CM-COAX-PS-UF
Ultra-Flexible Phase-Stable Coaxial Cables
Available for project supply. Select a model below and confirm the order specification.
Catalogue data for available cable configurations. Final tolerances and acceptance requirements are agreed for the selected model.
Typical attenuation at +25 °C and sea level. Repeated-flex acceptance requires an agreed bend radius, cycle method, frequency and phase/loss limits. No universal cycle-life rating is stated here.
