ASTEL 1-5/8 Inch Flexible RF Feeder Cable – 50 Ohms
ASTEL 1-5/8 Inch Flexible Series is a 50 Ohm RF coaxial feeder cable designed for professional antenna feeder and wireless communication infrastructure. Its construction features a helical copper tube inner conductor, foamed PE dielectric, longitudinally welded spiral copper tube outer conductor and durable PE jacket.
The cable provides 50 ± 2 Ohm impedance, return loss of ≥23 dB, VSWR of 1.15 and an 88% propagation velocity ratio. With a 49.50mm nominal jacket diameter and operating temperature range of -40°C to +70°C, it is suitable for large RF feeder installations requiring stable electrical performance and mechanical durability.
