TestPro 4.2 Cable Assemblies Radiall TestPro 4.2 Cable Assemblies are low-loss triple-shielded cables that provide an ideal combination of low attenuation and VSWR/loss/phase stability. These cable assemblies feature a ProJack protective jacket that offers a high armor level for defense systems. The black PU jacket, stainless steel braid, and stainless steel spring make ProJack suitable for harsh environments. These cable assemblies are fire resistant and operate at -55°C to +105°C temperature range. Radiall TestPro 4.2 uses a solid silver-platted copper-clad steel center conductor, aluminum-polyimide tape as an interlayer and an SPC outer layer. These cable assemblies are compatible with SMA series, PC7 series, N series, and TNC series connectors. The TestPro 4.2 cable assemblies feature >,2300N/100mm crush resistance, phase and loss stability with flexure, and longer calibration intervals. These cable assemblies are ideal for use in test labs, production floor testing, thermal vacuum chambers, nearfield scanners, and anechoic chambers.
