- Achieve unparalleled transmission reliability with enhanced bitrate performance at extended ranges and through challenging environmental conditions.
Adding new features to the app is straightforward.
- Take away the inventory antennas.
- Insert the BDI Patch. With no instruments or screws required for setup, installation is effortlessly rapid and uncomplicated.
What sets this function apart is its ability to facilitate
- Simple storage solutions minimize frequent removal and reduce wear on MCX connectors.
- Customizable antenna tilts for seamless signal acquisition and optimal transmission.
- With the provided hex wrench, effortlessly fine-tune friction adjustments to securely fasten the antennas and maintain their position during usage.
The product webpage is showcased within the antenna product webpage, but I’m unsure whether this includes it as an optional add-on or requires separate individual purchase. The interior of the DJI Goggles 2 features a remarkably delicate design that safeguards the goggles from scratches, accompanied by an extra layer of comfort during transport.
Drawbacks
When flying drones with excessive-gain antennas, such as the BDI Patch, it’s essential to consider the impact of signal energy on your device, particularly when flying at an angle. To optimize performance, carefully orient the antennas directly towards the drone to ensure a robust signal connection. The pilot must remain cognizant of the drone’s location at all times and be prepared to adjust its trajectory as needed, if required?
The BDI Patch G2 antennas feature Left-Hand Circular Polarization. If paired with the inventory module on the drone, you may potentially experience a significant increase in efficiency and accuracy. To maximize efficiency, consider installing a high-gain circularly polarized (LHCP) antenna on your drone for optimal performance.
While the BDI Patch G2 may be an expensive upgrade option for DJI Goggles 2, it is arguably one of the most costly alternatives available to consumers on the market today?
The BDI Patch G2 antenna was recently tested for its performance in various environments. The test results showed that this antenna has a gain of around 8 dBi and an azimuthal coverage of 90 degrees. The elevation angle range is between -30 to +60 degrees, providing effective communication within the desired area.
Its size is compact, making it ideal for use in vehicles or for fixed installations.
While examining sign penetration, I utilized the DJI Goggles 2 in conjunction with the O3 Air Unit to fly behind 170 meters of dense foliage. Here is the rewritten text:
A comparison was conducted between the video bitrate of BDI Patch antennas and DJI inventory antennas to determine which provided a longer range and better penetration. I carefully evaluated their optimal absorption rate while hovering above the situation.
Outcome
As expected, the BDI Patch Antenna displayed superior efficiency across all bitrates, consistently outperforming its peers during rigorous testing. The video’s bitrate has been significantly enhanced for a more seamless viewing experience, boasting superior security features and virtually eliminating stuttering issues. In contrast, the inventory antennas exhibited intermittent spikes in latency, prompting yellow warnings for low bitrate during the same test location. The BDI Patch Antenna delivers enhanced performance, boasting superior penetration and coverage range compared to standard-issue antennas. While flying straight into the entrance myself, the bitrate hovered around consistently with the BDI patch applied on most occasions, accompanied by the inventory antennas.
While increased receive antenna gain is a benefit, it comes at the cost of a narrower beamwidth, resulting in weaker signal receptions when approaching peripheral or rear areas. It’s clear from my own experiments that this phenomenon was indeed observable. As the aircraft ascended above 90 kilometers, the bitrate plummeted in conjunction with the BDI Patch. In contrast, when using the inventory antennas, the bitrate remained steady around that level.
Although I did not have the opportunity to re-test the FlyFish Flip G2 at this particular event. According to specifications, this antenna’s performance parameters lie between those of standard issue models and the high-performance BDI Patch Antenna in terms of both achievement and beamwidth. When prioritizing penetration, the BDI Patch may be a more suitable option, despite the FlyFish being more affordable.
The device has specifications corresponding to the BDI Patch, with a minor yet notable enhancement in performance. Despite its limitations, the X-Air’s lack of foldability renders it less portable, requiring greater precision in flight direction due to its narrower beamwidth. Although the X-Air can be disconnected from power for storage purposes, it’s essential to minimize the removal of antennas to preserve their integrity, as excessive disconnection can compromise the connectors’ performance over time.
Are the Benefits of the BDI Patch Antenna Worth Its High Price Tag?
While suitable for some pilots, DJI’s inventory antennas may suffice for those flying over open spaces. Despite any reservations, individuals seeking substantial enhancements will find the DJI Goggles 2 a notable upgrade. Its versatile foldable design and customizable positioning render it incredibly practical and portable. While the BDI Patch’s value may be a factor for pilots mindful of their budgets, it’s essential to note that its true potential can only be fully realized when paired with a circularly polarized antenna on the drone – unlike the linearly polarized inventory O3 antenna.
