Arc Raiders High Gain Antenna Overview

The High Gain Antenna is a new player project in Arc Raiders that is linked closely to the storyline for the Flashpoint Update. Celeste’s radar is being swamped by unknown aircraft signatures, and the High Gain Antenna is the device Celeste and Shani will use to locate the unknown craft. The storyline links very directly to the ARC Operation Close Scrutiny and the Assessor landings in the Rust Belt area.

Like other projects, such as Trophy Display and Weather Monitor Systems, this is structured in a similar way, where you donate particular resources during each step and get rewarded with equipment. The difference between this and other projects, however, is the fact that there are three stages as opposed to five, two of which will have exclusive Flashpoint content accessible via Close Scrutiny.

Key differences from previous Arc Raiders projects:

• Only three stages instead of five.
• No grand completion bonus — all rewards are distributed per stage.
• Stages 2 and 3 are entirely dependent on the Close Scrutiny map condition.
• Introduces two new exclusive materials: Vaporizer Regulator and Assessor Matrix.
• Total payout of 500 Raider Tokens makes it the most token-valuable project to date.

To access the High Gain Antenna project, open the Raiders tab in Speranza, navigate to Projects, and select the High Gain Antenna. Materials must be submitted manually after collecting them during raids.

If you don’t have time to complete High Gain Antenna project manually, our professional players can do it for you instead.

Arc Raiders High Gain Antenna All Stages

The High Gain Antenna project consists of three construction stages. Each stage has four required materials and a fixed reward set. You cannot skip stages and must complete them in order. Materials for future stages can be gathered and stored in your stash before unlocking those stages, which is strongly recommended for Stages 2 and 3 given the Close Scrutiny dependency.

Want to get your hands on all these Arc Raiders Materials to skip the grind? We can help you with just that!

Arc Raiders High Gain Antenna Stage 1 — Sturdy Base

High Gain Antenna for Arc Raiders Stage I is by far the easiest among the three Stages and does not involve Close Scrutiny either. It uses materials that can be gathered during regular missions where enemies drop standard ARC resources. The problem with this stage isn’t scarcity; rather, it is the sheer number of materials needed – Arc Alloy 50, which is quite a stack.

Stage 1 Required Materials:

Stage 1 Rewards: Torrente II, Extended Medium Mag III, Extended Barrel, Padded Stock.

Bastion and Surveyor are the two best options to consider while targeting Stage 1, since they will allow you to get all the three rare materials. Non-crashed ARC Probes and Couriers may drop Arc Flex Rubber and Arc Performance Steel as well, which makes the latter a passive part of Stage 1.

Fighting those Arcs might prove difficult without the right equipment, so make sure you have a good Arc Raiders Build before you start.

Arc Raiders High Gain Antenna Stage 2 — Data Logger

This is where the Arc Raiders High Gain Antenna project really gets into gear. While the first two items can still be collected through regular raids, the last two items are only available on the Close Scrutiny condition map. This stage is where the Arc Raiders High Gain Antenna project really hits its first wall.

Stage 2 Required Materials:

Stage 2 Rewards: Bobcat III, Extended Light Mag III, Vertical Grip III, 100 Raider Tokens.

Arc Coolant and Arc Thermo Lining are common enough to farm across regular raids, but targeting them during Close Scrutiny is more efficient since the condition boosts overall ARC loot drops.

A single Vaporizer can drop multiple Regulators, so the actual number of kills needed may be lower than four.

Arc Raiders High Gain Antenna Stage 3 — Parabolic Dish

The final stage of Arc Raiders High Gain Antenna significantly increases the demands on Close Scrutiny-exclusive materials. Combined with Stage 2, you need a total of 19 Vaporizer Regulators and 24 Assessor Matrixes across the whole project. This stage also introduces the Surveyor Vault, which requires hunting Surveyors, and Arc Synthetic Resin, which has a broader drop pool and can be farmed more passively.

Stage 3 Required Materials:

Stage 3 Rewards: Vita Spray, Photoelectric Cloak, Snap Hook, 400 Raider Tokens.

Arc Synthetic Resin is the most accessible Stage 3 material, given how many enemy types drop it. Shredders now spawn on all maps since the Flashpoint Update, making Resin easier to gather than in previous patches.

