The Arc Raiders High Gain Antenna Project is one of the most rewarding — and most demanding — player projects introduced since the game launched in October 2025. Added as part of the Flashpoint update (Patch 1.22.0) on March 31, 2026, this three-stage construction project tasks you with gathering rare ARC components and donating them at your workbench to help Celeste and Shani build a parabolic antenna array across the Rust Belt.
The payoff? A fully kitted weapon setup, high-tier attachments, a legendary Snap Hook, a Photoelectric Cloak, and 500 Raider Tokens in total. But the grind to get there — especially through Stage 2 and Stage 3 — is no joke. This guide covers every material requirement, every reward, where to farm the trickiest items, and the most efficient strategies for completing all three stages before the next update cycle.
Heads Up (April 2026): With the ARC Raiders Riven Tides update confirmed for April 28, 2026, time is running short to complete the High-Gain Antenna Project during the Flashpoint window. Don’t sit on this one.
What Is the High Gain Antenna Project?
The High-Gain Antenna is a multi-stage player project found under the Projects section of the Raider tab in Speranza. It works like the earlier Trophy Display and Weather Monitor System projects — you donate specific ARC materials to a workbench, and the project advances stage by stage, rewarding you at the completion of each phase.
Unlike crafting, where you build items for your own use, this project is about contributing components toward a larger in-world goal: giving Celeste and Shani a long-range signal array to monitor the mysterious ARC transmissions linked to hurricane activity and aerial threats. When placed in open areas, these parabolic dishes can form an array capable of detecting ARC signals across a narrow beamwidth — and Shani believes they may help triangulate the origin of the disturbing signals recently reported across the Rust Belt.
Key details at a glance:
- Launched: March 31, 2026 (Flashpoint update / Patch 1.22.0)
- Stages: 3 (Sturdy Base → Data Logger → Parabolic Dish)
- Rewards distributed: Per stage — not as a lump sum at the end
- Total Raider Tokens: 500 across all stages
- No scheduled end date (but expected to conclude when Riven Tides launches April 28, 2026)
All High Gain Antenna Project Stages, Materials & Rewards
Stage 1 — Sturdy Base
Stage 1 is the most approachable phase. If you have been playing ARC Raiders since launch, there is a reasonable chance you have most of these materials sitting in your stash already.
Required Materials:
| Material | Quantity Required |
|---|---|
| ARC Alloy | 50 |
| ARC Flex Rubber | 10 |
| ARC Performance Steel | 10 |
| Advanced ARC Powercells | 15 |
Stage 1 Rewards:
- Bobcat (Level 3)
- Extended Light Mag (Level 3)
- Vertical Grip (Level 3)
- 100 Raider Tokens
Where to find Stage 1 materials: Standard ARC enemies are your best source here. Larger ARC units — Bastions, Surveyors, and ARC Probes — drop Alloy, Flex Rubber, and Performance Steel regularly. Advanced ARC Powercells are slightly more targeted, but breaching Probes and looting Couriers will fill this requirement over a few focused sessions. No special map condition is required for Stage 1, which makes it the most straightforward farming phase of the entire project.
Stage 2 — Data Logger
Stage 2 is where the High-Gain Antenna Project starts requiring Flashpoint-specific content. Two of the four materials only appear under the Close Scrutiny map condition, meaning standard raiding sessions will not cut it here.
Required Materials:
| Material | Quantity Required |
|---|---|
| ARC Coolant | 15 |
| ARC Thermo Lining | 15 |
| Vaporizer Regulator | 4 |
| Assessor Matrix | 6 |
Stage 2 Rewards:
- Torrente weapon blueprint
- Rare weapon attachments
- 100 Raider Tokens
Where to find Stage 2 materials: ARC Coolant and ARC Thermo Lining drop from ARC enemies under Close Scrutiny, particularly from Assessors and Surveyors. For Vaporizer Regulators, you need to hunt and kill Vaporizers — the new aerial drone enemies that only spawn during Close Scrutiny. For Assessor Matrices, you need to breach the Assessor drop pods that land during Close Scrutiny.
The relatively low quantities in Stage 2 (just 4 Vaporizer Regulators and 6 Assessor Matrices) make this manageable if you approach it efficiently. Check your stash first to avoid farming materials you already have.
Stage 3 — Parabolic Dish
Stage 3 is the real investment. Material requirements spike significantly, and all four items require active engagement with Close Scrutiny or map-specific objectives. This is where many players stall.
