433MHz 2.5dBi Fiberglass Antenna Omnidirectional IP67 20×300

The BGS-AN0433-20300W is a high‑performance omnidirectional antenna designed specifically for the 433MHz ISM band. With a thicker (Φ20mm) and longer (300mm) fiberglass radome, it delivers significantly improved gain and efficiency while maintaining true 360° coverage. Featuring a typical gain of 2.5dBi and efficiency approaching 70%, it is an excellent choice for long‑range, low‑power applications such as IoT, wireless meter reading, security systems, and industrial control.
