The Diamond SG9600 is a versatile, high-performance triband mobile antenna engineered for vehicular installations operating across the 50MHz (6-meter), 144MHz (VHF), and 430MHz (UHF) amateur bands. Combining three frequency allocations into a single, streamlined vertical element, this antenna allows multi-band operators to maximize their communication capabilities without mounting multiple whip systems on a single vehicle. The lower base section terminates in a standard MP (PL-259 compatible male profile) RF connector, ensuring a rigid mechanical and electrical connection to standard heavy-duty mobile coaxial mounts.
The radiating element utilizes sophisticated electrical wavelength configurations tailored for each operating band to optimize radiation efficiency and patterns. On the 50MHz band, it functions as a 1/4 wave element (specifically tuned for 51 to 52MHz FM). On the 144MHz VHF band, it transitions to a 1/2 wave radialless configuration, delivering a gain of 2.15dBi. For the 430MHz UHF band, the system utilizes a 2x 5/8 wave radialless architecture to boost the gain to 5.2dBi. The radialless design on both VHF and UHF bands ensures stable performance independent of the vehicle’s metal ground plane. Rated for a maximum power threshold of 60W FM (total), this antenna maintains a Voltage Standing Wave Ratio (VSWR) of less than 1.5:1 at resonance.
