Frequently Asked Questions
- Q1: What is the primary benefit of the ±45° polarization in this antenna?
- A: ±45° (Slant) polarization is highly effective for MIMO (Multiple-Input Multiple-Output) systems. It provides better de-correlation between the two signal paths, which significantly improves data speeds and link reliability in multi-path indoor environments.
- Q2: How does the 9dBi gain impact signal coverage?
- A: A 9dBi high gain allows the antenna to concentrate the RF energy into a focused directional beam. This extends the signal reach further than lower-gain omnidirectional antennas, making it ideal for covering long hallways, large open offices, or warehouse aisles.
- Q3: Is 25dB inter-port isolation sufficient for performance?
- A: Yes. An isolation of ＞25dB ensures that the signal from one port does not interfere with the other. This is crucial for maintaining signal integrity in dual-port systems, preventing noise and ensuring clear communication.
- Q4: What specific networks does the 790-870MHz band support?
- A: This frequency range is widely used for LTE Band 20 (800MHz) and other sub-1GHz cellular bands. These lower frequencies offer superior building penetration and wider coverage area compared to high-frequency bands like 2100MHz or 2600MHz.
- Q5: Can this antenna be used for outdoor installations?
- A: While primarily designed for in-building solutions (IBS), its rugged panel construction and N-Female connector can support outdoor use if installed with appropriate weatherproofing. For permanent outdoor use, please verify the specific IP rating required for your environment.
