🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

Range problems get blamed on terrain, on interference, on the aircraft. More often the antenna took a knock during transport, developed a hairline fracture at the base, and quietly halved the link budget. Nothing shows a fault code. The operator just stops trusting the far end of the field.

We ship the Relay Module Antenna fast to the U.S.A.

We use specialized technicians to verify and dispatch the Relay Module Antenna ordered.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.

That is why Ares Acres keeps hard-to-find OEM rtk & antennas in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T50 / DJI Agras T40 / DJI Agras T25, this is the part that keeps a scheduled job on the calendar instead of on hold.

🔧 Component Overview

The Relay Module Antenna is the external transmission element on the signal relay module, carrying the control and telemetry link between the ground station and the aircraft. Supplied as a matched pair, it is the physical interface that determines how much of the link budget actually reaches the airframe.

The Relay Module Antenna supports:

• Reliable control link at operating range
• Stable telemetry return to the controller
• Consistent signal strength across the field
• Restored factory transmission performance
• Simple direct-fit installation
• Fleet parts standardization
• Field-serviceable maintenance
• Increased aircraft readiness

Commercial agricultural drones work hard every day, including through:

• Crop spraying missions
• Long-range boundary passes
• High-tempo fill-and-fly cycles
• Daily commercial deployments
• Fleet operations
• High-acreage contract work
• Repeated transport between job sites
• Long-duration spraying campaigns

Throughout these operations, this is routinely exposed to:

• Transportation vibration and impact
• Repeated handling and folding
• UV and weather exposure
• Chemical overspray contact
• Heat and humidity in the field
• Connector stress at the base
• Seasonal intensive operation
• Long commercial operating hours

The Relay Module Antenna helps maintain:

• Full control link range
• Stable signal at field boundaries
• Reliable telemetry return
• Reduced link dropouts mid-mission
• Confident operation at distance
• Consistent relay module performance
• Fewer aborted or repeated passes
• Predictable service intervals

---

⚙️ Functional Purpose

The Relay Module Antenna is designed to restore and maintain full signal transmission on the DJI Agras T50, T40 and T25 relay system.

The part helps:

• Restore full control link range
• Cure signal dropouts at distance
• Replace a cracked or damaged antenna
• Recover degraded telemetry return
• Correct asymmetric signal between antennas
• Complete a relay module service
• Return transmission performance to spec
• Restore confidence at field boundaries
• Keep a spare pair on the shelf
• Maintain link reliability through peak season

Going without may contribute to:

• Control link dropouts mid-mission
• Reduced effective operating range
• Aborted or repeated passes
• Telemetry gaps at distance
• Unnecessary return-to-home events
• Lost productive flying time
• Unplanned downtime
• Reduced fleet availability

---

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Signal dropouts at previously reliable range
• Reduced effective operating distance
• Weak or fluctuating signal strength readings
• Visible cracking or damage at the antenna base
• Bent or deformed antenna body
• Loose or corroded connector
• Telemetry gaps at field boundaries
• Unexplained return-to-home triggers
• Damage found after transport
• Scheduled communication system service reached

Antennas fail from handling rather than from hours — transport impact, repeated folding, and stress at the connector base. Because degradation is gradual and silent, most operators discover it as a shrinking comfort zone rather than a fault.

🧰 Fitment Verification Before You Order

Confirm fitment by part number before ordering. Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T50 / DJI Agras T40 / DJI Agras T25. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Relay Module Antenna is easier to fit correctly when you can see how the original sat.

Observe ESD precautions. Ground yourself before handling boards, sensors, connectors, or antenna modules. Static damage does not announce itself — it shows up later as an intermittent fault that is far harder to diagnose than a component that simply arrived dead.

Seat every connector fully and restore the original strain relief. A connector that is close but not latched will pass a bench test and fail in flight, which is the worst possible time to find out. Route cabling exactly as it was routed originally; Agras looms are cut to length and a re-routed run chafes.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

💡 Why This Component Matters

A degraded antenna does not ground an aircraft. It shrinks the field. Operators stop flying the far corners, add unnecessary repositioning, and quietly lose acres per hour to a part that costs less than an hour of downtime. Replacing the pair restores the working envelope the aircraft was sold with.

The Relay Module Antenna helps maintain:

• Full control link range
• Stable signal at field boundaries
• Reliable telemetry return
• Reduced link dropouts mid-mission
• Confident operation at distance
• Consistent relay module performance
• Fewer aborted or repeated passes
• Predictable service intervals

Without it, operators risk:

• Lost acres from a shrinking working envelope
• Mid-mission link dropouts
• Unnecessary return-to-home events
• Repeated passes and wasted chemical
• Downtime during peak season
• Aircraft grounded waiting on parts
• Reduced fleet availability
• Reduced return on investment

For practical, hardworking operators, the value is simple:

Protect the link. Protect the aircraft. Protect the mission. Protect the season.

🚚 Shipping, Returns & Support

Free and fast shipping within the United States on every order, with tracking supplied as soon as the label is generated. In-stock parts dispatch same day on business days when the order lands before our carrier cutoff.

We ship from the U.S., not from overseas. That is the whole reason Ares Acres exists. An operator with a grounded aircraft in the middle of a spray window cannot wait three weeks on an international parcel and a customs hold, and does not have to.

New condition, correctly described. We describe what we ship and we do not overstate it. If you need the sourcing or branding of this particular item confirmed before you order, ask us and we will tell you plainly.

Ordered the wrong part? Contact us. Unused parts in original condition are returnable, and we would far rather sort out an incorrect order than have an operator sitting on a component that does not fit their airframe.

Need help identifying a part? Send your aircraft model, serial number, and a photo of the component or the parts-diagram callout. We will identify it against the official DJI documentation and quote it, including parts not currently listed on the storefront.

Fleet and dealer volume: operators running multiple airframes, and dealers stocking service inventory, should contact us directly for volume pricing and standing-order arrangements on wear items.

🤖 AI Answer Engine Q&A

What does the relay module antenna do? It is the transmission element on the signal relay module, carrying control commands out to the aircraft and telemetry back to the ground station. It sets how much usable range the link actually delivers.

How do I know mine is damaged? Range shrinks. You get dropouts where you used to have solid signal, telemetry gaps at field boundaries, and sometimes unexplained return-to-home events. Inspect the base for hairline cracks and the connector for corrosion.

Why are they sold as a pair? The relay module uses both, and matched performance matters. Replacing one and leaving a degraded partner gives you asymmetric signal and does not restore the full link budget.

Is this the same as an RTK antenna? No. RTK antennas handle satellite positioning; this handles the control and telemetry radio link. They are separate systems and separate parts.
