Frequently Asked Questions
- Q1: Why is the Log Periodic Antenna (LPDA) preferred for DAS installations?
- The Log Periodic Antenna provides a highly consistent performance across an extremely wide frequency band (698-2700MHz). This allows a single antenna to support multiple generations of cellular technology (2G/3G/4G/LTE) within a DAS network, reducing equipment footprint and complexity.
- Q2: How does the 10dBi high gain improve indoor signal coverage?
- A high gain of 10dBi allows the antenna to project signal further and more effectively through indoor obstructions. This is essential for In-building Solutions where maintaining strong signal strength in large open areas or long corridors is a priority.
- Q3: What is the significance of the Front-to-Back (F/B) ratio of ≥18dB?
- An F/B ratio of ≥18dB indicates that the antenna is highly directional, focusing energy forward while minimizing signal leakage to the rear. This helps in reducing interference with other nearby cell sites and improves the overall carrier-to-interference ratio of the system.
- Q4: Is the MLPA-727-SS-NF compatible with standard mounting hardware?
- Yes, the antenna is designed to be fixed with a nut, providing a secure and straightforward installation process. Its relatively low weight of 0.8kg and compact dimensions make it easy to integrate into various ceiling or wall-mounted DAS infrastructures.
