7/8" Radiating cable HLRCTCYZ-50-22M( 7/8"）Leaky cable

7/8" Radiating cable HLRCTCYZ-50-22M(7/8")Leaky cable

• 1、Leaky cable functions as a distributed antenna to provide communications in tunnels, mines

and large building complexes and is the solution for any application in confined areas.

2、Slots in the copper outer conductor allow a controlled portion of the internal RF energy to be

radiated into the surrounding environment. Conversely, a signal transmitted near the cable will        couple into the slots and be carried along the cable length.

3、This leaky cable utilize a low-loss cellular polyethylene foam dielectric and a Corrugated copper foil outer conductor which offers a superior electrical performance together with good bending properties.

4、This product is suitable for FM, TETRA350, TETRA800, GSM900,GSM-R and other wireless communication systems, with low loss and wideband characteristics.
