HH85295F - 50 Ohm High Frequency RF Cable

HH85295F is a 50-Ohm microwave coaxial cable designed for high-frequency applications on the Ku band and X band. HH85295F provides superior signal integrity, low insertion loss, less RF interference, and a robust yet easy-to-install design. The HH85295F coaxial cable is a 100% shielded construction, incorporating a flat spiral-wrapped shield that achieves -110 dB shielding effectiveness, the same as a solid copper tube. The inner spiral shield conforms to the low-loss PTFE dielectric for superior uniformity and stability of all operation parameters, initially and over time.
