General Cable Specifications
| Specification | Details |
|---|---|
| Length Tolerance (6-119) | -0", +0.5" |
| Length Tolerance (120-179) | -0", +1" |
| Length Tolerance (180-480) | -0", +4" |
| Minimum Bend Radius | Varies by series (e.g., 0.6" for HP120S, 2.2" for KW430) |
| Operating Temperature | Varies by series (e.g., -65/+200C for HP Series, -65/85C for KW Series) |
| Insertion Loss Calculation | IL = Cable Loss + Connector Loss; Cable Loss = L x [(k1 x F) + (k2 x F)] / 1200; Connector Loss = k3 x F |
| VSWR | Typically 1.15:1 to 1.50:1 depending on interface and frequency (refer to specific series for details) |