Required Materials:
| Material | Quantity Required |
|---|---|
| Surveyor Vaults (looted) | 10 |
| ARC Synthetic Resin | 20 |
| Vaporizer Regulator | 15 |
| Assessor Matrix | 18 |
Stage 3 Rewards:
- Vita Spray
- Snap Hook (Legendary)
- Photoelectric Cloak
- 300 Raider Tokens
Where to find Stage 3 materials: Surveyor Vaults come from breaching Surveyors on the map — these are tankier than standard ARC units and require dedicated firepower. ARC Synthetic Resin drops from Shredders, newly escaped from Stella Montis with the Flashpoint update, and is deceptively slow to accumulate. The Vaporizer Regulator and Assessor Matrix requirements are dramatically higher than Stage 2, meaning you will need multiple dedicated Close Scrutiny sessions to fill these slots.
The Snap Hook (legendary rarity) is the standout reward, and the 300 Raider Tokens in Stage 3 alone make this phase worth completing even if the earlier stages felt underwhelming. Do not skip it.
How to Farm Vaporizer Regulators
The Vaporizer Regulator is one of the two most in-demand materials in the High-Gain Antenna Project — and farming enough of them across Stage 2 and Stage 3 (19 total) requires a focused, methodical approach.
Vaporizers do not spawn in standard raids. They appear exclusively during the Close Scrutiny map condition, which can occur on four of the five current maps:
- Dam Battlegrounds
- Buried City
- Spaceport
- Blue Gate
Stella Montis is excluded because its indoor layout does not support the Assessor’s open-air landing mechanics.
Step-by-step farming loop:
- Check your world map for the Close Scrutiny icon before queuing. It rotates on a schedule and is always active on at least one map at any given time.
- Load into a Close Scrutiny session on one of the four eligible maps with your best anti-ARC loadout.
- Wait a few minutes for Assessor probes to begin landing — watch for three large red beams shooting vertically into the sky.
- Follow the beams to the Assessor landing zone. Vaporizers will be circling the probe in groups of two or more.
- Kill Vaporizers and loot each destroyed fragment — every Vaporizer guarantees at least one Vaporizer Regulator drop, along with other rare crafting resources.
- Extract immediately with your loot. Do not over-farm in a single session if your inventory is full.

How to Farm Assessor Matrices
The Assessor Matrix is the other rare material required for Stages 2 and 3, and it is arguably harder to farm efficiently than the Vaporizer Regulator. Across both stages, you need 24 Assessor Matrices total — a significant ask.
Assessor Matrices come from one source only: breaching the Assessor drop pods during the Close Scrutiny map condition. These three-legged ARC probes begin landing a few minutes into each Close Scrutiny session and emit red beams of light that make them easy to track. Each Assessor has three separate containers you can breach by approaching the legs once the platform fans out.
Critical farming tips for Assessor Matrices:
- Speed is everything. Assessors do not wait — if you take too long, the pod launches back into the sky, taking all loot with it.
- Bring armor-penetrating weapons. The Hullcracker and Aphelion are consistently recommended by the community for Close Scrutiny runs. Vaporizers — the Assessor’s main guards — have heavy armor and require serious firepower.
- Do not fight everything. Engaging Vaporizers in a prolonged firefight burns through your healing and ammunition. Breach the Assessor quickly, loot the containers, and disengage.
- Other players are competing for the same pods. Once red beams appear on the horizon, you will not be the only squad moving toward them. Prioritize speed over stealth when heading to an Assessor.
- The Dolabra Blueprint can also drop from Assessors. If the legendary shotgun is on your wishlist, keep an eye out during your Matrix farming sessions.
The Assessor Matrix is also recyclable: breaking down one Matrix gives you 3 Advanced ARC Powercells and 1 Advanced Mechanical Component — useful if you accidentally overflow on Matrices before Stage 2 is complete.
High Gain Antenna Project Rewards — Full Summary
Here is a consolidated view of everything you earn across all three stages:
| Stage | Key Rewards | Raider Tokens |
|---|---|---|
| Stage 1 — Sturdy Base | Bobcat (Lv. 3), Extended Light Mag (Lv. 3), Vertical Grip (Lv. 3) | 100 |
| Stage 2 — Data Logger | Torrente blueprint, Rare attachments | 100 |
| Stage 3 — Parabolic Dish | Vita Spray, Snap Hook (Legendary), Photoelectric Cloak | 300 |
| Total | Full weapon setup + legendary gadgets | 500 |
The 500 total Raider Tokens alone justify completing the project from a pure value standpoint. Add the legendary Snap Hook and the Photoelectric Cloak — one of the game’s strongest utility items — and the High-Gain Antenna Project offers some of the best return on investment of any project in the Flashpoint meta.
