Product Description
|
|
KAI® 50 ohms radiating coaxial cable is mainly
used in tunnel, mine, subway, high building and
high way where there is no direct or good radio
wave as signal transmission and transmitting and
receiving antennas duplex functions. The cables is
characterized with low attenuation, low VSWR, high
power capacity, good signal coupling and corrosion
resistance.
The cable is manufactured on argon arc welding,
corrugating and slotting production line with the
most advanced technology by slotting the holes
along outer conductor axis. So the
evenly-distributed relatively strong radiating
signal in the close vicinity of the cable along ts
axis make it possible signal transmission, across
long distance in uncovered area.
