Frequently Asked Questions
- Q1: Why does the MN-OA-827-N use dual polarization (MIMO)?
- A: By using both Vertical and Horizontal polarization, the antenna can transmit and receive multiple data streams simultaneously. This MIMO technology significantly enhances data throughput and link stability in modern 4G LTE systems compared to single-polarized antennas.
- Q2: What is the benefit of the different gain values for V and H polarization?
- A: The gain varies between 3dBi and 5dBi depending on the polarization and frequency band. This optimized gain distribution ensures balanced coverage and robust signal penetration throughout indoor spaces like offices and shopping malls.
- Q3: How do the two N-Female connectors work?
- A: Each connector is dedicated to one of the internal antenna elements. This allows the antenna to connect directly to the two antenna ports of a MIMO-capable cellular repeater or base station to enable multi-stream data transmission.
- Q4: Why is the PIM rating (≤-107 dBm) important for this ceiling antenna?
- A: Low PIM (Passive Intermodulation) is crucial for maintaining high network quality. A rating of ≤-107 dBm ensures the antenna does not introduce noise into the system, preventing dropped calls and maintaining high-speed data performance.
- Q5: Can this antenna be used for all cellular operators?
- A: Yes. Because it supports the wide frequency range of 800-2700MHz, it is compatible with all global cellular bands including 800/900MHz for 2G/3G and 1800/2100/2600MHz for 4G LTE.
