50Ω Radiating Coaxial Cable Antenna Factory 50 ohms radiating coaxial cable is mainly used
in tunnels, mines, subways, high buildings and highways where
there is no direct or good radio wave as signal transmission and
transmitting and receiving antennas duplex functions. The cable
is characterized with low attenuation, low VSWR, high power
capacity, good signal coupling and corrosion resistance. |
