The RFMAX RBCO-433-2-S-C is a rugged, base-loaded coil antenna engineered for reliable operation in 433 MHz unlicensed ISM and IoT applications. Its standard NMO mounting system and compact spring-whip design make it well suited for installation on vehicles, industrial equipment, outdoor enclosures, and other field-deployed systems.
Optimized for 433 MHz, the RBCO-433-2-S-C delivers a typical VSWR of 1.5:1, 75% radiation efficiency, and 1 dBi peak gain. The base-loaded coil architecture provides efficient UHF performance in a compact form factor, while the integrated spring helps reduce strain caused by incidental contact or movement.
