About the bending radius of VNA Test Cable

Every VNA Test Cable has a maximum bend radius, beyond which it will first make the measurement inaccurate and eventually damage the VNA Test Cable. Although in some cases a greater degree of bending may seem unavoidable, even in this case it should be avoided as a mistake can result in damage to the entire VNA Test Cable Assembly . That said, bending the VNA Test Cable to the maximum bend radius should be avoided under all circumstances.

In addition, twisting of the VNA Test Cable should also be avoided, because twisting may cause damage to the VNA Test Cable, damage to the integrity of the components, and sometimes damage to the connector. Wrinkles or other signs of stress in the jacket of the VNA Test Cable indicate that the VNA Test Cable has been severely twisted or has exceeded its bend radius rating.

VNA Test Cable jackets are available in a variety of materials, each with its own advantages and disadvantages in harsh environments. For example, polyurethane is resistant to solvents, UV light, radiation, and fungi, but not cleaning chemicals. Fluoropolymers such as fluorinated ethylene propylene (FEP), perfluoroalkoxy (PFA), and polytetrafluoroethylene (PTFE) are well suited for these environments—they can withstand high temperatures and exposure to chemicals, acids, and aggressive solvents exposure and is a non-flammable substance.
