Product Description

The TrueRC Duality 2.4/5.8 Stubby antennas are specifically engineered to upgrade the DJI FPV Goggles V2 and the Fat Shark HDO3. They are "dual-band" antennas, meaning they cover both the 2.4GHz and 5.8GHz frequencies used by the DJI system, allowing for better range and signal penetration in a much smaller form factor than the stock linear antennas.

True Dual-Band Performance: Most FPV antennas only support 5.8GHz. The Duality is uniquely designed to handle the 2.4GHz control and video link used by the DJI FPV Drone and O3 Air Unit, as well as the standard 5.8GHz band. This ensures you maintain a solid link regardless of which frequency your system switches to.
Low-Profile "Stubby" Design: Standing at only 22mm tall, these antennas are significantly shorter than the stock DJI "ducky" antennas. This reduces the risk of them snagging on branches or breaking during transport. Many pilots leave them on the goggles permanently.
Hand-Tuned Precision: Every single TrueRC antenna is hand-tuned on a professional network analyzer. This ensures that the SWR (Standing Wave Ratio) is as low as possible, maximizing the radiation efficiency and ensuring your video transmitter isn't working harder than it needs to.
Superior Cross-Polar Rejection: With a rejection rating of -15 to -30dB, these antennas are excellent at filtering out reflected signals (multipathing). This leads to a cleaner, more stable video feed, especially when flying in environments with lots of concrete or metal.
Compatibility Note: While these use an RP-SMA connector designed for the DJI Goggles V2, they can also be used on the original DJI V1 Goggles. However, since the V1 only uses 5.8GHz, TrueRC’s "Singularity" antennas are a more cost-effective choice for that specific model.

Technical Specifications:

Gain: 1.7dBic @ 2.4GHz / 2.8dBic @ 5.8GHz
Polarization: LHCP (Left-Hand Circular Polarized)
Bandwidth: 2.39GHz–2.52GHz & 5.6GHz–6.1GHz
Radiation Efficiency: 99%
SWR: ≤ 1.5:1
Dimensions: 23.3mm (Diameter) x 22.0mm (Height)
Weight: 5.25g per antenna
Connector: RP-SMA

The Pilot's Reality Check:

LHCP vs. RHCP: Ensure you match the polarization of your drone's antenna. Most DJI systems (Air Unit, Vista, O3) use LHCP by default. If you use the wrong polarization, you will experience significantly reduced range.
Bag Friendly: The primary reason pilots buy these isn't just the range boost—it's the convenience. Being able to throw your goggles into a backpack without removing the antennas is a huge quality-of-life improvement.

🤔 Frequently Asked Questions

Why do I need "Dual-Band" antennas for DJI V2 goggles?
The DJI FPV Goggles V2 are unique because they communicate on both 2.4GHz and 5.8GHz frequencies. If you use standard 5.8GHz-only antennas, you risk poor range or even damaging the internal circuitry when the goggles try to transmit on the 2.4GHz band. The Duality is engineered to handle both perfectly.
Is there a performance gain over the stock antennas?
While the primary benefit is the stubby form factor, the Duality antennas are hand-tuned on professional analyzers. They offer a more consistent circular polarization (CP) and better cross-polar rejection than the stock linear antennas, which typically results in a cleaner video feed with fewer "pixels" or dropouts when flying around obstacles.
Do they fit the newer DJI Goggles 2 or Goggles 3?
No. These use an RP-SMA connector. The newer DJI Goggles 2 and Goggles 3 use a specialized MCX connector. To use these on the newer goggles, you would need an MCX-to-RP-SMA adapter, though most pilots prefer antennas specifically designed for those smaller connectors to keep the weight down.
Should I choose LHCP or RHCP?
For the DJI digital system, you should almost always choose LHCP (Left Hand Circular Polarization). The stock DJI Air Unit and O3 antennas are LHCP, and your goggles must match the drone's polarization to ensure maximum range.
Can I leave them on the goggles inside my bag?
Yes! That is their "killer feature." Because they are only 22mm tall, they don't stick out far enough to get snagged or snapped off. This saves you from having to screw and unscrew four antennas every time you fly.
