Gold‑plated phosphor‑bronze spring contacts mate with the inner conductors of coaxial cables for RF high‑frequency signal transmission.
The gold‑plating prevents oxidation and delivers low impedance, compatible with high‑frequencies up to 56 GHz.
This ultra‑fine RG1.13 cable features Teflon insulation with 7‑strand twisted conductors, foamed PE / PTFE dielectric to maintain a constant 50 Ω characteristic impedance.
It adopts double‑layer shielding: full‑coverage inner aluminum‑foil plus outer high‑density copper‑braid, which acts as the RF ground‑wire and is crimped conductive with the IPEX connector shell to suppress signal interference.
This cable is used for:
1. Built‑in FPC flexible antennas (laptops, routers and smart devices)
2. Ceramic‑GPS dielectric antennas (vehicle T‑BOX and positioning terminals)
3. External rubber‑rod antennas (gateways, DTUs and industrial‑control boxes)
