Belling-Lee connectors are one of the oldest types of coaxial connectors and are still widely used in many countries across the world. Commonly known as PAL connectors or TV aerial plugs, these connectors have been named after the company which designed them Belling and Lee Ltd. Apart from television, these RF connectors are used in radio sets too: why? Easy wiring and installation. This 2 wired coaxial cable connector is available in various modifications- different casings, plating over the connecting nib etc. Even in terms of sizes there are two types: standard and miniature. The structure of these connectors is quite similar to the conventional RF connectors but they have an extra insulation over the tip where the connectors interface with the device. Let’s learn more about the Belling-Lee connector and their internal structure in this Insight.
