PALEGIX
The PX-UA Series Underwater Combination Antenna is a versatile, high-performance communication system available in multiple configurations, including underwater fixed and collapsible/foldable designs. Engineered for seamless integration with subsea mobile platforms (AUVs, ROVs, USVs, and underwater gliders), the PX-UA series offers exceptional transmission capability, extended range, and superior anti-interference performance—ensuring reliable positioning, telemetry, and data links under complex ocean conditions.
Key Advantages & Features
-
All-in-One Multi-Frequency Integration
Combines dual-band Wi-Fi, full-band 4G LTE, UHF Radio, Iridium satellite, and GPS positioning into a compact footprint to simplify vehicle integration.
-
Flexible Structural Designs (Fixed & Collapsible)
Offers 90° foldable/collapsible external antennas and compact internal PCB configurations to suit diverse hydrodynamic and mechanical mounting requirements.
-
High Gain & Superior Anti-Interference
Delivers high antenna gain (up to 18 dBi) and low VSWR (≤1.5), optimizing link budget and ensuring stable long-distance data transmission in harsh marine environments.
