SYKV-75
TYPE RADIO FREQUENCY COAXIAL CABLE
PRODUCT INTRODUCTION:
With semi-air as insulation,SYKV type polythene cotes root-shaped
medium
radio frequency coaxial cables have the following features,when applied to
telecommunication:
1.Low transmission loss wide working frequency band
2.Light weight,easy to install
3.Stable & reliable electric properties
SYKV type coaxial cables are suit for the transmission system of VHF &
UHF signals in CATV and closed circuit television ,as feed lines of trunk
lines,branch lines and other electronic equipment the system.
