RF Solutions 433/868MHz Puck Antenna with SMA Male Connector

The RF Solutions 433/868MHz Puck Antenna is a compact and robust dual-band antenna designed for reliable wireless communication in demanding environments. Featuring a high IP67 rating, it is fully protected against dust ingress and can withstand immersion in water up to one metre deep for 30 minutes, making it ideal for outdoor or industrial applications where exposure to the elements is a concern.

Constructed from durable ABS and rubber, the antenna is designed for longevity. Its rugged screw-fix mounting ensures a secure and stable installation, resisting vibration and mechanical stress. The unit comes pre-fitted with a generous 1.5-metre cable terminated with a standard SMA male connector, providing flexibility for integration with a wide range of radio modules, data loggers, and IoT devices.

This antenna operates across the 433MHz and 868MHz license-free ISM bands, which are commonly used for telemetry, remote control, smart metering, and industrial automation. Its omni-directional radiation pattern ensures consistent signal coverage in all horizontal directions, simplifying installation as precise alignment is not required. With a gain of 2dB, it offers a useful improvement in signal strength over a basic dipole, extending the effective range of your wireless system.
