N Male To Sma Male Rf Jumper Cable Rg142

These N Male to SMA Male RF Jumper Cable RG142 is a basic cable used primarily for carrying audio-visual signals. The name comes from an abbreviation of "radio frequencies." The RF cable is a type of coaxial cable, which involves a series of casings to protect the signal from interference.
The coaxial design used in an RF cable is designed to prevent the potential problem of the wire carrying the signal also acting as an amplifier. This could cause some of the signal to be lost in the form of radio waves. To counteract this, the coaxial cable uses four circular layers. From the inside to the outside they are: the wire carrying the signal; an insulating material which is usually solid plastic; a metal shield; and a plastic casing which protects the materials inside.
These N Male to SMA Male RF Jumper Cable RG142 has several important drawbacks. It can only carry sound between two devices in mono rather than stereo. As well as being unable to produce a stereo signal, this also means it can't carry surround sound information broadcast in Dolby Pro Logic. This means that if RF cable is used, it is impossible to get true surround sound audio even when using a decoding receiver.Another drawback is that while the design of the cable does block interference in theory, in practice this is often not achieved. Cables, particularly cheaply made ones, can be subject to interference from magnetic sources or power cables. This can lead to visible picture interference such as ghosting.
