Description

The LWC-2400 is a compact, high-performance rubber duck antenna engineered for the 2.4GHz industrial, scientific, and medical (ISM) band. Its design centers on a 5dBi gain element housed within a durable ABS and rubber casing, providing a robust solution for outdoor and indoor wireless systems. The integrated right-angle RP-SMA plug offers installation flexibility, allowing the antenna to be oriented optimally to reduce cable strain and fit into enclosures.

With a standardized 50-ohm impedance and vertical polarization, this antenna ensures seamless integration with a wide array of 2.4GHz transceivers, including ESP32/ESP8266 Wi-Fi modules, nRF24L01+ boards, and commercial access points. Its omnidirectional radiation pattern in the horizontal plane (360°) combined with a moderate vertical beamwidth delivers reliable coverage for IoT sensor networks, smart home devices, and wireless telemetry links where consistent connectivity is critical.

Key Features

  • Enhanced 2.4GHz Range: The 5dBi gain boosts signal strength for longer-distance Wi-Fi, Bluetooth, and Zigbee connections compared to stock antennas.
  • Flexible Right-Angle Connector: The RP-SMA plug features a right-angle, foldable design for easy routing and installation in tight spaces or enclosures.
  • Durable Outdoor-Ready Build: Constructed with ABS plastic and a rubber duck tip to resist physical impacts and operate across a wide -30°C to 60°C temperature range.
  • Optimized RF Performance: 50-ohm impedance matching and low VSWR ensure maximum power transfer from your transmitter with minimal signal loss.
  • Plug-and-Play Compatibility: Directly connects to any RP-SMA female jack on wireless modules, routers, or IoT gateways without requiring external adapters.
  • Lightweight and Compact: Weighs less than 20g with dimensions of 200mm length and 13mm diameter, making it easy to mount on devices or enclosures.

Applications

  • Wi-Fi Router & Access Point Enhancement: Upgrade the antenna on ESP32-based IoT gateways, Raspberry Pi Wi-Fi adapters, or commercial routers to extend network coverage.
  • Bluetooth & BLE Device Networks: Improve the range and reliability of Bluetooth Low Energy beacons, audio devices, or sensor hubs in smart home and industrial environments.
  • Zigbee & Thread Mesh Networks: Deploy on Zigbee coordinators or end-devices to strengthen links in home automation and industrial wireless sensor networks.
  • 2.4GHz ISM Band Prototyping: Use as a reliable antenna for nRF24L01+, ESP8266, or other 2.4GHz RF module development boards during testing and deployment.
  • Wireless Telemetry & IoT Sensor Links: Provide a durable, outdoor-capable antenna for remote environmental monitoring, asset tracking, and agricultural sensor systems.

Frequently Asked Questions

What devices is this RP-SMA antenna compatible with?

This antenna is compatible with any wireless module, router, or gateway featuring a female RP-SMA jack. This includes many ESP32 and ESP8266 development boards, Raspberry Pi Wi-Fi adapters, USB dongles, and commercial access points that use the RP-SMA connector standard for 2.4GHz communications. Ensure your device's port is RP-SMA (reverse polarity SMA) and not standard SMA for a proper fit.

How do I install and orient the right-angle connector?

Simply screw the RP-SMA plug clockwise into the female jack on your device until snug. The right-angle design allows the antenna to fold parallel to your device's PCB, saving vertical space. For optimal signal propagation, position the antenna vertically. Avoid bending the cable sharply at the connector base to prevent wire fatigue. The foldable hinge lets you adjust the angle post-installation for best placement in an enclosure.

What is the actual gain, and how does it improve my wireless range?

The antenna provides a peak gain of 5 dBi. Gain represents how effectively the antenna focuses radiated power compared to an isotropic radiator. A 5 dBi gain can significantly extend the usable range of your 2.4GHz link compared to a lower-gain (e.g., 2 dBi) stock antenna, improving signal strength and reliability for Wi-Fi, Bluetooth, or Zigbee applications. Actual range improvement depends on transmitter power, receiver sensitivity, and environmental obstacles.