Surveyors appear more frequently during Close Scrutiny, so running the condition simultaneously handles Surveyor Vaults, Vaporizer Regulators, and Assessor Matrixes in one session. Buried City is recommended for Stage 3 Close Scrutiny runs due to its dense building cover, which makes fighting Vaporizers significantly more manageable.

There are many PvP fights during Close Scrutiny, as many players want to obtain the same loot. Get our PvP Loadout Bundle to gain an advantage and speed up the project completion.

Arc Raiders High Gain Antenna Rewards

All rewards from Arc Raiders High Gain Antenna are distributed on a per-stage basis. There is no bonus for completing the full project. The total reward pool across all three stages includes two weapon blueprints, multiple high-tier attachments, three utility items, and 500 Raider Tokens.

Sturdy Base Rewards — Stage 1:

• Torrente II;
• Extended Medium Mag III;
• Extended Barrel;
• Padded Stock.

Data Logger Rewards — Stage 2 :

• Bobcat III;
• Extended Light Mag III;
• Vertical Grip III;
• 100 Raider Tokens.

Parabolic Dish Rewards — Stage 3:

• Vita Spray;
• Photoelectric Cloak;
• Snap Hook;
• 400 Raider Tokens.

The rewards from the final stage are the most valuable of the three. The Photoelectric Cloak and Snap Hook are strong utility items useful in any loadout, and 400 Raider Tokens in a single payout is the largest token reward currently available from a single project stage in the game. The 500 total Raider Tokens across all stages make the High Gain Antenna the most token-efficient project added to Arc Raiders so far.

How to Farm High Gain Antenna Materials

Farming materials for the High Gain Antenna in Arc Raiders is important to finish the project. Some materials come from regular ARC enemies, while others only appear in the Close Scrutiny map condition. Focusing on the right enemies and collecting materials ahead of time makes completing each stage easier.

How to Get Vaporizer Regulators

Vaporizer Regulators only drop from Vaporizers in Arc Raiders. They won’t spawn in standard raids — they’re exclusive to the Close Scrutiny map condition. Check the world map for the Close Scrutiny icon and queue into one of the four available exterior maps.

Vaporizers are the primary protectors of the Assessor probes. You will usually find two or more circling every Assessor landing site. A single Vaporizer can drop multiple Regulators, so looting every separated part after the kill is critical — parts that detach during the fight are each individually lootable.

Tips for farming Vaporizer Regulators efficiently:

• Target the eight thrusters — two at each of the four corners — to ground the Vaporizer and make it stationary
• Never fight a Vaporizer in the open; use buildings and solid walls to avoid their tracking laser
• Wait for their front-facing energy shield to drop before throwing gadgets or Wolfpacks
• Use the Hullcracker or Equalizer for their heavy armor
• Deploy a Surge Coil on the ground to manage Shredders while focusing on the aerial threat
• Non-crashed ARC Probes have a chance to give you Vaporizer Regulators, though it is a rare occurrence — prioritize direct Vaporizer kills as the primary source

How to Get Assessor Matrixes

Each Assessor in Arc Raiders has three lootable containers on its legs. A single breach can yield more than one Matrix, so efficient looting matters more than raw encounter count.

Arc Raiders Assessor Matrix farming tips:

• Clear Vaporizer needs to converge on the Assessor before breaking — the alert will call for reinforcements instantly.
• Take an extra group; there is too much ARC density at the Assessor for a lone player.
• Photoelectric Cloak is good to use for the break-in if the place cannot be cleared out.
• Dolabra Shotgun Blueprint is found off Assessors as well, although only one blueprint can drop off each Assessor, so prefer Matrixes if you do not need the Blueprint.
• Prepare your Assessor Matrixes beforehand for Stage 3, even if you’re still completing Stage 2.

General Farming Tips

Here we have also prepared some general High Antenna resource farming tips that can help you to be more efficient:

• Taking advantage of the Close Scrutiny map condition is recommended, as it increases Arc material loot and spawns plenty of high-tier machines including Surveyors and Vaporizers.
• Pre-farm Stage 2 and Stage 3 materials during Close Scrutiny runs even before completing Stage 1 — all materials store in your stash.
• Buried City is the best map for Stage 3 runs due to building density providing reliable cover against Vaporizer lasers.
• Surveyors during Close Scrutiny contribute both Surveyor Vaults for Stage 3 and Arc Performance Steel for Stage 1 simultaneously.
• Arc Synthetic Resin can be gathered passively across all map types since Sentinels, Shredders, and Wasps appear everywhere.
