Last Updated:12 May 2026

green_circle emoji Introduction

High Gain Antenna in ARC Raiders is a new player project added with the Flashpoint update. The project is tied to the new Close Scrutiny map condition and requires a large amount of ARC parts, including rare materials from new dangerous enemies. At first glance, the project looks short because it has only 3 stages, but in practice it can become one of the most annoying projects to farm because of Vaporizer Regulator and Assessor Matrix.

The source material describes High Gain Antenna as a project where players need to gather ARC materials, kill new ARC enemies, loot Surveyor Vaults, and run risky raids during Close Scrutiny. Completing the project rewards strong items: Torrente II, Bobcat III, rare and epic weapon attachments, Vita Spray, Photoelectric Cloak, Snap Hook, and 500 Raider Coins.

The main difficulty is not the number of stages, but the materials themselves. Some can be farmed from regular ARCs, but key items like Vaporizer Regulator and Assessor Matrix are tied to Close Scrutiny, where players must deal not only with dangerous ARCs but also with other Raiders. Because of that, High Gain Antenna quickly becomes a project about risk, PvP, survival, and proper preparation.

In this guide, we will cover:

  • what High Gain Antenna Project is;

  • how many stages the project has;

  • the full list of required materials;

  • where to farm ARC Alloy, ARC Flex Rubber, and ARC Performance Steel;

  • how to get Advanced ARC Powercell;

  • where to get ARC Coolant and ARC Thermo Lining;

  • how to farm Vaporizer Regulator;

  • where to get Assessor Matrix;

  • how to collect Surveyor Vaults and ARC Synthetic Resin;

  • what rewards High Gain Antenna gives;

  • how to complete the project faster;

yellow_circle emoji Quick Summary

High Gain Antenna has only 3 stages, but requires many valuable ARC parts. The first stage looks like regular material collection, the second introduces rare items from Close Scrutiny, and the third sharply increases the requirements, forcing players to actively farm Vaporizers, Assessors, Surveyors, Shredders, and other ARC sources.

purple_circle emoji What Is Close Scrutiny?

Close Scrutiny is the new map condition that drives the fastest High Gain Antenna progress. This is where players can consistently find new ARC materials, Vaporizers, and Assessors. If you want to complete the project quickly, this is the main route.

The source directly says that the short answer to “how to complete High Gain Antenna fast” is to farm the new Close Scrutiny map condition, because the required materials drop from the ARCs you fight during the event. This is also where Vaporizer Regulator and Assessor Matrix are available.

Other players also go for the same loot

Raid leader tip: Close Scrutiny is the best route, but not the safest one. Enter with proper gear or accept the risk of losing your loot.

red_circle emoji Stage 1 — Sturdy Base

The first stage is called Sturdy Base. It requires basic ARC materials, but in fairly high quantities. On paper, this is the easiest stage, but if you did not save the right parts in advance, it can take several raids.

Material

Amount

ARC Alloy

50

ARC Flex Rubber

The source notes that the first stage feels more like a third stage because the material amount can be annoying, especially if you try to get everything from minor ARCs.

orange_circle emoji Where to Farm Stage 1 Materials

ARC Alloy x50

ARC Alloy can be obtained from almost any ARC part, especially if you recycle ARC materials you do not need. If you rely only on direct loot, the process will take longer because each ARC usually drops only 1–2 pieces.

Efficiency

Recycling ARC parts

Very high

Any ARC

Best advice: recycle unnecessary ARC materials to complete the ARC Alloy requirement faster.

ARC Flex Rubber x10

ARC Flex Rubber usually drops from boss ARCs, but it can also come from Sentinels, Ticks, and Baron Husks.

Source

Comment

Boss ARC

Good source if you can kill them

Sentinels

Rare and hard to farm consistently

Ticks

Good option in Buried City

Baron Husks

Low quantity, usually around 1 piece

Close Scrutiny

Can help passively

If you do not have strong weapons for boss ARCs, the source recommends going in with a free kit and destroying as many Ticks as possible in Buried City.

ARC Performance Steel x10

ARC Performance Steel drops from boss ARCs and also from Hornet and Surveyor. Based on the source, Surveyors are much more reliable because they can drop 2–3 pieces.

