Frequently Asked Questions
- Q1: How does the wide frequency range of 380-2700MHz benefit my network?
- A: This range covers everything from Public Safety/TETRA (380-520MHz) to the higher LTE and Sub-3GHz bands. It allows for a single coupler to be used across multiple network technologies, simplifying hardware inventory.
- Q2: What makes a -160dBc PIM rating "low"?
- A: -160dBc is an extremely low noise floor. It means the unwanted signals generated by the device's passive components are nearly undetectable, which is vital for maintaining the sensitivity and speed of 5G and high-capacity 4G networks.
- Q3: Can this 300W coupler be used outdoors?
- A: Yes, with its 300W power handling and high-quality build, it can be used in both indoor and outdoor IBS solutions. However, for direct outdoor exposure, ensure it is installed within an appropriate weatherproof enclosure if required.
- Q4: Why choose the 4.3-10 connector over an N-type?
- A: The 4.3-10 connector is specifically designed to provide superior PIM stability even under low torque. It is also more compact than traditional DIN connectors, allowing for higher density and more reliable performance in modern telecommunications hardware.
