The Diamond SG-9500M premium tri-band mobile antenna is a commercial-grade vehicular whip radiator precision-engineered to deliver outstanding multi-band transceiver tracking, high-efficiency signal propagation, and structural durability across professional mobile radio networks. Built to handle intensive transit conditions, this high-performance mobile antenna completely eliminates the need for external chassis ground planes due to its sophisticated, fully integrated radialless engineering. It serves as an essential logistics procurement component for multi-agency emergency communication vehicles, tactical field coordination transport, mobile scanning rigs, and high-volume B2B radiocommunication accessory wholesale distribution networks looking to maximize signal penetration over specialized frequency portfolios.
The advanced internal electrical architecture of the Diamond SG-9500M features a highly complex phasing matrix operating dynamically across three separate bands: a 1/2 wave C-Load radialless structure at 144 MHz (2-meter), a 2x 5/8 wave C-Load radialless layout at 430 MHz (70-centimeter), and a dense 5x 5/8 wave C-Load radialless configuration at 1200 MHz (23-centimeter). This layout compresses the radiation angles toward the horizon to yield an impressive omnidirectional signal gain profile of 3.15 dB at 144MHz, 6.3 dB at 430MHz, and a massive 9.7 dB at 1200MHz. Measuring exactly 1.00 meter in length and weighing a well-balanced 320 grams, this rugged whip minimizes torque strain on mobile mount bases during high-velocity maneuvers. Designed to maintain a stable voltage standing wave ratio (VSWR of less than 1.5:1) across a standard 50 Ohms nominal impedance, it manages a **100 Watts maximum power rating on FM (144/430MHz), 50 Watts on FM (1200MHz)**, with a 100W total ceiling. The antenna base comes terminated with a factory-milled MP Type (PL-259 Male UHF) connector, ensuring immediate technical system alignment, solid mechanical coupling, and total fleet deployment readiness.
