Type

Coupling mode:1/2", 7/8", 7/8"Low loss,1-1/4"

Radiating mode:1/2", 7/8", 1-1/4", 1-5/8"

Structure

Inner conductor, Insulation, Outer conductor, Jacket.

Application

Leaky cable is mainly used in the long, narrow and enclosed areas that conventional antenna signals can not be effectively covered, for example: track traffic, tunnels, mines, buildings and large edifices, and so on.

Advantage

Its product has the advantages of high compatibility, low system loss, low field strength, uniform ration.

Standards

The company does design and production according to international standards of YD/T 2491,YD/T 1092,YD/T 1119,GB/T 17737.1,GB/T 15285,MIL-C 28830,IEC 61196-4,YD/T 1319.

Structure

Inner conductor (Copper wire, copper clad aluminum), Insulation (Foamed polyethylene), Outer conductor (Coupling leaky cable adopts structures like argon arc welding corrugated copper tube milling groove; Radiating leaky cable is longitudinally wrapped by  punched copper foil), Jacket (PE or LSZH)

Characteristics

a. Operation temperature:-30°C+80°C

b. Low attenuation,Low Voltage Standing Wave Ratio;Superior bending performance;Broader frequency band;well third-order intermodulation performance;Long service life

c. Our Radial leaky cable has a longer radial action distance and lower coupling loss;it has a certain frequency band range,and resonance frequency,but various performances have been optimized at a specific frequency. We shield the unused frequency band (similar to the filter The function), it can have a strong suppression ability to interference signals outside the working frequency, so the anti-interference ability of the network is improved.

d. Our coupled leaky cable has a short radial action distance and high coupling loss; it has a wide frequency band, no resonance frequency, and no anti-interference ability in the full frequency band.
