Product Overview
The 138-960MHz 4 Way Wilkinson Power Splitter is a high-performance, critical-grade component designed specifically for Public Safety Systems. Its wide frequency coverage (VHF/UHF/700/800/900MHz) and high-visibility Red Color make it an essential part of BDA (Bi-Directional Amplifier) and DAS infrastructures. Built with an IP65 enclosure for indoor and outdoor versatility, this splitter ensures high isolation and low insertion loss to maintain reliable emergency communication coverage.

Frequently Asked Questions
- Q1: Why is the red color significant for Public Safety systems?
- A: In Public Safety DAS (Distributed Antenna Systems), Red Color housing is an industry standard used to quickly identify critical communication equipment. This helps fire marshals and maintenance crews distinguish these systems from commercial cellular networks during inspections or emergencies.
- Q2: How does the Wilkinson design improve isolation in Public Safety networks?
- A: Wilkinson splitters feature internal isolation resistors. For this 4-way model, it provides at least 16dB isolation between ports. This prevents signal interference or feedback between different radio devices connected to the same antenna system, which is crucial for clear emergency voice traffic.
- Q3: Can this splitter be used in outdoor or damp environments?
- A: Yes. The device is rated IP65 grade, providing protection against dust and low-pressure water jets. Combined with a wide operating temperature range (-30 to +70℃), it is reliable for rooftop installations or parking garage deployments.
- Q4: Does your company offer OEM or custom frequency tuning?
- A: Absolutely. We provide professional OEM/ODM services. We can adjust frequency bands, modify connector types (such as 4.3-10 for low PIM), or change the mechanical dimensions to meet your specific project requirements.
- Q5: What other Public Safety DAS products do you offer?
- A: We provide a full range of solutions including VHF/UHF Power Tappers, Directional Couplers (3-30dB), and 6-way Power Dividers, all specifically tuned for the 138-960MHz Public Safety spectrum.
