To ensure proper field installation and termination, crimp die sets are available for the connectors. In addition, PIC Wire & Cable offers complete certified cable assemblies to streamline the installation process. The connectors also improve termination, installation, maintenance and reliability. Pairing RFMATES ULTRALITE cables and connectors provides a robust interconnect solution by optimizing electrical performance and increases weight savings.

The RFMATES ULTRALITE family includes a variety of matching connectors, including a full line of M39012 style RF connectors. Each cable is also laser markable to streamline and simplify the labeling process. They are chemical resistant, abrasion resistant, and meet the FAA flammability requirements 14 CFR Part 25.869 (a)(4) Amdt 25-113 Appendix F Part 1 (a)(3). This material allows cables to be used and stored in high temperature environments. RFMATES ULTRALITE jackets are made of high temperature, white ethylene tetrafluoroethylene (ETFE). This braid is designed to minimize dB loss and its lightweight material contributes to weight savings. RFMATES ULTRALITE cables use a Silver Plated Copper Clad Aluminum (SPCCA) outer braid. This shield design increases the cable’s shielding effectiveness and lowers its dB loss. The spiral wrapped shield provides 100% coverage compared to flat braided shields. This is significantly higher than the standard -75 dB for dual braided shields used in RG cables, and -90 dB for cables with a foil and outer braid shield. With this design, the -110 dB shielding effectiveness is the same as a semi-rigid coaxial cable (solid copper tube), such as RG405. RFMATES ULTRALITE cables use a Silver Plated Copper spiral (helically) wrapped shield.

This dielectric also saves weight and increases flexibility. The dielectrics have a high Velocity of Propagation (VoP) which lowers the cable’s insertion (dB) loss, while still maintaining a strong composition. RFMATES ULTRALITE cables use either an expanded extruded Polytetrafluoroethylene (PTFE) or tape wrapped PTFE dielectric. Steel conductors are 11% lighter compared to copper conductors of the same gauge. Based on its size, UH44193 uses a Silver Plated Copper Clad Steel. SPCCA conductors are 69% lighter compared to copper conductors of the same gauge. UH67163, UH25107 and UH22089 use a Silver Plated Copper Clad Aluminum (SPCCA) conductor to increase weight savings. Choosing RFMATES ULTRALITE cables reduced the helicopter’s cable weight by 51% and saved 30.24 pounds. To reduce weight, RFMATES ULTRALITE cables were installed on the airframe and weighed only 28.82 pounds. Each helicopter used 809.1 feet of coax cable, and the manufacturer needed to reduce some of the 59.06 pounds of cable on the airframe. Table 1: RFMATES ULTRALITE and RG Cable Comparison 50% Cable Weight Saved on HelicopterĪ leading helicopter manufacturer asked PIC Wire & Cable to help find a solution to reduce coax cable weight on one of its airframes. These lightweight, flexible cables offer significant weight savings over competitor and RG cables: The RFMATES ULTRALITE family has been rapidly adopted by major aircraft and avionics OEMs in response to the rising industry demand for weight saving cables.
