HF block antenna


Due to its design, the RF block antenna is particularly suitable for applications with limited space. It is designed as a frame antenna and is sealed watertight by a robust plastic case (available in protection class IP65 and IP 30). It is suitable for use in metallic environments. In order to offer the optimal solution for each application, the RF block antenna is available with different cable outputs and different cable lengths (sizes not listed are available on request).
