Wirewin Low Loss HF Coax Cable H-155, 48 dB/100m at 2.4 GHz, 50 Ohm, No Connectors

At 2.4 GHz, this coaxial cable attenuates only 48 dB per 100 meters, making it a strong candidate for WLAN, GSM, and GPS installations where signal integrity over distance matters. The H-155 design combines a solid copper inner conductor with dual shielding—copper foil plus a 90% coverage tinned copper braid—to keep interference low and performance consistent.

Overview

The Wirewin H-155 is a low-loss 50 Ohm coaxial cable built for RF communication up to 3 GHz. Its foamed polyethylene dielectric and 79% velocity of propagation contribute to efficient signal transfer, while the PVC jacket protects the cable in indoor and light outdoor environments. With an outer diameter of 4.95 mm, it balances flexibility and durability for routing through equipment racks or conduits.

What stands out

• Low attenuation: 48 dB/100m at 2.4 GHz, 26.5 dB/100m at 1 GHz, 16.5 dB/100m at 400 MHz
• Dual shielding: copper foil plus tinned copper braid with 90% coverage
• Solid copper inner conductor (0.81 mm) for reliable signal transmission
• Wide frequency range: DC to 3 GHz, suitable for WLAN, GSM, GPS
• Compact 4.95 mm outer diameter with a minimum bending radius of 25 mm (single bend)
