How Do Standing Waves Arise In Transmission Lines?

Standing waves are unpleasant effects that happen when two or more waves of the same frequency are present at the same time, travelling along the same medium. This often happens when the transmission line, antenna or the transmitter are not matching with each other correctly. Standing waves can minimize the quality of the transmitted signal and can even cause the transmitter to malfunction.

A good quality coaxial cable can broadcast the transmitter's radio signal to the antenna with a minimum loss of signal strength. Coaxial cables are normally made of two concentric conductors divided by an insulating material and covered by a jacket which is weather-resistant. Pre-made cables are advisable for General Radio Services (GRS) use. These cables come with connectors pre-installed and are known to reduce problems from standing waves. To avoid problems from standing waves, make sure that you do not bend, flatten or handle the cable too harshly during the installation.
