Frequently Asked Questions
- Q1: What are the main advantages of the 340-2700MHz frequency range?
- A: This ultra-wideband coverage allows a single component to support everything from UHF/TETRA frequencies up to standard cellular 4G LTE bands, simplifying inventory and system complexity for DAS and IBS.
- Q2: How does the 300W average power rating benefit high-capacity sites?
- A: With a high power handling capacity of 300 Watts, these couplers can be safely used near the BTS source where signal levels are highest, ensuring long-term reliability without overheating or signal degradation.
- Q3: Is this directional coupler suitable for outdoor installations?
- A: Absolutely. It features an IP65 waterproof rating and a wide operating temperature range (-30°C to +75°C), making it ideal for rooftop installations and other challenging outdoor environments.
- Q4: Why is "High Isolation" a key feature for this series?
- A: High isolation (up to ≥32dB) ensures that the coupled path and the isolated path do not interfere with each other, maintaining signal purity and protecting equipment from unwanted reflected power.
- Q5: What is the significance of the 200C Red color?
- A: The distinct 200C Red finish serves as a visual identifier for easy monitoring and maintenance within dense equipment racks and distributed antenna system networks.
