signal.
- Home television and amateur applications: Home televisions, amateur radio operation, and any other systems that use antenna linkages.
- Onstage performances: Connections for onstage performances between instruments and splitters/amplifiers.
- Computer trunk lines: Computer trunk lines at individual locations.
- Linkage between film cameras: Linkage between film cameras and video recording machinery at every film stage throughout the industry.
RG11 coaxial cable has a thicker copper wire with additional sheathing that extends the ability of the wire to carry information from one location to another. The principal advantage of the RG-11 cable is its lack of attenuation (signal loss) allowing the cable to be used as a long distance signal carrier. The RG-11 coaxial cable also has a lower impedance (signal barrier) factor. The cable is capable of carrying 3Ghz of information making it a useful tool when applied as a building trunk line.
Where can RG-11 coaxial cable be used?This cable can be used for most applications. The cable is sheathed against the elements as well as against signal loss. As a waterproofed cable, the RG-11 finds itself used to carry information along the outside of buildings, across streams, between poles when elevation is necessary and underground. Even the fastenings between cable lengths are proof against water invasion. These characteristics make the RG-11 the standard cable against which all other methods of information carriers are measured.
How is RG-11 coaxial cable produced?There are several companies that produce this cable. Some are superior to others mainly because of the sheathing material used to inhibit signal loss. Due to the nature of its use, RG-11 cable comes from the factory in measurements of up to 5,000 meters in length. From there, most installers use specialized tools to cut appropriate lengths and add fittings for the job at hand. Those lengths could be the complete 5,000 meters for business trunklines or as short as 10-15 meters for home theater units. You can order shorter lengths from various manufacturers or find them online at eBay.
