Description

a 433 MHz 5 dBi rubber duck antenna with an SMA male connector, you're likely working on IoT, LoRa, or RF telemetry applications—great choice for compact, omnidirectional coverage. Here's a breakdown of what these antennas typically offer: 📡 Key Specifications - Frequency: Centered around 433 MHz (typically 425–439 MHz) - Gain: 5 dBi nominal - Impedance: 50 Ω - VSWR: ≤ 1.5 for efficient matching - Polarization: Vertical - Radiation Pattern: Omnidirectional (360° horizontal) - Power Handling: Up to 100 W - Connector: SMA Male (some models use RP-SMA, so double-check compatibility) 🛠️ Mechanical Details - Mounting: Terminal mount, often with a tilt-and-swivel joint - Length: ~170–200 mm - Color: Usually black - Material: ABS housing with internal helical or whip element - Operating Temp: –40 °C to +85 °C (varies by model) 🔍 Notable Options - Eteily 433 MHz 5 dBi Rubber Duck Antenna: SMA male, movable joint, rugged build—great for LoRa and telemetry - Signity RF Solutions Rubber Duck Antenna: Based in New Delhi, offers a 433 MHz 5 dBi model with direct ground lightning protection - NETBOON 5 dBi RP-SMA Antenna: Widely used for Wi-Fi and LTE, but check connector type (RP-SMA vs SMA)
