SYKV type polythene cotes
root-shaped medium radio frequency coaxial cable
| PRODUCT
INTRODUCTION |
With semi-air as insulation, SYKV type polythene cotus
root-shaped medium radio frequency coaxial cable has 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 cable 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. The structure and electric properties are listed in table 3 and table 4. |
