Product Introduction

1. Wideband Coverage, Optimized for VHF Communication

Covering the entire VHF band from 136-174MHz, suitable for signal coupling and monitoring in professional walkie-talkies, dispatch systems, and other narrowband communication equipment.

2. Multiple Coupling Values Available, Flexible Adaptation to System Needs

Offering multiple coupling value models including 5dB, 6dB, 7dB, 10dB, 15dB, and 20dB, allowing flexible selection based on signal distribution requirements, supporting precise signal sampling and monitoring.

3. Low Insertion Loss and High Isolation, Ensuring Signal Quality

Insertion loss as low as ≤0.3dB (20dB coupling model), and isolation up to ≥38dB, effectively reducing signal attenuation and suppressing interference, ensuring stable system operation.

4. High Power Handling Capability, Rugged and Durable

Supports an average power of 200W, VSWR≤1.25, impedance 50Ω, adopts an N-Female interface, and features a black metal casing, suitable for long-term high-load operating environments.

5. Indoor protective design with strong environmental adaptability. IP60 protection rating, dustproof and splashproof, operating temperature -30℃~+65℃, humidity 5%-95%, suitable for various indoor communication equipment rooms and equipment rooms.
