What is 1 2 Feeder Cable (1/2'')?


To start with, let's be clear about what is a feeder cable. 


Specifically, a feeder cable is a type of RF coaxial cable that is used to transfer radio frequency energy from one point to another.



In the field of RF transmission, a feeder cable is used as a transmission feed line for radio frequency signals that connect radio transmitters and receivers with their antennas. A feeder cable also provides protection for the signal.


And the 1/2 super flexible coaxial cable, which is named half inch coaxial cable, refers to a specific size of coaxial cable that is made of the following parts:


  • 16mm PE Shield (or PE jacket)
  • Corrugated copper tube
  • 12mm foam dielectric
  • Copper conductor (hollow or solid)

Inside the 1 2 Feeder Cable (1/2'')


Inside the cable coaxial 1 2 Superflex feeder cable, there is an inner copper-made conductor which is surrounded by a tubular insulating layer (mostly called a foam-made dielectric), which is then surrounded by a tubular conducting shield with an insulating outer sheath or jacket.



Coaxial cable 1 2 is closely related to some keywords such as low loss, foamed insulated, 50ohm, corrugated, copper, etc, and its main task is to efficiently transmit signal energy.


The connectors and attachment are as followed:


N Машки Тип на стегач Crimp Type
4.3-10 Male Тип на стегач Crimp Type
TNC Машко Тип на стегач Crimp Type
DIN Male Тип на стегач Crimp Type




As for the specifications, because of various applications, thus there are different specifications of coax feeder cable, for feeder cables, diameters are used as the unit, for example, the most-heard ones are 1 2 coax, 7/8'' feeder cable, 1-5/8'' coax cable, 8D feeders, and 10D feeders. etc. 




Generally, the larger the diameter of the feeder the smaller the signal attenuation, and 1 2 feeder cable is probably the smallest size above all the others in terms of feeder cable.

What is the Packaging of a 1 2 Feeder Cable?


First of all, a feeder cable never comes out of thin air. It must go through the following production processes, including production, testing, packaging, and delivery. Details are as followed:






  • Тестирање на материјал
  • Insulation extrusion
  • Braid wire sort
  • Braiding extrusion
  • PE jacket




Then, our R & D team will carefully test each feeder cable to make sure that they can remain high quality.





These feeder cables will be tied to the requirements of different customers, for example:


  • Се тркалаат
  • Wooden Drum
