HLCTYZ(R)-50-22H2 Indoor Leaky Coaxial Cable

The indoor leaky cable HLCTYZ(R)-50-22H2 consists of a low-loss smooth copper tube inner conductor, a low-loss physically foamed polyethylene insulation layer, a low-loss broadband wide-beam radiation copper foil outer conductor with “8”-shaped slots of small pitch, and an LSZH flame-retardant polyolefin outer jacket. This product is designed for indoor environments. Its 5 dB beamwidth in the main radiation direction is controlled at about 180°, and it is suitable for many systems such as civil 3G/4G/5G and WLAN 2.4G. It features low loss, broadband and wide beamwidth characteristics and excellent bending performance, and is suitable for use as main and secondary trunk routes in indoor coverage.
