Signal amplifier for remote control A151S-Raptor SR for RC2

Signal amplifier A151S-Raptor SR for RC2

The A151S-Raptor SR antenna is 4Hawks' most powerful solution, specifically designed for the DJI RC2 controller. This passive antenna replaces the standard internal and external components of the transmitter, transforming it into a high-performance tool for ultra-long-range flights.

Main characteristics

• Maximum Power: Designed specifically to optimize DJI RC2 controller communication.
• Distance increase: provides an extension of the drone's range up to 4 times.
• Dual-band operation: simultaneous support for 2.4 GHz and 5 GHz frequencies.
• Antenna type: passive design that does not require external power sources or additional amplifiers.
• Communication quality: Significant improvement in video transmission stability throughout the flight.

What is included in the kit?

• Raptor range booster antenna
• Stainless steel mounting kit
• 4 RP-SMA (male) RG316 pigtails, black
• 2 pigtails SMA R/A - U.FL (1.13)
• 2 pigtails SMA - U.FL (1.13)
• Tool kit: two screwdrivers (Torx T6 and Philips) and an 8 mm wrench
• Additional tools

 

Advantages

1. Fourfold increase in range

By replacing two small internal and two external omnidirectional antennas with four large, powerful dual-band antennas, you get a huge increase in control and data transmission distance.

2. Simultaneous operation in two bands

The device effectively operates on both 2.4 GHz and 5 GHz frequencies simultaneously. This allows the system to automatically select the cleanest communication channel, minimizing the impact of urban interference and radio noise.



 

3. Dual signal polarization

The unique design supports both horizontal and vertical polarization. This extends coverage and makes the connection more stable even when the drone maneuvers or changes its orientation in space.

4. Passive amplification without interference

The increase in range is achieved solely due to the geometry and materials of the passive antenna. The absence of electronic amplifiers eliminates the appearance of unnecessary noise in the signal and does not require additional battery charging for the antenna unit to operate.

5. Improved video stream stability

Upgraded ports and antenna arrays provide much higher quality streaming video. The picture remains clear and smooth even at extreme distances, where standard antennas usually lose signal.

Technical specifications

• Materials: Samsung ABS, polyurethane, aluminum, stainless steel, nylon, PTFE PCB
• Weight: ~ 520 g (antenna with mount)
• Dimensions: 29.2 x 18.2 x 2.1 cm
• Connection type: 4 ports RP-SMA socket
• Adjustment: 3 tilt positions

Scope of application

• Professional video shooting: for work on objects where maximum departure from the starting point is required without loss of Live view quality.
• Search and rescue operations: expanding the coverage area allows you to survey large areas faster.
• Flights in areas with high levels of interference: dual polarization and a narrow beam help to "break through" the radio curtain within the city.

Why is it worth buying the A151S-Raptor SR antenna?

A151S-Raptor SR is the choice of those who are not ready to put up with the limitations of a standard controller. Although the installation requires modification of the case (drilling SMA holes), this process is fully justified by the result. You get a comprehensive solution with tools included, which turns the DJI RC2 into a professional control station with a communication range that exceeds the factory capabilities several times.
