ASTEL 7/8 Inch Flexible RF Feeder Cable – Full Copper, 50 Ohms, Low PIM
ASTEL 7/8 Inch Flexible RF Feeder Cable is a full copper, 50 Ohm low PIM coaxial cable designed for VHF, UHF, GSM, 3G, 4G and 5G wireless communication systems. It provides low attenuation, low VSWR and high power handling for cellular base stations, antenna feeder networks and professional RF transmission applications.
Featuring a smooth copper tube inner conductor, three-layer foamed PE dielectric and corrugated copper tube outer conductor, the cable offers high shielding effectiveness of ≥120 dB and PIM3 performance of ≤-155 dBc. Available with PE and LSZH jacket options, it is designed for demanding RF installations requiring stable electrical and mechanical performance.
