The 433MHz LoRa Antenna with SMA Male Connector is a high-gain, flexible rubber duck antenna engineered specifically for long-range Sub-1GHz wireless communication applications. Operating at the unlicensed 433 MHz ISM frequency band, this antenna delivers stable signal transmission, enhanced receiver sensitivity, and extended coverage range for LoRa modules, RF transceivers, and IoT gateways.

Featuring a standard SMA Male connector (with internal threads and a center pin), it screws directly into SMA Female chassis jacks on SX1278 LoRa modules, HC-12 wireless transceivers, CC1101 modules, and custom RF enclosures. The flexible outer rubber casing protects the internal helical coil antenna against bending and environmental wear, making it reliable for both indoor and outdoor IoT installations.

Key Features and Benefits

• Optimized for 433 MHz Band: Designed specifically for 433 MHz LoRa and RF applications to maximize signal propagation and minimize VSWR losses.

• Standard SMA Male Connector: Threaded brass connector with inner pin ensures tight, low-loss RF connection with SMA Female sockets.

• Omnidirectional Signal Coverage: Provides full 360-degree radiation coverage for uniform wireless transmission in all horizontal directions.

• Durable & Flexible Rubber Sheath: High-durability rubber housing shields internal antenna element from mechanical strain and impact.

• Plug-and-Play Compatibility: Directly compatible with popular 433MHz RF hardware like SX1278, Ra-02 LoRa modules, HC-12, and RF telemetry systems.

Technical Specifications

How to Use

1. Verify Connector Gender: Ensure your LoRa transceiver or RF board features an SMA Female port (outer threads with a center receptacle).

2. Mounting: Thread the SMA Male connector of the antenna onto the SMA Female port of your device and tighten firmly by hand. Do not over-tighten with tools.

3. Positioning: Orient the antenna vertically for optimal 360-degree horizontal RF signal coverage and line-of-sight propagation.

4. Testing: Test transmission and reception range using your microcontroller setup (e.g., Arduino or ESP32 with SX1278 module).
