The DIAMOND SRH770S dual band antenna (SMA) – SMA dual band portable antenna Frequencies: 144 \/ 430MHz Max. Power: 10 W Length: 70 cm Weight: 45 g<\/strong> is a commercial-grade, high-gain telescopic transceiver antenna precision-engineered to deliver secure voice synchronization, flexible multi-band spectrum tracking, and professional signal path tracking across active portable networks. Manufactured by Diamond Antenna, an international standard in high-performance RF engineering, this premium portable radiator overhauls low-efficiency factory rubber duck whips that limit communication range in localized dead zones. It stands as an essential operational procurement asset for industrial facility logistics, wilderness search and rescue coordination, multi-terrain event security crews, and high-volume B2B radiocommunication hardware accessory wholesale distribution channels looking to source original factory-genuine active components.<\/p>\n

The advanced internal RF core of this high-compliance hardware element is optimized to operate seamlessly across dual allocation bands, targeting frequencies: 144 \/ 430MHz<\/strong> (VHF 2-meter and UHF 70-centimeter bands) with high resonance efficiency. This wideband agility yields low voltage standing wave ratios (VSWR) across standard commercial and amateur channels, protecting internal handheld transmitter power amplifiers from destructive reverse-power thermal accumulation. By projecting an expanded radiation pattern focused cleanly toward the horizon, the telescopic element maximizes signal path propagation over complex field environments, dense warehouses, and concrete industrial infrastructures while safely managing a max. power: 10 W<\/strong> operational power load limit.<\/p>\n

Housed inside a premium, low-friction stainless steel telescopic column, the structural frame extends smoothly to a full operational length: 70 cm<\/strong> to optimize long-range fringe signals, yet collapses easily for discrete low-profile transport. Despite its deep physical clearance, it registers a lightweight net weight: 45 g<\/strong> to eliminate wrist fatigue and structural mechanical torque on the host transceiver’s top casing during continuous hand manipulation. Terminating in a standardized high-retention SMA<\/strong> male connection port with a heavy-duty threaded locking collar, this turnkey portable antenna eliminates the risk of intermittent signal drops and guarantees absolute field deployment readiness for your handheld fleet.<\/p>\n
