Spring Bullets

SV Microwave’s Spring Bullets are engineered to ensure exceptional RF performance across high-frequency and demanding applications. Their spring-loaded, compressible design eliminates gaps during gang mating. This maintains consistent electrical performance throughout the entire range of compression. These bullets are ideal for aerospace, military, instrumentation, and satellite communications applications. Several different standard lengths are available in distribution with customized lengths available upon request. These bullets provide unparallelled signal performance while maintaining a simplified and user-friendly design.
