30meter RG-178 RG178 B/U Coax Wire 50 ohm Teflon RF coaxial cable for radio broadcasting FM transmitter use
RG-178 RG178 B/U Coax Wire 50 ohm Teflon RF coaxial cable for radio broadcasting FM transmitter use Coaxial cable refers to two concentric conductors, and conductor and shield they share the same axis of the cable. The most common coaxial cable insulation material isolated from the copper conductor formed in the inner layer is a layer of insulating material of the external conductor and an insulator ring, then the cable is made from PVC or Teflon material of the sheath wrap. Currently, there are two types of commonly used coaxial: 50Ω and 75Ω coaxial cable. 75Ω coaxial cable used in CATV network, it is known

RG-178 RG178 B/U Coax Wire 50 ohm Teflon RF coaxial cable for radio broadcasting FM transmitter use
Coaxial cable refers to two concentric conductors, and conductor and shield they share the same axis of the cable. The most common coaxial cable insulation material isolated from the copper conductor formed in the inner layer is a layer of insulating material of the external conductor and an insulator ring, then the cable is made from PVC or Teflon material of the sheath wrap.
Currently, there are two types of commonly used coaxial: 50Ω and 75Ω coaxial cable. 75Ω coaxial cable used in CATV network, it is known as CATV cable, transmission bandwidth up to 1GHz, currently used as a CATV cable transmission bandwidth 750MHz. 50Ω coaxial cable is mainly used for baseband signal transmission, the transmission bandwidth of 1 ~ 2OMHz, bus, Ethernet is the use of 50Ω coaxial cable in the Ethernet, 50Ω thin coaxial cable with a maximum distance of 185 meters, thick coaxial cable up to 1000 meters.
If you use ordinary wire transmission of high frequency current, the wires will be transmitting the equivalent of a radio antenna outside, this effect is loss of signal power, making the received signal strength decreases.
Coaxial cable is designed precisely to solve this problem. Center wire mesh emitted radio was isolated conductive layer, conductive mesh layer can be ground to control the emitted radio.
Attention:
If you buy 100 meters, the price will be USD199 only with free shipping through DHL.
