433MHz Antenna SMA Male
The 433MHz Antenna with SMA Male connector is a 3dBi rubber-duck whip antenna tuned for the 433MHz ISM band used by most low-cost RF modules. Anyone comparing the 433MHz SMA antenna price in Bangladesh will find this a simple but essential upgrade for wireless link reliability. Just screw it onto the SMA socket of your RFM69, CC1101, STX882, RXB6 or similar module and the working range of your radio link can improve dramatically compared with a bare module antenna. It is a must-have for Arduino remote controls, wireless sensor networks, gate and garage door openers, weather stations and DIY IoT devices. Buy the 433MHz SMA male antenna in Bangladesh from Tekko and enjoy a clean, stable RF signal in every project.
Key Features:
• Tuned for the 433MHz ISM band, including 433.92MHz devices
• SMA male connector fits standard SMA female bulkheads and module sockets
• Approx 3dBi gain with 50 ohm impedance for a solid RF link
• Flexible rubber-duck whip body is compact, light and durable
• Omnidirectional radiation pattern covers all around the antenna
• Can significantly extend the range of 433MHz transmitters and receivers
• Works with Arduino, ESP8266/ESP32, Raspberry Pi and dedicated RF ICs
