Thus, 50 Ohm Coaxial Cable was selected as the ideal compromise offering high power handling AND low attenuation characteristics. However, there are few dielectric materials suitable for use in a coaxial cable to support 30 Ohm impedance. Most importantly, every end-user of FMUSER 7 8 coax will be promised with:įMUSER 7-8 feeder cable has reliable thermal conductivity, which is due to its excellent low attenuation characteristics, which provides a considerable product life, this will reduce the long-term operating costs of the radio stations.Survivalism & Self Sufficiency Topics > The HAM Radio BoardĮxperimentation in the early 20th century determined that the best POWER HANDLING capability could be achieved by using 30 Ohm Coaxial Cable, whereas the lowest signal ATTENUATION (LOSS) could be achieved by using 77 Ohm Coaxial Cable. In most FM/AM/TV broadcasting stations, our 7 8 coaxial cable can be easily deployed in the connection of the transmitter antenna systems More>įMUSER is the premium manufacturer of 7 8 feeder cable.

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

The shielding layer is composed of a copper tube. The shielding line is a transmission line wrapped in the signal line using a metal mesh woven layer. The shielding layer of the feeder consists of the shielding line. In the broadcasting equipment industry, 7 8 Feeder Cable has many aliases, such as:īecause 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:
