Introduction
Starlink’s “High Performance” line represents the top-tier of SpaceX’s satellite internet hardware — designed for users who demand durability, higher throughput consistency, and reliability in harsh or mobile environments.
But as the lineup evolves, there’s confusion over how many versions actually exist. In short: there are two major versions of the High Performance dish — the Flat High Performance (FHP) and the newer Performance Gen 3, which effectively replaces it.
This article breaks down their dimensions, weight, power draw, environmental ratings, and key physical differences, complete with reference images and mounting insights.
Version 1: Starlink Flat High Performance (FHP) Dish
Overview
The Flat High Performance (FHP) dish was Starlink’s first “pro-grade” unit aimed at business, RV, marine, and other demanding installations. Unlike the standard residential dish with a motorized stand, the FHP model features a fixed, low-profile panel that’s better suited for rooftop or vehicle mounting.
Key Specifications
| Feature | Details |
|---|---|
| Footprint | 575 mm × 400 mm (≈ 22.6″ × 15.7″) |
| Thickness | ~40 mm (1.6″) |
| Weight | ~5.9 kg (13 lbs) without cable / ~8.1 kg (17.9 lbs) with 25 m cable |
| Field of View | 140° |
| Environmental Rating | IP56 |
| Operating Temperature | –30 °C to +50 °C (–22 °F to 122 °F) |
| Power Consumption | 110 – 150 W (avg.) |
| Snow Melt Capacity | Up to 75 mm (3″) per hour |
| Wind Resistance | > 280 km/h (174 mph) |
| Mounting | 4 × ¼-20 bolts (mount plate compatible) |
Real-World Notes
-
The FHP dish’s flat design allows it to sit nearly flush on a surface, making it ideal for low-clearance setups like RVs or boat decks.
-
It offers a wider field of view (140°) than the standard dish, enabling better performance in partially obstructed areas.
-
However, its higher power draw and limited portability make it better suited for fixed installations rather than plug-and-play residential use.

Version 2: Starlink Performance (Gen 3) Dish
Overview
The Performance Gen 3 dish is Starlink’s latest and most advanced iteration of the High Performance family. It retains the same wide 140° field of view as the FHP but introduces a smaller, lighter, and more durable design.
It is now rated IP69K, meaning it can withstand high-pressure water jets and extreme dust — a leap forward for off-road, marine, and industrial environments.
Key Specifications
| Feature | Details |
|---|---|
| Footprint | 594 – 610 mm × 383 – 397 mm (≈ 23.4″ – 24″ × 15″ – 15.6″) |
| Thickness | ~39 – 41 mm (1.5 – 1.6″) |
| Weight | Slightly lighter than FHP (~12 lbs range) |
| Field of View | 140° (unchanged) |
| Environmental Rating | IP69K |
| Power Consumption | Comparable to FHP, slightly reduced at idle |
| Operating Temperature | –30 °C to +50 °C (–22 °F to 122 °F) |
| Wind Resistance | > 280 km/h (174 mph) |
| Mounting | Updated bolt pattern for Gen 3 mounting kits |
Real-World Improvements
-
More compact and rugged: The Performance Gen 3 dish shaves off some size while improving weatherproofing.
-
Higher IP rating: IP69K certification means full protection against dust, rain, and even pressure-washing.
-
Future-ready hardware: Built to handle Starlink’s upcoming satellite generations that aim for gigabit-class performance.
-
Enhanced installation flexibility: Compatible with newer in-motion and high-vibration mounts.

| Power Consumption | 110–150 W | 100–140 W |
| Best Use Case | Fixed or mobile installations with mild weather | Extreme-condition or future-proof deployments |
How Many Versions Exist?
Despite internet rumors of a “third” or “enterprise” High Performance dish, official data confirms only two versions of the High Performance platform have been released to date:
-
The Flat High Performance (original version)
-
The Performance Gen 3 (current version, successor)
The so-called “Enterprise” or “Commercial” dishes use similar technology but belong to a separate category targeting large-scale business deployments, not the High Performance line directly.
Which Should You Choose?
-
Flat High Performance (FHP)
Ideal for existing mobile or remote installations that already have compatible mounts or where IP56 protection is sufficient. -
Performance Gen 3
The better option for new installs or upgrades where maximum durability, future compatibility, and harsh-weather operation are priorities.
Both provide identical satellite tracking performance (140° FoV), but the Gen 3’s improved housing, slightly lower power draw, and higher ingress protection make it the most versatile long-term choice.
Conclusion
For Starlink users pushing the limits — whether in off-grid setups, overland rigs, marine vessels, or enterprise networks — the High Performance line remains the gold standard.
There are only two genuine versions:
-
Flat High Performance – the original workhorse built for stability and flexibility.
-
Performance Gen 3 – the refined successor with higher environmental resilience and future-proof hardware.