Source

Efficiency

Surveyor

Good, 2–3 materials

Hornet

Unstable

Bastions

Good, but dangerous

Bombardiers

Good, but dangerous

Leapers

Farmable if you are confident

Vaporizers

Strong source in Close Scrutiny

Best route: 3–5 raids in Buried City or Blue Gate while focusing on Surveyors.

Advanced ARC Powercell x15

Advanced ARC Powercell is relatively easy to farm. The source recommends waiting for EM Storm or Husk Graveyard and looking for Rocketeer Husks, which often appear during these map conditions.

Source

Why It Is Good

Rocketeer Husks

Common during EM Storm / Husk Graveyard

ARC parts

Can be finished through regular farming

Close Scrutiny

Can be farmed passively

Best method: 1–2 raids during EM Storm or Husk Graveyard.

large_blue_circle emoji Stage 2 — New Rare Materials

The second stage introduces materials that are more heavily tied to Close Scrutiny. The first two items can be farmed from easier ARCs, but Vaporizer Regulator and Assessor Matrix require fighting dangerous targets.

Material

Amount

ARC Coolant

15

ARC Thermo Lining

15

Vaporizer Regulator

4

Assessor Matrix

6

The source says that ARC Coolant and ARC Thermo Lining can be farmed quickly from minor ARCs, but Vaporizer Regulator and Assessor Matrix are accessed through the new map condition and its specific enemies.

purple_circle emoji Where to Farm Stage 2 Materials

ARC Coolant x15 and ARC Thermo Lining x15

Both materials can be looted from Assessor, but it is faster to farm them from weaker enemies.

Material

Best Sources

ARC Coolant

Fireballs, Pops, Assessor

ARC Thermo Lining

Fireballs, Pops, Assessor

The source recommends going to Buried City, entering buildings, and farming Fireballs and Pops. They are easy to kill and reliably drop the needed materials. Usually, 2–3 lucky raids are enough.

Vaporizer Regulator x4

Vaporizer Regulator drops from Vaporizer. This is one of the most dangerous major ARCs because it is designed to counter common Raider tactics. On average, one Vaporizer can provide around 2 Regulators if you loot all its parts carefully.

Source

Amount

Vaporizer

Around 2 Vaporizer Regulators

Close Scrutiny

Main search zone

Tip: loot every part that falls off during the fight. Do not check only the main body.

Assessor Matrix x6

Assessor Matrix is obtained from Assessor, but the issue is that an Assessor is usually guarded by at least one Vaporizer. One Assessor can provide around 2–3 Assessor Matrices.

Source

Amount

Assessor

Usually 2–3 Assessor Matrices

Close Scrutiny

Main farming zone

Raid leader tip: do not assume one player can simply distract the Vaporizer while everyone else peacefully loots the Assessor. The source specifically notes that Vaporizer has multi-target attacks and can punish this plan quickly.

red_circle emoji Stage 3 — Final High Gain Antenna Stage

The third stage is the hardest and most demanding one. It requires many rare materials, including even more Vaporizer Regulators and Assessor Matrices.

Material

Amount

Surveyor Vault

10

ARC Synthetic Resin

20

Vaporizer Regulator

15

Assessor Matrix

18

This is where most players will get stuck, because the total amount of Vaporizer Regulator and Assessor Matrix becomes very high.

orange_circle emoji Where to Farm Stage 3 Materials

Surveyor Vault x10

Surveyor Vault can be obtained in several ways. The most direct method is killing Surveyors, but there are alternatives.

Source

Comment

Surveyors

1 Vault per Surveyor kill

ARC Couriers

Can be looted as an alternative

Assessor

Can also drop Surveyor Vaults

If you are already farming Assessors for Matrix, part of the Surveyor Vault requirement may complete naturally.

ARC Synthetic Resin x20

ARC Synthetic Resin can be obtained from Wasps, but the source notes that there is a faster method — Shredders. After the changes, they spawn on more maps, and on open maps they are less dangerous than they were on Stella Montis.

