R-40W

2.4G Directional Antenna

Product Description

The special antenna for 2.4GHz signal can effectively and reliably enhance the ability of signal transmission or reception, and has a high directional characteristic of 4-6dBi, which has a very good effect on the use environment where the selected azimuth is required.

Performance Introduction

Application Scenarios


  • Wireless Microphone Systems in Education/Conference Settings

    Ideal for use with systems like the IMIC-6D, enhancing signal stability and coverage—especially effective in large classrooms, lecture halls, and multi-functional venues where directional transmission is needed.

  • Directional Audio Transmission in Meeting Rooms or Auditoriums

    With a high directional gain of 4–6dBi and a 95° horizontal beam width, this antenna is well-suited for transmitting signals toward a specific area, such as a speaker podium or front stage.

  • Long-Distance Wireless Bridging

    Useful in campuses or office buildings to bridge audio systems across different floors or buildings, improving signal reception and stability over distances.

  • Environments with High Interference

    In noisy or interference-prone environments (e.g., trade shows, urban classrooms), its 85% efficiency and 22dB front-to-back ratio help reduce unwanted signal interference and enhance communication clarity.

  • Fixed Wireless Installations

    Lightweight (only 85g) and equipped with an N-type male connector, this antenna is ideal for permanent mounting on walls or ceilings for long-term deployments in wireless audio or control systems.
