SRC SteelFlex® Low Loss Flexible Coax

SteelFlex low loss flexible coax

We developed this cable to be a flexible alternative to standard 085 coax (RG405) and 141 coax (RG402) semi rigid coax. Using proven off-the-shelf semi rigid direct soldered connectors makes these assemblies cost effective. The connector ends have custom, armorized metal boots and heavy-duty PVC shrink that make the solder joints extremely durable. SteelFlex is an excellent choice for tactical or electronic warfare applications or for higher frequency test cables and detachable interconnects that demand low attenuation in an affordable low loss flexible coax cable.

SRC SteelFlex 50 Ohm cables are assembled to your specs and available with your markings. This versatile flexible cable is right when you need a coaxial cable that must be phase stable, withstand multiple flexures, provide greater power handling capability, exhibit low attenuation comparable to semi rigid and have shielding above 100dB. SteelFlex is designed to offer a good bend radius, angle of flex and stable electrical properties after multiple flexures. It may be armorized and can be configured with a very wide choice of connectors, depending upon the frequency of your application, including: MCX, MMCX, SMA, SMB, SMC, SSMA, SSMB, SSMC, TNC, N, 3.5mm, GPO (SMP), GPPO (SSMP), 2.9mm (K), 2.4mm and 1.85mm (V).
