Professional Ultra-Compact VHF/UHF Dual-Band Radiating Infrastructure
The Diamond SRJF10 is a commercial-grade, multi-band portable vertical antenna engineered to deliver dependable radio frequency transmission and wide-spectrum voice reception for professional handheld transceivers. Structurally optimized as an electrically calibrated 1/4-wave (1/4λ) whip assembly, this high-performance antenna enables dual-band transmission (TX) capabilities across the key 144 MHz (VHF) and 430 MHz (UHF) spectrums. It serves as an immediate, space-saving utility asset for close-quarters security details, emergency coordination command positions, public safety units, and high-volume B2B radiocommunication accessory wholesale distribution channels across European markets.
Beyond its core transmission bands, the advanced internal coil design features wideband reception (RX) capabilities across an expansive set of frequencies, tracking signals seamlessly across 120, 150, 300, 450, 800, and 900 MHz. This makes it a powerful asset for multi-agency scanner monitoring and public utility oversight. The technical layout supports a 6 W maximum applied power rating, perfectly matching the output thresholds of professional commercial walkie-talkies. Measuring a low-profile 7.2 cm in length and weighing an ultra-lightweight 18 g, the antenna significantly reduces structural torque on the terminal’s antenna chassis port, preventing expensive hardware cracks during intensive physical maneuvers.
To eliminate insertion loss and preserve absolute signal path integrity, the antenna is factory-terminated with an industry-standard SMA-Female mechanical interface connector. This high-conductivity connector establishes a flush, vibration-proof electrical bond directly onto modern handheld transceiver bases, maintaining a highly tuned, nominal characteristic impedance of 50 Ohms to protect internal transmitter amplifier blocks from accidental power reflections. This rugged, compact vertical whip ensures complete operational fleet readiness across demanding industrial, logistical, and outdoor environments.
