🔧 Component Overview

The DJI Agras T50 OEM External RC PLUS Remote Antenna, DJI material number YC.DZ.AA000253, is the external antenna for the RC Plus remote controller, carrying the command-and-control radio link between the operator and the aircraft.

An antenna is not a wire that carries signal, it is a shaped piece of hardware whose geometry decides where the energy goes. That matters on an ag aircraft because the operator stands still and the machine works away from him in every direction. Damage that changes the shape, or moisture that changes what is inside the radome, does not produce a clean failure. It produces a link that still connects, still shows bars on the ground, and gives up at the far end of a pass.

The RC Plus carries more than one external antenna, and that redundancy is exactly what hides a fault. Lose one and the link leans harder on the remaining ones. Close to the operator nothing looks different at all. The loss only becomes visible where the margin was already thin, which on a working aircraft means the outside corners of the field, behind a treeline, or at the end of a long pass with the aircraft low.

These parts live a hard life outside the flight envelope. They are folded and unfolded every day, leaned against truck beds, closed in doors, rained on, and left in the sun on a dash. The plastic goes chalky under UV, the joint at the base works loose, and the flexible section inside the base takes a fatigue cycle every time the antenna is swung. Most failed antennas were killed on the ground, not in the air.

⚙️ Functional Purpose

The antenna transmits and receives the control link. A damaged, cracked, or degraded antenna shortens range, weakens signal, and raises the risk of control dropouts at distance.

This antenna carries the command and control link, which is the one radio path on the aircraft that has no fallback the operator can use. Video can degrade and a job continues. Telemetry can stutter and a job continues. When command and control margin runs out the aircraft executes its own lost link behavior, and where it does that is decided by where it was when the link went, not by what the operator wanted at that moment.

Orientation is part of the job, not an accessory to it. An antenna radiates strongly out of its broad face and very weakly off its tip, so the useful field is a doughnut around the element rather than a beam out the end. Pointing the tips at the aircraft aims the weakest part of the pattern at exactly the thing you are trying to reach, and it is the single most common self inflicted range problem in the field.

Antenna condition also sets how much interference the system can tolerate. Link margin is the gap between the signal you receive and the noise floor around you. Center pivots, grain dryers, power lines, and other operators on the same band all raise that floor. A healthy antenna gives enough margin to work through it. A degraded one spends its margin on its own losses and leaves nothing for the environment to eat.

⚠️ Common Replacement Indicators

• Reduced transmission range
• Weak or dropping signal at distance
• Cracked, bent, or damaged antenna
• Connector damage at the antenna base
• Intermittent link warnings

Confirm before you order: this part is DJI number YC.DZ.AA000253, listed for DJI Agras T50 RC Plus remote controller. Match it to your parts diagram or the label on your existing part before ordering.

Range that has quietly shortened compared with the same field last season, with no change to the aircraft, the software, or where you stand. Gradual loss is the classic signature of a physical antenna problem: moisture in the base, a fatigued flexible section, or a connector that has corroded. A sudden failure gets noticed; a slow one gets blamed on the field.

Dropouts that happen only when the aircraft is on one particular side of you. That is a lopsided radiation pattern, which is what you get when one element is dead or detuned while the others still work. Note the compass direction and the controller orientation when the warnings appear, and see whether the bad sector follows the controller when you turn around with it.

A link that is solid near the truck and falls apart at distance. That is a loss of gain rather than an outright open circuit, and it points at physical damage to the element or water sitting inside the radome. Nothing about the close in behavior of the link will reveal this, which is why an antenna can pass a preflight check and still fail the job.

Link quality that twitches when you flex the antenna at its base with the aircraft powered and sitting on the ground. That is a broken conductor or a loose center contact making and breaking. It is the most direct evidence you can get without instruments, and an antenna that does this is finished regardless of how good it looks.

Chalky, whitened, or crazed plastic on the radome, a soft or spongy spot, or a hinge that flops instead of holding its detent. UV and chemical exposure embrittle the housing, and once it cracks, moisture reaches the element. A hinge that will not hold position also means the operator cannot repeat an orientation, so the link changes every time the controller is picked up.

