Indoor 380-4000MHz Slim Omni Ceiling Antenna Low PIM

, , , ,

The LX-340-24-NF-153 is an ultra-thin wideband omni-directional ceiling antenna designed for premium indoor wireless coverage. Supporting an expansive frequency range from 380MHz to 4000MHz, it provides a “one-antenna” solution for UHF, 4G LTE, and 5G Sub-6GHz networks. With its high-performance -153dBc Low PIM rating and discreet slim profile, it is the ideal choice for high-density DAS deployments.

  • Ultra-Wideband Coverage (380-4000MHz): A single antenna covering UHF (TETRA/Public Safety), GSM, 4G LTE, and 5G bands, simplifying multi-service indoor network design.
  • Superior Low PIM Performance: Certified at ≤-153dBc (@ 2x20W), ensuring minimal interference and maximum data throughput for modern high-speed networks.
  • Sleek, Low-Profile Design: Measuring only 19mm in thickness, this “invisible” antenna blends seamlessly into modern architectural ceilings without compromising performance.
  • High Reliability & Easy Install: Features a DC-grounded design for lightning protection and a simple nut-fixed mounting system for fast, secure installation in any ceiling type.

Main Product Introduction

The Luxun LX-340-24-NF-153 is engineered for the next generation of indoor Distributed Antenna Systems (DAS). By combining a wide frequency response with an ultra-slim aesthetic, this antenna solves the challenge of providing high-capacity cellular coverage while maintaining interior design integrity. Its 360° horizontal radiation pattern ensures consistent signal strength throughout open-plan offices, malls, and public venues.

Critical for 5G and LTE-Advanced networks, the antenna’s low Passive Intermodulation (PIM) ensures that the network operates at its peak efficiency, reducing dropped calls and enhancing user data speeds. The robust construction allows for a wide operating temperature range (-35°C to +65°C), ensuring long-term stability. Equipped with 2*N-Female connectors (or customizable options), it offers the flexibility needed for various system architectures.

Application Scenarios

  • Multi-Operator DAS: Ideal for neutral host deployments where a single antenna must support multiple carriers and frequency bands (UHF/4G/5G).
  • Public Safety Networks: Reliable 380-520MHz coverage for emergency services and TETRA systems inside buildings.
  • Commercial Real Estate: Discreet high-speed wireless for luxury hotels, shopping centers, and Grade-A corporate offices.
  • High-Density Venues: Ensuring stable connectivity in airports, stadiums, and conference centers where Low PIM is vital for network capacity.

FAQ

Q: Why is the 380MHz frequency support important?
A: Support for 380-520MHz allows this antenna to be used for Public Safety and TETRA networks, making it a versatile solution for both commercial cellular and emergency communication systems.
Q: How “slim” is the antenna really?
A: The antenna body is only 19mm thick (Ø280mm diameter). It sits much flatter against the ceiling than traditional mushroom-style antennas, making it virtually unobtrusive.
Q: What does -153dBc Low PIM mean for my network?
A: Low PIM (Passive Intermodulation) means the antenna produces significantly less internal noise. This results in cleaner signals, fewer data errors, and a better overall experience for mobile users.
Q: Is this antenna 5G compatible?
A: Yes. Its range extends up to 4000MHz, covering the critical N77 and N78 5G Sub-6GHz bands used globally.
Q: How is the antenna mounted?
A: It uses a simple through-hole mounting system secured with a nut from above the ceiling tile, providing a clean and professional “flush-mount” look.
