The Diamond SRH771 is a commercial-grade, high-performance dual-band handheld transceiver antenna engineered to significantly optimize signal transmission and reception quality for portable radio amateurs, field security personnel, and tactical communication teams. Measuring exactly 40 cm in length and weighing a lightweight 38 grams, this flexible vertical whip antenna is built with a high-durability black polymer chassis designed to reduce mechanical stress on the radio’s antenna port. It serves as an exceptional high-efficiency hardware upgrade for operators requiring extended coverage and robust build quality over standard stock antennas.
Engineered for broad multi-band versatility, the SRH771 provides optimized transmission (TX) performance on the core amateur 144 MHz (VHF) and 430 MHz (UHF) bands, sustaining a maximum power rating of up to 10 Watts. For advanced monitoring operations, the antenna features an extended wideband reception (RX) capability, enabling clear, high-sensitivity monitoring of the commercial Air Band, as well as the 150 MHz, 300 MHz, 450 MHz, and 900 MHz frequency spectrums. The structural base architecture features an enhanced cylindrical reinforcement carrying the official screen-printed orange Diamond Antenna insignia, terminated with a high-retention male SMA connector interface to ensure a low-loss, stable electrical lock.
