This 433 MHz RF rubber antenna is designed for wireless communication systems operating in the 433 MHz ISM band, which is commonly used for remote controls, sensors, and IoT applications. With a gain of approximately 2.5 dBi, it offers a good balance of coverage and compact form factor for typical short- to medium-range wireless links.

Key Features:

  • Frequency Range: 433 ± 5 MHz – optimized for 433 MHz RF modules and devices.

  • Gain: ~2.5 dBi – moderate signal amplification suitable for many wireless applications.

  • VSWR: ≤ 1.5 – ensuring efficient radiation with minimal reflections.

  • Impedance: 50 Ω – standard RF antenna interface.

  • Connector: Typically SMA or SMA-type for simple plug-and-play connection to RF modules.

  • Compact Design: Under ~50 mm long, lightweight and durable.

  • Polarization: Vertical – suitable for general omnidirectional use.

Applications:
Whether you’re building RF remote systems, sensor networks, home automation gear, or microcontroller communication links, this antenna provides improved signal strength and reliability compared to basic PCB or chip antennas.
