IS-B50 Coaxial RF Surge Protectors

PolyPhaser IS-B50 Coaxial RF Surge Protectors are designed to protect against lightning events and are ideal for HF, UHF, and VHF radios. These protectors cover a broad 1.5MHz to 1000MHz frequency range and feature N-Type and UHF connectors, high-power handling up to 3kW, and 20kA industry-leading surge rating. The IS-B50 coaxial RF surge protectors are CE and RoHS compliant, offering flexible mounting options and versions for nuclear EMP protection. Typical applications include ham radio operators, land mobile communications, emergency response, SCADA, and public safety systems.
