Digital FPV System

Best Price

$77.27

The iFlight Crystal HD bundle is a low-profile antenna overhaul designed specifically to replace the stock front plate of the DJI FPV Goggles. By integrating two high-gain directional patches into a sleek carbon-fiber faceplate and pairing them with two "stubby" omnis, this kit delivers a massive boost in signal penetration and range without making your goggles feel front-heavy or bulky.

Product Description

iFlight Crystal DJI HD Patch Carbon Stubby Bundle FPV Accessories Version V2 (Visor/Combo) Style Directional/Omni Upgrade

The iFlight Crystal HD antenna system isn't just a clip-on; it is a full replacement for the DJI goggle front panel. It focuses on a clean, integrated aesthetic while moving away from the "insect" look of the stock four-antenna setup.

Engineered Antenna Array: Unlike standard individual patches, this unit contains a dual-antenna array positioned at a 30-degree offset. This specific angling is what allows it to maintain high gain while offering a much wider horizontal beam than its competitors.
Low Profile Design: Because the patch antennas are built directly into the faceplate, the goggles remain slim. This is a huge benefit for pilots who like to toss their goggles into a backpack without having to remove and re-install antennas every time.
High-Quality Materials: The bundle features high-quality RG178 cables and a durable housing. The "Carbon" edition specifically uses a carbon-fiber print that resists scratches and matches the high-end look of the DJI system.
Versatile Mounting: iFlight designed the array so it can be mounted on either the top or bottom pair of RP-SMA connectors on your goggles, giving you the freedom to choose your antenna layout based on your head-tracking or mounting preferences.

Technical Specifications:

Frequency: 5.8GHz (5600–5900MHz)
Gain (Patch): 9 dBi
Gain (Stubby): 3 dBi
Beam Width (Patch): 105° Horizontal, 75° Vertical
Radiation Efficiency: 93%
Axial Ratio: ≤1.6
Polarization: LHCP (Left Hand Circularly Polarized)
Connector: RP-SMA (Custom for DJI Goggles V1/V2)
Weight: 52.1g (Total array)

The Pilot's Reality Check:

Beam Width Advantage: The 105° horizontal beam is the real star here. While many patch antennas require you to point your head exactly at the drone, the Crystal is very forgiving—you can look around fairly freely without your bit-rate dropping off a cliff.
Installation Nuance: Since this replaces the front plate, you have to be careful when tightening the screws into the goggle body. It fits perfectly, but it's a "permanent" feeling mod compared to just screwing on an antenna.
Stubby vs. Long: The included stubbies are great for portability and looking cool, but they are short. If you have a very large head or thick goggle straps, the strap can sometimes partially block the line-of-sight for the stubbies.

🤔 Frequently Asked Questions

Is it actually better than the stock DJI antennas?
Yes, but mostly in the "beam" in front of you. The stock antennas are omnidirectional, meaning they pick up signal from everywhere but don't reach very far. This iFlight Patch has a high 9dBi gain, which significantly improves your signal penetration through trees and buildings, provided your head is roughly pointed toward the drone.
What is the "Carbon" version? Is it real carbon fiber?
The "Carbon" refers to the visual design of the front plate. It is an injection-molded plastic cover with a high-quality carbon fiber print/sticker. It’s built to be durable and lightweight while giving your goggles a more aggressive, premium look.
Will it fit in my goggle bag without taking the antennas off?
This is the biggest selling point. Unlike the Lumenier or TrueRC patches that stick out, the iFlight Crystal is flat against the goggles. You can throw your goggles into almost any standard carrying case or backpack without ever having to unscrew your antennas, saving you time and wear-and-tear on the RP-SMA connectors.
Where should I mount the Patch vs. the Stubbies?
The DJI Goggles have four ports. For the best performance, you should mount the Patch array on the bottom two ports and the two Carbon Stubbies on the top two ports. This ensures that if the drone flies behind you or above you, the Stubbies can catch the signal while the Patch handles the heavy lifting in front of you.
How wide is the signal "window"?
The beamwidth is roughly 105° horizontally and 75° vertically. This is quite wide for a patch antenna. As long as you aren't flying completely behind yourself or at extreme 90-degree angles to your side, you will maintain a solid high-definition bit rate.