Visible damage at the base: a bent or crushed neck, a cross threaded or chewed fitting, green or white deposit on the contact. Anything wrong at the base affects every watt going in or out. It also risks damaging the port on the controller, which turns a cheap part into an expensive one.

📐 Specifications

DJI Material Number: YC.DZ.AA000253

Part: External RC PLUS Remote Antenna

Fits: DJI Agras T50 RC Plus remote controller (supplier-listed fitment)

Assembly: Remote Controller (RC Plus)

Quantity: 1

Condition: Brand new

Assembly position: External antenna on the RC Plus remote controller, one of the set the controller uses for the command and control link

Published RF figures: DJI does not publish gain, pattern, VSWR, or band edges for this antenna in the public parts list. Do not substitute figures quoted for other antennas. Match the DJI material number instead.

Sold as: Single antenna. The antenna port, its internal pigtail, and the controller housing are not part of this listing and are serviced separately.

Regulatory note: The controller is certified as a system together with its supplied antennas. Fitting a third party or higher gain antenna changes the radiated characteristics of that certified system and is the operator's own compliance problem, not an upgrade.

🧰 Fitment Verification Before You Order

This listing is DJI material number YC.DZ.AA000253. That number, not the description, is what makes a part match. Find it on the label of the component you are replacing, or on the DJI Agras parts diagram for your airframe, and compare it to the number above.

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. 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 External RC PLUS Remote 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.

🚜 Necessary For

• Restoring full control range and signal strength
• Replacing a cracked or damaged antenna
• Curing signal-dropout warnings
• RC Plus controller service

Restoring full control link margin after an antenna has been crushed, cracked, closed in a door, or snapped at the base

Clearing a lopsided link that drops out only when the aircraft is on one side of the operator, once the fault has been traced to a single element

Refreshing weathered antennas on a controller that has spent seasons outdoors, where the housings have gone chalky and the hinges no longer hold position

Returning a controller to the certified antenna configuration after somebody fitted a third party antenna to it

💵 What Downtime Actually Costs

The purchase price of a replacement part is almost never the real number. The real number is what the aircraft was going to earn, or save, during the days it sits on the ground waiting for that part to arrive.

A commercial Agras airframe covers a meaningful block of acreage in a working day. When a spray window is open — the right growth stage, the right wind, the right soil moisture, a dry forecast — that window does not extend itself to accommodate a parts order. It closes. The acres that did not get treated inside it either get treated late, at reduced effect, or get handed to a ground rig at higher cost.

Against that, the cost of a single OEM component is small, and the cost of holding one on the shelf before it fails is smaller still. Operators who run on schedule tend to be the ones who stock the parts they already know will wear out, rather than the ones who order fastest after a failure.

For the External RC PLUS Remote Antenna, that logic is straightforward: it is an inexpensive component relative to the DJI Agras T50 it serves, it is a known service item rather than a surprise, and having one in the truck or the shop converts a multi-day grounding into an afternoon of work.

This is also why we ship from U.S. stock rather than drop-shipping from overseas. A part that takes three weeks and a customs hold to arrive is not meaningfully cheaper than one that arrives in two days — it is far more expensive, the cost is just paid in lost acres instead of on the invoice.

💡 Why This Part Matters

Range and a rock-solid link are safety. A damaged antenna quietly shrinks both until a dropout finds you at the far end of a pass. A cheap part that protects the whole flight.

The reason this small part gets treated seriously is the asymmetry of the outcome. A degraded antenna costs nothing until the moment margin runs out, and at that moment the aircraft is usually at maximum distance, low, over somebody's crop, with a partial tank. What follows is decided by the lost link setting rather than by the operator. That is a large downside attached to a part that costs less than an hour of application work.

Antennas also fail in a way that defeats normal troubleshooting. Operators chase link problems into firmware, interference, terrain, and even the aircraft radio, because a damaged antenna still connects, still pairs, and still shows a strong indication with the aircraft twenty feet away. Ruling the antenna in or out first, with a swap, is faster and cheaper than any of the other paths and it eliminates the most likely cause.

