In the fast-paced world of FPV (First Person View) flying, having a reliable signal is crucial. Enter the Caddx Avatar HD Repeater Module, a device designed to extend your flying range and enhance signal reliability. Ian from MadsRC dives deep into this innovative module, unpacking its features, setup, and potential use cases.
What is the Caddx Avatar HD Repeater?
The Caddx Avatar HD Repeater is a relay device that connects your VTX (video transmitter) to your goggles, allowing for improved signal transmission. It can be positioned at a higher elevation or midpoint to extend your flying range or maintain visual line of sight (VLOS) when flying in obstructed areas.
Key Features and Setup
Inside the box, users will find:
- The repeater module itself
- Two sets of antennas (four for each side)
- Power and USB cables
- A setup card from Caddx
The module features:
- 5.1 to 5.3 GHz antennas linked to the VRX (video receiver)
- 5.5 to 5.8 GHz antennas linked to the VTX
- USB port for updates
- Power input range of 9 to 26 volts
- Compact aluminum housing
Setup Process
Setting up the repeater involves the following steps:
- Connect power and antennas to the module.
- Bind your goggles to the VRX side and your drone to the VTX side.
- Ensure both devices remain within line of sight of the repeater.
Performance Insights
One of the major considerations when using the repeater is the latency introduced into the system. Ian conducted tests revealing a latency increase of approximately 13 milliseconds when using the repeater compared to direct communication between the goggles and the drone.
Use Cases: Who is this for?
The Caddx Avatar HD Repeater is particularly beneficial for:
- FPV pilots aiming for longer flight distances.
- Users needing to navigate structures where maintaining VLOS is challenging.
- Individuals with mobility challenges who wish to operate drones from a fixed location.
Limitations to Consider
While the repeater offers significant advantages, it does come with limitations:
- Does not support HDMI output or DVR functionality.
- Requires specific antennas for goggles that are not included in the package.
- Only compatible with the Avatar HD system, not supporting other RC control links.
Final Thoughts
Ian concludes that the Caddx Avatar HD Repeater is a valuable tool for specific applications within the FPV community. While it may not suit racing environments due to the added latency, it opens up new possibilities for long-distance flights and complex navigational tasks.
FAQ
Does the repeater support HDMI output?