Tips for Completing the Project Efficiently
Check your stash before farming. Stage 1 materials in particular tend to accumulate naturally through regular play. You may already have 30–40 ARC Alloy sitting unused before you even start.
Pre-farm Stage 2 and Stage 3 materials simultaneously. Both Vaporizer Regulators and Assessor Matrices are farmed from the same map condition (Close Scrutiny), often from the same location. Every Close Scrutiny run should be treated as progress toward both Stage 2 and Stage 3, regardless of which stage you are currently on.
Queue during peak hours for Close Scrutiny. More active lobbies mean more players engaging Assessors, which ironically can work in your favor — other squads drawing Vaporizer attention gives you a window to breach a pod while the fight is elsewhere.
Bring a coordinated squad. A three-person team makes Stage 2 and Stage 3 material farming significantly faster and safer. One or two players can hold back Vaporizers while the third breaches the Assessor. Solo runs are possible but substantially slower.
Use the Photoelectric Cloak to escape, not engage. If you are already a Stage 3 reward holder, the Cloak becomes your best extraction insurance — activate it the moment you loot an Assessor and move directly to extract.
Know your extraction routes before the pressure hits. On Close Scrutiny sessions, having your exit route planned before you start breaching Assessors is the difference between a full extract and an expensive death. Review our guide on how to extract in Arc Raiders to tighten up your escape game for these high-stakes runs.
Time Limit: Complete It Before Riven Tides
The High-Gain Antenna Project launched alongside Flashpoint on March 31, 2026. Based on the pattern set by the previous Weather Monitor System project — which ended when the Flashpoint update went live — the High-Gain Antenna Project is expected to conclude when the next major update arrives.
The ARC Raiders Riven Tides update is confirmed for April 28, 2026, bringing a new coastal map, a new large ARC enemy type, and the third Expedition window. Treat this date as the effective project deadline. That gives you until April 28 to complete all three stages — roughly one week from the time of writing.
Stage 3 requires 18 Assessor Matrices and 15 Vaporizer Regulators. If you have not started yet, prioritize Close Scrutiny sessions immediately and do not waste sessions on standard raiding.
Frequently Asked Questions
Can I work on all three stages simultaneously? No. Each stage must be completed before the next one unlocks. However, you can pre-farm materials for later stages and store them in your stash ahead of time — which is strongly recommended from Day 1.
Does the High-Gain Antenna Project have a time limit? There is no officially announced end date, but community speculation and the pattern from previous projects strongly suggests it will end when Riven Tides launches on April 28, 2026.
Can I get Assessor Matrices outside of Close Scrutiny? No. Assessor Matrices are exclusively sourced from Assessor drop pods during the Close Scrutiny map condition. There is no alternative farming method.
Can I get Vaporizer Regulators from ARC Couriers? ARC Couriers have been cited as an extremely low-probability secondary source, but Close Scrutiny is the only reliable farming method. Do not build your farming loop around Courier drops.
What if I run out of time before completing Stage 3? Stage 1 and Stage 2 rewards are granted upon their respective completions — you keep everything earned from completed stages even if Stage 3 is unavailable after the project ends.
Is the project worth it for solo players? Yes, but expect a longer grind. Solo Close Scrutiny runs are viable, and some players find a stealth approach — breaching Assessors while avoiding Vaporizers rather than fighting them — to be more consistent than aggressive combat solo.
Conclusion
The Arc Raiders High Gain Antenna Project is one of the most rewarding content pursuits in the Flashpoint update, but it demands real time investment — especially in the Close Scrutiny map condition. Stage 1 is approachable for anyone with a stash of standard ARC materials. Stage 2 and Stage 3 require deliberate farming of Vaporizer Regulators and Assessor Matrices, both of which are gated behind Close Scrutiny and the specific enemies that spawn within it.
With the Riven Tides update landing April 28, 2026, the window to complete all three stages is closing fast. Use this guide as your roadmap, pre-farm every Close Scrutiny session, and extract clean.