There is a practical argument for keeping spares rather than one spare. The antennas on a controller have all seen the same sun, the same chemical, and the same number of fold cycles. When one goes from age rather than from an impact, the others are the same age. Operators who carry a set find they change them together and stop thinking about link problems for the rest of 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.

Genuine OEM only. Every part we list as OEM is a genuine DJI component in new condition. We do not substitute aftermarket parts, and we do not relabel. If a listing says OEM, that is what ships.

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.

Is this a genuine DJI OEM part? Yes. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller and stocks genuine DJI Agras OEM replacement parts. This component is supplied brand new.

How do I work out which antenna is the bad one?

Swap it and see whether the fault moves. Note which port the suspect antenna is on, move it to a different port, and move a known good one into the port it came from. Repeat your range or link check. If the problem follows the antenna to its new position, the antenna is bad. If the problem stays with the original port, the fault is in the port, its internal pigtail, or the radio behind it, and a new antenna will not fix it.

Is it safe to fly with a port empty or an antenna removed?

No. A transmitter expects a matched load on every port. With a port empty, energy that should have radiated is reflected back into the output stage instead, which stresses the radio and can damage it permanently. It also leaves the remaining antennas covering the whole job on their own, with no diversity and less margin. Do not power up to transmit until every port has an antenna on it.

Which way should the antennas point during a job?

Present the broad flat faces of the antennas toward the working area and keep the tips pointed away from it, usually upward and outward rather than laid over toward the aircraft. The weakest part of an antenna pattern is straight off the tip, so aiming the tips at the machine puts it in the null. Set them once, stand so the controller stays roughly square to the field, and do not swing the controller around to follow the aircraft.

Dropouts only happen when the aircraft is behind me or off to one side. What does that point at?

A pattern with a hole in it, which usually means one element is dead or detuned while the rest still work. Test it deliberately: park the aircraft at a fixed distance, hold the controller level, and turn slowly through a full circle while watching the link readout. A healthy set gives a shallow, gradual variation. A single deep drop that repeats at the same relative bearing is a failed element, not terrain.

How do I check the port on the controller rather than the antenna?

Look into the port under good light with the controller powered off. The center contact should be straight, bright, and centered, the threads or retaining feature clean and undamaged, and the surround free of green or white deposit. Then fit a known good antenna and flex it gently at the base while the link is up. Movement in the readout with a known good antenna fitted puts the fault in the port or the pigtail behind it.

Can I fit a higher gain aftermarket antenna to get more range?

It is a bad trade for an ag operator. The controller is type accepted as a system with its supplied antennas, so changing them makes the radiated result your responsibility rather than the manufacturer's. High gain antennas also buy their reach by flattening the pattern, which strips coverage from directly overhead and from close in low angles, exactly where a spray aircraft spends its turns. Fix the real problem and stay with the OEM part.

The link is fine at the truck and poor at the far end. Is that the antenna or the aircraft?

Either can do it, so separate them. Repeat the same pass from a different standing position, higher and clear of obstructions, and see whether the distance at which it degrades changes. Then swap the suspect antenna to another port and repeat again. Terrain and standing position will move the failure distance around; a bad antenna will keep failing at roughly the same distance and will carry the problem with it when you swap ports.

What is the correct way to fit and remove one?

Power the controller down first. Support the base of the antenna and turn or release only at the fitting, never by twisting the body or pulling on the tip. Start any threaded fitting square and by hand, and stop at hand tight. These fittings are not torqued with a tool, and a wrench on one will damage the port long before it improves the connection. Confirm the antenna folds through its full travel and holds its detent before you consider it fitted.

What shortens the life of these antennas, and how should spares be kept?

Sun, chemical, and fold cycles, in that order. Store the controller in its case with the antennas folded rather than face up on a truck dash. Rinse and dry the controller exterior after a chemical day instead of letting residue sit on the housings. Keep spares in their packaging and out of direct light, and check a spare for cracks and a straight center contact before you trust it, because an antenna damaged in a toolbox looks new until it is fitted.
