    Semi-Rigid Coaxial Cable
    　
    Micro-Coax semi-rigid cable is still the best pure microwave transmission medium available in the world. The solid tubular outer conductor yields 100% RF shielding and enables the dielectric and center conductor to remain precisely spaced. This results in optimum impedance control as well as the lowest possible insertion loss and weight to size ratios. Semi-rigid cables are also inexpensive to purchase when compared to many other coaxial cable alternatives. The primary considerations for using semi-rigid are the availability of bend tooling, the difficulty in routing and the need to reform the cable. Generally, the more flexibility required, the more the designer should consider other alternatives. However, for pure microwave performance semi-rigid can't be beat.

    Please select from the choices below:

    * Low Loss cables employ a low density PTFE dielectric for improved insertion loss, electrical phase stability and increased temperature range.
    ** MIL-C-17 cables are on the MIL-C-17 qualified products list (QPL) having passed all of the qualifications and acceptance requirements of MIL-C-17.
    *** Aluminum jacked cables, which are typically tin-plated for solderability enable repeated bending and hand forming. They are excellent choices when the performance of semi-rigid is required, together with flexibility to hand-form in place.
