I remember the first time I handed over scrap and watched a rare grip pop out of the rewards screen; my heart kicked. You can feel that same jitter every raid—you and I, hunting specific parts with the clock quietly ticking. If you’ve ever stood over a pile of ARC wreckage wondering which runs matter, this guide will make the choices obvious.
I’ve run dozens of raids, tracked spawn conditions on Discord threads and tested drops in solo runs. You’ll get the checklist, the fastest farming tips, and the reasoning you can use on your next run.
On almost every sortie you’ll spot ARC bits scattered across the map. How to complete the High-Gain Antenna project in ARC Raiders
This project breaks the usual pattern: where past projects ran five levels, the High-Gain Antenna has three stages, each with four donation tasks. You hand over materials found in raids; those items vanish from your pack but buy you weapon parts, attachments and Raider Tokens in return. Treat it like a scavenger hunt in a scrapyard—focused, repetitive, and oddly satisfying.
How do I complete the High-Gain Antenna project?
You progress by donating the exact materials listed in each stage. Each stage accepts only the specified items and gives instant rewards when every task in that stage is fulfilled. Pay attention to map conditions: Close Scrutiny increases Assessor spawns, and Matriarch runs are the easiest ticket to Advanced ARC Powercells.
What rewards are worth farming for first?
Short answer: attachments and tokens. If you need a functional boost, the Extended Medium Mag III, Extended Barrel and Vertical Grip III are useful across builds. If you’re collecting Raider Tokens to buy cosmetics or parts from the vendor, aim for Stage 3—the token payout there is largest and stacks up like a snowball across multiple completions.
Stage 1: Sturdy Base
| Requirements | How to get | Rewards |
|---|---|---|
| 50 ARC Alloy | Drop from almost every ARC when you salvage their remains; also found in random loot. | One Torrente II |
| 10 ARC Flex Rubber | Rare salvage from ARC remains; you’ll see these less often. | One Extended Medium Mag III |
| 10 ARC Performance Steel | Mostly from rarer ARC enemies like Hornets and Fireflies; expect to farm a few runs. | One Extended Barrel |
| 15 Advanced ARC Powercell | Drop from higher-tier ARCs; Matriarch raids guarantee these and speed the process. | One Padded Stock |
Stage 2: Data Logger
| Requirements | How to get | Rewards |
|---|---|---|
| 15 ARC Coolant | Loot mid-tier ARCs—Comets, Pops, Sentinels are the usual suspects. | One Bobcat III |
| 15 ARC Thermo Lining | Found on a variety of ARCs such as Comets, Fireballs, Pops and Turrets. | One Extended Light Mag III |
| 4 Vaporizor Regulator | Loot Vaporizor remains after kills. | One Vertical Grip III |
| 6 Assessor Matrix | Loot ARC Assessors during the Close Scrutiny map condition. | 100 Raider Tokens |
Stage 3: Parabolic Dish
| Requirements | How to get | Rewards |
|---|---|---|
| 15 Surveyor Vault | Destroy and loot Surveyors; they spawn on all map types, more often during Close Scrutiny. | One Vita Spray |
| 15 ARC Synthetic Resin | Rare drops from Shredders and Sentinels; also seen on Baron and Deforester Husks. | One Photoelectric Cloak |
| 15 Vaporizor Regulator | Loot from Vaporizor remains. | One Snap Hook |
| 18 Assessor Matrix | Loot ARC Assessors during Close Scrutiny map condition. | 400 Raider Tokens |
When you scan the event tracker you’ll notice no countdown timer. When will the High-Gain Antenna project expire from ARC Raiders
At present there’s no public end date. The safest play is to assume the project will remain until the next major update—historically the studio releases patches on a monthly rhythm. If you want the token haul and attachments, start on the materials you can farm repeatedly (ARC Alloy, Surveyor Vaults, Vaporizor Regulators) and stack runs.
If you’re ready to tackle it now, my quick advice: run a Matriarch mission when you need Advanced ARC Powercells, hunt Close Scrutiny maps for Assessors, and group with a Discord squad if you want faster clears. You’ll finish Stage 1 fastest, Stage 3 gives the biggest token payout.
While you gather parts, you can pick up these extra quests to keep momentum:
- Clamoring for Attention
- Outstanding Balance
- Dust on the Wires
Will you start grinding parts this week or wait until someone on Reddit posts a faster route?
