Product Description
VHF Digital Repeater System 150MHz Digital Band Selective Repeater System for Customized Use
Product Overview
Digital VHF BDA band selective repeater system designed to extend coverage range of Very High Frequency (VHF: 30-300 MHz) digital radio communication systems.
Core Functions
- Signal Reception: Receives weak/attenuated digital radio signals (DMR, dPMR, P25 Phase 2) within VHF band from user equipment
- Digital Processing: Decodes, regenerates, and error-corrects digital signals (unlike analog repeaters that amplify noise)
- Signal Retransmission: Rebroadcasts cleaned digital signal at higher power to distant or obstructed areas
Key Advantages
- Extended Coverage: Overcomes terrain obstructions and VHF range limitations (~5-50 km line-of-sight)
- Signal Integrity: Regeneration prevents noise/error accumulation, maintaining voice/data quality
- Spectral Efficiency: Supports digital modulation, enabling multiple users on one frequency
System Features
- Digital filtering supports adjustable bandwidth, each band supports three sub-bands
- Each sub-band features independent on/off control and gain adjustment
- Donor signal monitoring for easy optimization and troubleshooting
- Intelligent algorithm to prevent UL interference
- Self-control to minimize interference for new rollout e-Node B
