Key Features
- 433 MHz Optimized: Precisely tuned for the 433 MHz ISM band, ensuring maximum signal strength and minimal return loss for LoRa, RF remote, and telemetry systems.
- 2.5 dBi Gain: Enhanced omnidirectional gain over standard 0 dBi stub antennas, extending communication range significantly in all horizontal directions.
- Folding / Swivel Design: 90 degrees adjustable hinge joint allows the antenna to be folded flat for transport or angled for optimal radiation pattern and clearance in tight enclosures.
- Omnidirectional Coverage: 360 degrees horizontal radiation pattern eliminates the need for precise directional alignment - perfect for mobile and multi-node networks.
- 50 Ohm Impedance Matched: Standard 50-ohm impedance ensures direct compatibility with most RF modules, transceivers, and SMA-equipped development boards.
- Compact & Lightweight: Small form factor rubber ducky style antenna is easy to mount on enclosures, gateways, and portable devices.
- Wide Temperature Range: Operates reliably from -40 degreesC to +85 degreesC, suitable for outdoor and industrial deployments.
Why Choose This Antenna?
- 100% authentic from trusted RF component suppliers
- Noticeable range improvement over PCB trace and chip antennas at 433 MHz
- Folding mechanism ideal for portable, field-deployable, and space-constrained designs
- Plug-and-play SMA connection - no soldering or impedance matching network required
- 1-5 day shipping, 7-8 day delivery from our Bengaluru warehouse
- Expert RF and wireless technical support included
Compatible Modules & Platforms
- LoRa Modules: SX1278, Ra-02, RFM95W, E32 series (433 MHz variants) - ideal for long-range LoRa/LoRaWAN nodes and gateways.
- RF Transceiver Modules: CC1101, SI4432, HC-12, nRF905 - enhances range for serial wireless links and sensor networks.
- Remote Control Receivers: 433 MHz ASK/OOK receiver modules (e.g., RXB6, SYN480R) for garage door openers, alarm systems, and RC applications.
- Development Boards: Any Arduino, ESP32, STM32, or Raspberry Pi setup with an SMA-equipped 433 MHz radio module.
- Commercial Gateways: 433 MHz ISM band IoT gateways and repeaters requiring external antenna upgrade.
Project Ideas
- LoRa IoT Sensor Network: Deploy long-range wireless sensor nodes for agriculture, weather monitoring, or smart city applications. The 2.5 dBi gain and omnidirectional pattern ensure reliable multi-kilometer links between nodes and gateways.
- Home Automation RF Hub: Build a centralized 433 MHz receiver to capture signals from wireless door sensors, motion detectors, and smart switches. The folding antenna fits neatly inside or on top of an enclosure.
- Long-Range Remote Control: Extend the range of RC transmitters and receivers for robotics, drones, or industrial remote operation. Upgrade from a basic wire antenna to achieve significantly better link budget.
