The Flashpoint update has added a new long-term grind to ARC Raiders, and the High-Gain Antenna project is at the heart of it. On paper, it seems easy because there are only three stages, but the number of rare materials and specific enemies makes it one of the hardest projects in the game right now.
Hunting Vaporizers, farming Assessors, and running the right map conditions are the hardest parts. Here’s a full list of everything you need, where to find it, and how to finish the project without wasting time..
How to Complete ARC Raiders High-Gain Antenna Project

Go to the Raiders tab and click on the Projects link. You can find the High-Gain Antenna project here, along with other goals that are still in progress.
ARC Raiders High-Gain Antenna requirements:
- Sturdy Base
- Data Logger
- Parabolic Dish
You can’t get rewards until you’ve fully submitted all four materials for each stage. You can’t claim anything in the middle, so it’s important to finish each section in one go.
There is no set end date yet, but past projects have ended without warning. It makes sense to start grinding now instead of waiting.
Sturdy Base Requirements And Farming Locations

The first stage is easy and focuses on basic ARC materials that drop from normal enemies.
Requirements:
- 50 ARC Alloy
- 10 ARC Flex Rubber
- 10 ARC Performance Steel
- 15 Advanced ARC Powercell
Where To Find Them:
Farming ARC Alloy is the easiest. Most ARC enemies drop it, so if you raid a lot, you’ll get a lot of it.
You can get ARC Flex Rubber and ARC Performance Steel from tougher enemies like Bastions, Leapers, and Sentinels. To move faster, focus on high-level ARC encounters or loot ARC Probes.
Bigger enemies like Rocketeers, Comets, and Bastions drop Advanced ARC Powercells. These happen a lot in the middle to late stages of a raid.
Rewards:
- Torrente II
- Extended Medium Mag III
- Extended Barrel
- Padded Stock
This stage is mostly about consistent farming rather than difficulty.

This is when the project really starts to get serious. You now need materials that are related to the Close Scrutiny map condition.
Requirements:
- 15 ARC Coolant
- 15 ARC Thermo Lining
- 4 Vaporizer Regulator
- 6 Assessor Matrix
Where To Find Them:
Fireballs, Comets, and Wasps are mid-level ARC enemies that drop ARC Coolant and Thermo Lining. These are not too hard to farm.
The real problem is the vaporizer regulators. They only drop from Vaporizers, a new flying enemy that was added in the Flashpoint update. These machines appear during Close Scrutiny and are much harder to beat than regular ARC units.
Assessor Matrixes come from looting Assessors, which are also found in the same map condition. Each Assessor gives out several loot panels, so always try to get to them as soon as possible.
Vaporizer Tips:
- First, aim for the rotors to slow down.
- For the most damage, shoot the core from below.
- Don’t waste bullets during the shield phase.
- To hide from the laser, hide behind buildings.
Rewards:
- Bobcat III
- Extended Light Mag III
- Vertical Grip III
- 100 Raider Tokens
This stage is where most players get stuck due to the Vaporizer grind.
Parabolic Dish Requirements And Late-Game Farming

The last stage makes the grind even harder, especially when you do the ARC Raiders Assessor Matrix farm.
Requirements:
- 10 Surveyor Vault
- 20 ARC Synthetic Resin
- 15 Vaporizer Regulator
- 18 Assessor Matrix
Where To Find Them:
Surveyors can drop Surveyor Vaults, which can show up on more than one map. They aren’t aggressive, but they do tend to run away, so act quickly when you see one.
You can get ARC Synthetic Resin from mid-level ARC enemies like Wasps, Snitches, and Shredders. Baron Husks is another place where you can find it.
The same method is used for vaporizer regulators and assessor matrices as it is for Stage 2. This time, the amount is much higher, so Close Scrutiny runs are almost required.
The amount of cover in Buried City makes it one of the best places to fight Vaporizers.
Rewards:
- Vita Spray
- Photoelectric Cloak
- Snap Hook
- 400 Raider Tokens
Once this stage is complete, the project is done. There is no extra final reward, but the stage rewards are already strong enough. That’s all from us regarding ARC Raiders High-Gain Antenna Project.
Best Farming Strategy For Faster Completion

The most efficient way to complete the High-Gain Antenna project is to focus heavily on the Close Scrutiny map condition.
This mode increases ARC spawns and introduces both Vaporizers and Assessors, which are required for later stages.
Run with proper gear, especially high-damage weapons, since Vaporizers are not easy fights. Solo runs are possible, but teaming up makes a noticeable difference in survival and speed.
Also, start collecting materials for later stages early. Even though the game hides future requirements at first, storing items like Assessor Matrix and Regulators will save a lot of time later.
