Feeder and Coaxial Cable

Feeder by material can mainly be divided into flat cable, coaxial cable, and optical cable. The most widely used kind of feeder is coaxial cable.

Coaxial cable refers to two concentric conductors, and the conductor and the shield that shares the same axis of the cable. The most common coaxial cable consists of a copper conductor insulated from the insulating material, and on the outside of the inner layer is another layer of ring conductor and its insulator, and the entire cable is covered by a jacket of PVC or Teflon material.

The Structure of Coaxial Cable

The Coaxial cable from the inside out is divided into four layers: the central copper (single strand of solid or stranded strand), plastic insulator, mesh conductive layer, and wire sheath. The central copper wire and the mesh conductive layer form a current loop. Because the central copper wire and mesh conductive layer for the coaxial relationship named.

Why Do We Need Coaxial Cable to Transmit Signal

Coaxial cable conduction AC rather than direct current, that is, every second there will be several times of the direction of the current reversal. If a high-frequency current is transmitted using an ordinary wire, the wire will correspond to an antenna that emits radio outwards, which forces the power of the signal so that the received signal strength decreases. Coaxial cable is designed to solve this problem. The radio emitted from the center wire is isolated by the mesh-like conductive layer, and the mesh-like conductive layer can control the emitted radio by grounding.

What Attention Do We Need Pay to Coaxial Cable

Coaxial cable has a problem, that is, if a cable is bend, twisted, or deformed, then the central wire and the conductive layer between the distance is not always consistent, which will cause the internal radio waves will be Reflected signal source. This effect reduces the available signal power. In order to overcome this problem, the center wire, and mesh conductive layer is added between layers of plastic insulators to ensure that the distance between them is always the same. This also causes the cable to be stiff and not easy to bend. (Note that not all cable are unyielding, Sanyuan have small flexible jumper cable (1/2''S) if you need)

Why Do We Need To Apply Feeder Clamp to Coaxial Feeder

The feeder cable is stiff and fragile, thus we must use special parts to fix feeder cable when laying. Feeder clamp is one of the essential fixing accessory. It can fix the cable firmly.
