SFL™ (Spiral Flex) Coaxial Cable
Harbour’s SFL Spiral Flex™ coaxial cables, more flexible and supple versions of the industry standard SS Spiral Strip constructions, have been designed with a specially formulated polyurethane jacket compound and stranded silver plated copper and copperweld center conductors. These 50 ohm versions exhibit VSWR levels that meet or exceed similar size flexible constructions, and just like their SS cable counterparts, offer excellent shielding effectiveness with readily available connectors.
The solid light blue polyurethane jackets offer excellent braid-to-jacket adhesion and electrical stability during usage. The polyurethane jackets also provide excellent cut-through, tear, and abrasion performance combined with resistance to chemicals.
Although the insertion loss is slightly higher than their SS cable counterparts, SFL attenuation levels through 18 GHz are substantially lower than comparable MIL-DTL-17 constructions.
