Main Features
The LX-PA-UHF-380-450-11 is a heavy-duty infrastructure solution for critical UHF communication networks. Utilizing a ±45° dual-polarization architecture, it provides superior signal diversity and throughput in complex urban and industrial environments. With an 85° horizontal beamwidth, this antenna offers broad sector coverage, while the 38° vertical beamwidth is precision-engineered for effective ground-level signal penetration. Its massive 400W power handling and ultra-low PIM performance ensure that it can manage high-density traffic without generating self-interference. Housed in a durable 900mm UPVC radome with a DC-grounded lightning protection system, it is built to endure extreme wind loads up to 60m/s and temperatures as low as -40°C.
Application Scenarios
- TETRA & P25 Base Stations: High-performance sector antenna for police, fire, and emergency service networks.
- Critical Infrastructure Trunking: Ideal for utility grids, oil and gas refineries, and large-scale industrial site communications.
- Public Safety Signal Densification: Provides high-gain directional coverage for tunnels, transit hubs, and municipal corridors.
- Broadband UHF Data Links: Supports high-speed mission-critical data transmission with dual-stream diversity.

Product Q&A
- How does the ±45° polarization benefit UHF trunking systems?
- Dual ±45° (slant) polarization provides better signal decorrelation compared to traditional vertical/horizontal setups. This significantly improves reception in multipath environments, reducing fading and enhancing the reliability of hand-held radios and mobile terminals.
- What is the advantage of the 0-15° mechanical tilt range?
- The included JM-900RZ1 mounting kit allows for adjustable mechanical downtilt. This gives engineers the flexibility to physically angle the antenna to focus the 11dBi gain on specific high-traffic areas or to limit cell-edge interference in dense network deployments.
- Why is the 400W power rating significant for this antenna?
- Most standard panel antennas are limited to 50W or 100W. A 400W rating allows this antenna to serve as a high-power primary transmitter for wide-area UHF coverage, accommodating multiple combined carriers without the risk of thermal failure or signal distortion.
