Unmatched Signal Quality: This antenna's precision engineering results in a low Voltage Standing Wave Ratio (VSWR), typically 1.5:1 or better, ensuring that nearly all transmit power is efficiently radiated and received signal clarity is maximized. The high-quality construction minimizes signal loss across the spectrum, delivering a clean, strong signal necessary for high-throughput data and low-latency control.
Primary Use Scenarios: Where Reliability Matters
1. Long-Range UAV Telemetry and Control (BVLOS)
In missions that extend Beyond Visual Line of Sight (BVLOS), maintaining a solid command and control (C2) link is paramount. The 350-400MHz frequency is less susceptible to environmental attenuation (like foliage or terrain) than higher frequencies, making this antenna ideal for:
Mapping and Survey: Maintaining a stable link for large area coverage in agriculture, mining, or infrastructure inspection.
Search and Rescue (SAR): Ensuring continuous communication with the GCS across challenging and remote landscapes.
Pipeline and Powerline Monitoring: Reliable data relay over long, linear routes.
2. Fixed Ground Control Station (GCS) Base Stations
This antenna is perfect for establishing a high-performance ground base station. When mounted on a tripod, mast, or vehicle, it significantly increases the effective range and stability of the entire system. Its omni-directional pattern ensures the GCS can maintain contact with the UAV regardless of the aircraft's bearing, providing an essential foundation for multi-directional flight paths.
3. Critical Infrastructure Monitoring
For applications involving persistent surveillance or data collection around critical sites—such as border control, oil rigs, or large industrial complexes—the antenna provides a rugged, set-and-forget solution that resists corrosion and vibration, guaranteeing continuous operation under harsh operational cycles.
Why Choose This Fiberglass Antenna?
