433MHz 5dBi Omnidirectional Antenna Fiberglass Antenna 18.5×1000
Product Introduction
The BGS-AN0433-181000G is a professional‑grade, high‑gain omnidirectional antenna engineered for the 433MHz ISM band. Featuring a slim 1‑meter fiberglass radome (Φ18.5×1000mm), it delivers an impressive 5dBi gain with ≈80% efficiency and an excellent <1.5 VSWR. This antenna is designed for long‑range, demanding wireless applications where maximum link budget, reliable omnidirectional coverage, and rugged outdoor durability are essential.
