Quick Answer / Summary: Gen 2 Starlink features a motorized rectangular phased-array dish measuring 513 x 303 mm (20.2 x 11.9 in) and weighing 4.2 kg. It connects via a 75-foot proprietary waterproof cable to a Wi-Fi 5 router. Crucially, connecting third-party enterprise firewalls requires purchasing Starlink’s proprietary Ethernet Adapter and enabling Bypass Mode.
The Gen 2 Starlink user terminal (often called the ‘Standard Actuated’ or ‘Rectangular Dish’) represents the most widely deployed consumer hardware in Starlink history. Replacing the original heavy round Gen 1 terminal, Gen 2 introduced a compact, lightweight rectangular form factor, optimized power draw, and a sleek indoor Wi-Fi router.
Hardware Redesign: Rectangular Form Factor vs. Round Gen 1
SpaceX designed Gen 2 to reduce manufacturing costs and shipping volume. The dish was streamlined from a 23-inch circular dish to a 20.2 x 11.9 inch rectangular surface. Internal electronics were integrated onto automated surface-mount assemblies, reducing overall terminal weight by over 40% and power consumption to roughly 50W to 75W.
The Proprietary SPX Connector Dilemma
Unlike Gen 1, which used standard RJ45 Ethernet ports, Gen 2 introduced proprietary waterproof push-in SPX connectors on both ends of the 75-foot cable. The Gen 2 router omitted built-in RJ45 LAN ports, forcing users who need hardwired Ethernet to buy an external Starlink Ethernet Adapter.
Router Bypass Mode and Third-Party Firewall Integration
To integrate Gen 2 Starlink into an enterprise corporate network or whole-home mesh Wi-Fi system, users connect the Ethernet Adapter and enable ‘Bypass Mode’ in the Starlink mobile app. This disables the internal Wi-Fi radios and NAT routing, passing a public WAN IP directly to third-party routers (such as pfSense, UniFi, or ASUS).
Mounting Ecosystem and Cable Routing
Gen 2 utilizes a quick-connect mast compatible with diverse factory mounts: Pivot Mount for pitched roofs, Pipe Adapter for existing satellite J-poles, and Flashing Mounts for asphalt shingles, requiring a 3/4-inch (19mm) hole to route the proprietary cable through exterior walls.
Gen 1 (Round) vs Gen 2 (Rectangular) Starlink Hardware
| Specification Parameter | Gen 1 (Round Dish) | Gen 2 (Rectangular Actuated) | User Impact |
|---|
| Dish Dimensions | 589 mm (23.2 in) Diameter | 513 x 303 mm (20.2 x 11.9 in) | Gen 2 is much easier to transport & mount |
| Terminal Weight | 7.3 kg (16.0 lbs) | 4.2 kg (9.2 lbs) | Gen 2 significantly lighter on roof mounts |
| Cable Type | Standard Shielded CAT5e (Fixed) | 75ft Detachable Proprietary SPX | Detachable cable allows easy replacement |
| Built-in Ethernet Port | Yes (RJ45 Port on Router) | No (Requires External Adapter) | Gen 2 requires $25 adapter for LAN cable |
| Average Power Draw | 90W – 120W | 50W – 75W | Gen 2 is significantly more energy efficient |
| Wi-Fi Generation | Wi-Fi 5 (802.11ac) | Wi-Fi 5 Dual-Band 3×3 MIMO | Both provide solid indoor wireless reach |
Real-World Application Scenarios
Residential suburban and rural home internet, off-grid cabins, mobile RV camping setups, and light commercial office connectivity.

Frequently Asked Questions (FAQ)
Q: Can I splice the Gen 2 proprietary cable to make it longer?
A: While third-party SPX-to-RJ45 adapter pigtails exist to extend runs over pure copper CAT6, SpaceX offers official 150-foot replacement cables to avoid signal degradation.
Q: Does the Gen 2 dish still move automatically?
A: Yes, Gen 2 contains internal stepper motors that tilt and rotate the dish during initial setup to point toward the optimal satellite orbital track.
