The Diamond RH771 dual-band portable antenna is a commercial-grade, high-performance tactical radiation element engineered to drastically improve signal transmission and wideband monitoring efficiency on handheld transceivers or portable scanners. Measuring exactly 40 cm in length and weighing an ultra-lightweight 42 grams, this premium flexible whip antenna is structurally optimized to balance mechanical resilience with top-tier RF performance. It functions as an essential, high-rotation operational procurement accessory for field telemetry teams, emergency coordination personnel, security operations, and high-volume B2B radiocommunication distribution networks across European markets.
The internal electrical engineering of the RH771 delivers precise resonance configurations, acting as a highly efficient 1/4λ element on 144 MHz (VHF) and a 1/2λ element on 430 MHz (UHF) for dedicated transmission (TX) workflows. Beyond standard dual-band transmission, the advanced architecture supports extended wideband reception (RX) tracking across 150, 300, 450, and 900 MHz spectra, making it perfect for multi-agency signal analysis. Rated for up to 10 Watts maximum input power with a nominal 50-Ohm system impedance, it yields an impressive 2.15 dB signal gain on the UHF band to pierce through dense terrain. Pre-terminated in a standardized, industrial-grade BNC-Male plug connector base, it ensures an absolute mechanical connection and immediate fleet deployment readiness.
