Range gets the attention, but what most pilots actually want is confidence: a stable control link and a clean video feed where the stock connection starts to feel “on the edge”.
The key difference with !ROCKSOLID is that it boosts both directions of the link. Many solutions only boost the remote controller side, which can help, but it’s only half the connection.
Simple analogy: boosting only the controller is like speaking louder to the aircraft—useful—but the aircraft still has to “speak back” with limited power. When both the controller and the aircraft are boosted, the link is more balanced, which is where the “rock solid” experience comes from.
!ROCKSOLID Dual-Band Bi-Directional Signal Booster Kit (2.4/5.8GHz) is designed to improve link stability and usable range for DJI drones and controllers by strengthening both ends of the connection. The result is a cleaner, more consistent control and video link across the flights you actually fly—especially in interference-heavy areas and around terrain.
This is a boards-based kit (not a DIY “bag of components”). A full kit includes two booster boards (one for the aircraft and one for the remote controller), two signal cables (one per board, connector types matched to your drone/RC), a complete wire set, an RC power regulator with EN/relay (cuts power to the RC booster when the controller is off), and an RC heatsink.
Half kits are available for customers who use multiple drones with the same remote controller (e.g., aircraft-only), or for boosting an additional controller (RC-only).
Installation places the booster in-line between the device RF port and the antenna: device RF port → signal cable → Booster IN, and original antenna → Booster OUT. Power wiring is straightforward: the aircraft module uses 4 wires and the RC module uses 5 wires (includes EN for the relay).
Important: Cooling is required. The amplifier generates heat during operation and must have passive cooling with solid thermal contact before use.
Important: Always connect the antenna before power. Ensure the antenna is connected to the booster output before applying power, and do not disconnect the antenna while the booster is powered.
