The High-Gain Antenna Project in ARC Raiders is a three-stage construction objective introduced with the Flashpoint update. Progression is entirely material-driven, with each phase requiring specific ARC components—some of which only drop under limited map conditions.
1. How the High-Gain Antenna Project Works
The High-Gain Antenna is a multi-stage construction project tied to Flashpoint content. Each stage requires submitting a fixed set of ARC materials gathered during raids, with later phases introducing rare drops that only appear under certain map conditions. After collecting materials during a raid, you need to go to the Raider>Projects to submit all the materials manually.
2. All High-Gain Antenna Project Materials and Rewards

The High-Gain Antenna Project spans three stages, with each phase unlocking a fixed set of gear, attachments, and Raider Tokens. Rewards are distributed per stage, and there is no additional bonus for full completion. Across all stages, the project delivers a fully kitted weapon setup, multiple high-tier attachments, utility items, and a total of 500 Raider Tokens.
2.1. Stage 1 – Sturdy Base
High-Gain Antenna Stage 1
The opening stage already demands a solid amount of ARC materials, mostly from high-tier enemies and ARC probes. Larger ARC units and probe loot are the most reliable sources here, making combat-heavy routes more efficient than passive scavenging.
| Stage | Project Requirement | Best Locations to Farm | Project Rewards |
|---|---|---|---|
| Stage 1 – Sturdy Base | 25 × ARC Alloys 10 × ARC Flex Rubbers 10 × ARC Performance Steels 15 × Advanced ARC Powercells |
High-tier ARC zones Areas with Bastions, Sentinels, Bombardiers ARC Probe farming routes |
Torrente II Extended Medium Mag III Extended Barrel Padded Stock |
2.2. Stage 2 – Data Logger
This stage introduces the first hard gate, requiring materials tied to the Close Scrutiny condition. Vaporizer Regulators and Assessor Matrixes can be farmed during Close Scrutiny, making this stage entirely dependent on that map condition rotation.
| Stage | Project Requirement | Best Locations to Farm | Project Rewards |
|---|---|---|---|
| Stage 2 – Data Logger | 15 × ARC Coolants 15 × ARC Thermo Linings 4 × Vaporizer Regulators 6 × Assessor Matrixes |
Close Scrutiny raids Assessor encounter zones Drone-heavy areas with Vaporizer spawns |
Bobcat III Extended Light Mag III Vertical Grip III 100 Raider Tokens |
2.3. Stage 3 – Parabolic Dish
The final stage significantly increases the requirements and continues to rely on the same rare materials, alongside Surveyor drops.
| Stage | Project Requirement | Best Locations to Farm | Project Rewards |
|---|---|---|---|
| Stage 3 – Parabolic Dish | 10 × Surveyor Vaults 20 × ARC Synthetic Resins 15 × Vaporizer Regulators 18 × Assessor Matrixes |
Close Scrutiny for Regulators and Matrixes Open zones with Surveyor spawns High-density ARC areas for Resin |
Vita Spray Photoelectric Cloak Snap Hook 400 Raider Tokens |
3. Tips for Completing the High-Gain Antenna Project
Close Scrutiny map condition
- Prioritize Close Scrutiny runs to secure Vaporizer Regulators and Assessor Matrixes early
- Queue in Solos for PvE-friendly lobbies and work together to secure the Dolabra blueprint and materials
- Target Assessor encounters for multi-material efficiency
- Engage Surveyors whenever possible instead of delaying their farming
- Treat ARC Synthetic Resin as passive loot gathered across all runs
- Track resources to avoid selling rare project materials, as they are reused across stages
- Extract safely by using the safe pockets when carrying late-stage materials to prevent unnecessary losses
