Starlink Gen 3 RJ45 Adapter Pair — Waterproof SPX to RJ45, 2 x 0.5 m Leads
Two short adapter leads for Starlink Gen 3. One plugs into the dish side, one into the router side. Each end gives you a waterproof RJ45 socket, so the long run in the middle can be a normal shielded Ethernet cable. If that middle cable ever gets damaged, you swap the middle cable, not the whole Starlink lead.
Starlink Gen 3 cables use a plug you cannot buy at a normal electronics shop. That gets awkward when the cable has to go through a wall, a conduit, or a long outdoor run. This pair fixes that. Each lead is about 0.5 m long. One end has the Gen 3 plug, the other end has a waterproof RJ45 female socket with a cap and a screw-on sealing shell. Plug one lead into the dish, one into the router, then join them with a shielded Ethernet cable of the length you need. Check the wiring before you power the system up — the source files do not state the pinout for this pair. The leads are built from 24 AWG CAT5e FTP cable with copper conductors, a ground wire, and Mylar plus foil shielding. The coupler shells are rated IP68 in the pictures, with silicone sealing rings. Keep the caps on any socket you are not using. What you get is a two-lead set. The long Ethernet cable between the two leads is not included — you supply it, cut to the length your route needs. One picture states a 175 ft maximum for that middle Ethernet run.

Compatibility
Fits Starlink Gen 3 / V3 Standard. It does not fit Gen 2 — the plug shape is different. One picture (the outdoor camping scene) also lists Gen 3 Mesh Router, Starlink Mini and Starlink Enterprise as compatible, but the source files do not say that. Treat Mini and Enterprise as unconfirmed until the supplier confirms it in writing.
Application scenarios
- Running a Gen 3 cable through a wall, conduit or cabinet where a fixed cable is hard to pull
- Replacing a damaged section without replacing the whole Starlink lead
- RV, boat and portable setups where the dish moves between sites
- Installer kits and service vans — the middle cable is easy to carry in different lengths
