What is FMUSER 7 8 Feeder Cable?

 

In the broadcasting equipment industry, 7 8 Feeder Cable has many aliases, such as:

 

  • 7 ខ្សែ coaxial
  • 7 8 coax
  • 7/8'' feeder pipe
  • 7 8 feeder
  • 7/8 feed tube
  • 7 8 coax feeder

 

Because the appearance of the coaxial feedback tube is similar to that of the coaxial feed line and even the cable, there are often two methods that can be distinguished from each other:

The shielding layer

The shielding layer of the feeder consists of the shielding line. The shielding line is a transmission line wrapped in the signal line using a metal mesh woven layer. The shielding layer is composed of a copper tube.

 

ទំហំ

The feeder and the feeder are also very different in size. For the feed line, they are often very fine, and the common feeding line size is:

 

  • RG-6 (6.15mm)
  • RG-11 (10.30mm)
  • RG-58 (4.95mm)
  • RG-59 (6.15mm)
  • RG-62 (6.15mm)
  • RG-12 (14.10mm)
  • RG-213 (10.33)

 

The feedback tube is thicker, and the common feedback tube size is:

 

  • 1 / 2 ''
  • 7 / 8 ''
  • 1-5 / 8 ''
  • 3-7 / 8 ''

 

ការរចនាម៉ូដ

It is worth mentioning that for the first two types of sizes (1/2 and 7/8), there are two designs: hollow and solid conductor, and the latter two feeders are often empty designs, although hollow The cost of coaxial feedback tube is more expensive, its performance will be stronger than the solid feedback management, and it is more difficult to overhaul.

In addition to the difference in size, the performance is better than ordinary feeders, which is due to the unique design of the feeder, including Solid Shields, a foam dielectric, and a copper conductor.

 

To meet the needs of different customers, we also provide the hollow 7 8 feeder cables, which are more flexible and bendable than the solid feeder cables. Please contact our sales team if you need more details!