Source

Efficiency

Wasps

Works, but slower

Shredders

Faster, but more dangerous

Open maps

Better for Shredder farming

Stella Montis

More dangerous; avoid if unsure

Vaporizer Regulator x15

The farming method is the same as in Stage 2: kill Vaporizers during Close Scrutiny and carefully loot every part.

Source

Comment

Vaporizer

Main source

Close Scrutiny

Best map condition

One Vaporizer

Around 2 Regulators

For the full project, you need 19 Vaporizer Regulators total, so expect several Vaporizer kills or very lucky raids.

Assessor Matrix x18

Assessor Matrix again comes from Assessor, but in Stage 3 you need much more of it. One Assessor may drop 2–3 Matrices, so you will need several successful raids.

7

Turn in materials by stage and claim rewards

Raid leader tip: do not enter Close Scrutiny for every material. First, complete everything that can be farmed more safely, then take risks for Vaporizer Regulator and Assessor Matrix.

large_blue_circle emoji Why Vaporizer Is the Main Problem

Vaporizer is one of the hardest major ARCs in the current farm. It is dangerous because it breaks common Raider tactics, attacks multiple targets, and often protects objectives or enemies needed for the project. For High Gain Antenna, it matters especially because it drops Vaporizer Regulator.

Why Vaporizer Is Dangerous

What It Means

Multi-target attacks

You cannot distract it with only one player safely

High damage

Mistakes quickly lead to death

Tied to Close Scrutiny

Other Raiders are often nearby

Required for Regulators

You cannot ignore it

Loot drops from parts

You must loot carefully after the fight

How to Improve Vaporizer Farming Success

Tip

Why It Helps

Bring a proper PvP / PvE loadout

Free kits can be too weak for serious fights

Loot every detached part

Regulator may not be only in the main body

Avoid unnecessary fights near other Raiders

Losing the loot wastes the whole run

Use range and cover

Vaporizer punishes open positions

Do not try to face-tank it

Play around control and damage

Extract quickly after looting

Close Scrutiny attracts other players

purple_circle emoji Assessor Matrix — How to Avoid Wasting Time

Assessor Matrix looks easier because you only need to loot an Assessor, but in practice the Assessor is often protected by a Vaporizer. Because of that, Matrix farming becomes a full combat scenario.

Problem

Solution

Assessor is guarded by Vaporizer

Decide first whether to kill or bypass the Vaporizer

Vaporizer attacks multiple targets

Do not rely on one bait player

Many Matrices are required

Plan several raids

Other players may be nearby

Loot fast and leave

You can die after looting

Extraction matters more than one extra kill

red_circle emoji High Gain Antenna Rewards

orange_circle emoji Which Rewards Matter Most for Combat?

Torrente II

Torrente II is a high fire-rate LMG. The source calls it one of the best options for Stella Montis. It works well for aggressive play, suppression, and fighting dangerous targets.

Bobcat III

Bobcat III is a fast and accurate SMG that melts enemies, but demands precision. The source notes that missing shots with Bobcat is very punishing because it burns through the magazine in less than 0.5 seconds.

Vita Spray

Vita Spray is one of the best healing items because it heals fast and can help not only you, but also nearby teammates.

Photoelectric Cloak

Photoelectric Cloak is especially important for the new map condition because it cloaks you from ARCs and makes you invisible to them.

Snap Hook

Snap Hook is a strong traversal utility, but it is highly desired, so use it carefully near hostile Raiders.

yellow_circle emoji Is There a Time Limit for High Gain Antenna?

No, the project has no strict time limit. The source FAQ states that High Gain Antenna can be completed at your own pace because the time limit on player projects was removed in the Shrouded Sky season.

Question

Answer

Is there a deadline?

No

Can you finish it later?

Yes

Do you need to rush?

Only if you want the rewards faster

Can you farm gradually?

Yes

Raid leader tip: if Close Scrutiny feels too risky or crowded right now, do not throw away your loot for one attempt. The project can be completed gradually.

large_blue_circle emoji Practical Instructions

For Beginners

Do not start with Close Scrutiny if you have no basic materials yet. First collect ARC Alloy, ARC Flex Rubber, ARC Performance Steel, and Advanced ARC Powercell through safer routes.

Recycle unnecessary ARC parts for ARC Alloy. This is faster than waiting for the full amount to drop directly.

For ARC Flex Rubber, farm Ticks in Buried City if you do not have good weapons against boss ARCs.

For ARC Performance Steel, look for Surveyors. They usually give more value than Hornets.

For Stage 2

First complete ARC Coolant and ARC Thermo Lining. They drop well from Fireballs and Pops inside Buried City buildings.

Do not chase Vaporizer Regulator without preparation. Vaporizer is dangerous, and losing the raid can cost more than the progress itself.

After killing a Vaporizer, always loot all parts. A Regulator may be found in detached parts from the fight.

Assessor Matrix is better farmed with a team because Assessor is often near a Vaporizer.

For Stage 3

Treat Stage 3 as a separate major farm. It needs many Regulators and Matrices, so do not expect to finish everything in one calm raid.

Surveyor Vaults can be collected from Surveyors, ARC Couriers, and Assessors. If you are already farming Assessor Matrix, check for extra Vault drops too.

ARC Synthetic Resin is faster through Shredders, but remember the risk. Wasps are safer but slower.

Do not get greedy. If you already found several rare materials, extracting is often better than dying while trying to grab one more piece of loot.

For Close Scrutiny

Close Scrutiny is the main source of difficult materials, but it is also where other players go. Treat every raid as PvP-dangerous.

Bring gear that can fight both ARCs and Raiders. A pure PvE loadout may not save you from another player.

Do not stay in one place too long after killing a Vaporizer or Assessor. The fight sounds and loot can attract others.

If you play in a team, assign roles in advance: who watches for players, who loots, who finishes ARCs, and who covers extraction.

For Safe Farming

Use free kits only for simple materials or scouting. For Vaporizer and Assessor, bring a proper loadout if you want a real chance to extract.

Do not try to complete every material in one session. High Gain Antenna has no deadline, so stable progress is better than a risky all-in.

Complete cheap and simple materials first, then move to rare ones. This way, you do not carry unnecessary valuable loot into dangerous zones.

After getting Vaporizer Regulator or Assessor Matrix, start thinking about extraction immediately.

Beginner Mistakes

The first mistake is underestimating the project because it has only three stages. The material list is heavier than it looks.

The second mistake is trying to farm Vaporizer Regulator without understanding Vaporizer. This enemy can quickly destroy an unprepared player.

The third mistake is not looting all Vaporizer parts after the fight. You can miss the Regulator this way.

The fourth mistake is entering Close Scrutiny with a weak loadout and relying only on luck.

The fifth mistake is ignoring alternative material sources. Surveyors, Ticks, Fireballs, Pops, Shredders, and Rocketeer Husks can speed up the project a lot.

The sixth mistake is getting greedy after a rare drop. Sometimes the best play is to extract immediately.

Final Thoughts

High Gain Antenna in ARC Raiders is a short but demanding player project. It has only 3 stages, but completing it requires many ARC materials, including rare Vaporizer Regulator and Assessor Matrix, both tied to the dangerous Close Scrutiny map condition.

The first stage requires basic materials: ARC Alloy, ARC Flex Rubber, ARC Performance Steel, and Advanced ARC Powercell. The second stage adds ARC Coolant, ARC Thermo Lining, Vaporizer Regulator, and Assessor Matrix. The third stage becomes the main challenge: Surveyor Vaults, ARC Synthetic Resin, more Regulators, and more Matrices.

The best way to finish the project faster is not to farm everything randomly, but to use the correct sources: recycling ARC parts for ARC Alloy, Ticks for Flex Rubber, Surveyors for Performance Steel and Surveyor Vaults, Rocketeer Husks for Advanced ARC Powercells, Fireballs and Pops for Coolant / Thermo Lining, Shredders for Synthetic Resin, Vaporizers for Regulators, and Assessors for Matrices.

The rewards are genuinely worth attention: Torrente II, Bobcat III, strong attachments, Vita Spray, Photoelectric Cloak, Snap Hook, and 500 Raider Coins. The main rule is simple: do not try to complete everything in one risky push. The project has no deadline, so it is better to progress steadily, extract rare materials safely, and avoid greed after a good drop.
