The Pro-Grade 680-930MHz Omni-Directional Antenna is engineered for demanding Unmanned Aerial Systems (UAS) and ground applications where consistent, wide-area coverage and rugged reliability are non-negotiable. Operating across a critical frequency range for long-range communication, this 4dBi gain antenna provides a robust and stable link for command, control, and telemetry data, ensuring mission success even in challenging environmental conditions.
Key Features and Technical Specifications
This antenna is designed to maximize operational range and link stability while maintaining a compact, durable form factor suitable for airborne and ground installations.
Optimized Frequency Band for Long-Range
The operational frequency range of 680 to 930 MHz is strategically chosen for its excellent propagation characteristics, offering superior penetration through foliage, buildings, and non-line-of-sight (NLOS) environments compared to higher-frequency bands. This makes it ideal for extending communication range and maintaining connectivity in complex urban or topographical settings.
True Omni-Directional Coverage
Featuring an omnidirectional radiation pattern, the antenna provides full 360-degree azimuthal coverage, eliminating the need for complex, power-intensive antenna tracking systems. This is crucial for mobile platforms like UAVs, UGVs (Unmanned Ground Vehicles), and tactical ground stations, ensuring reliable communication regardless of the platform’s orientation or movement.
High-Efficiency 4dBi Gain
The precisely tuned 4dBi gain offers an optimal balance between coverage range and pattern width. This gain focuses the RF energy efficiently toward the horizon to increase range without significantly narrowing the vertical beamwidth, thereby accommodating typical pitch, roll, and altitude changes of an airborne platform.
Ultra-Rugged IP67 Waterproof Rating
Constructed with a robust, UV-resistant radome and sealed fittings, the antenna carries an IP67 rating. This certification guarantees complete protection against dust ingress and the effects of temporary immersion in water (up to 1 meter for 30 minutes), making it fully suitable for all-weather operation, including heavy rain, snow, and humid conditions.
Lightweight and Compact Design
Built to meet the stringent payload and aerodynamic requirements of UAS, the antenna features a low-profile, lightweight design. This minimizes airframe drag and rotational inertia, leading to improved flight performance, longer battery life, and greater payload capacity for mission-critical equipment.

Versatile Application Scenarios (Use Cases)
The wideband operation and robust construction of the 680-930MHz omni-directional antenna make it a versatile asset across a broad spectrum of professional and industrial applications.
Unmanned Aerial Vehicles (UAVs) / Drones
Primary Application: Onboard data-link and telemetry communication. The antenna provides the main communication link for large-scale, fixed-wing, and multi-rotor drones. It maintains a reliable connection for high-bandwidth video downlinks, flight control data, and telemetry over extended flight paths. Its omni-directional pattern ensures that rapid changes in flight heading or altitude do not result in link loss. The rugged waterproofing is essential for atmospheric surveying, maritime operations, and deployments in adverse weather.
Ground Control Stations (GCS) and Mobile Command Centers
Ground-Side Resilience: Essential for mobile or rapidly deployable ground stations. When used on the ground control side, the omni-directional pattern allows operators to communicate with the airborne platform without precise aiming, facilitating quick setup and tear-down for tactical operations. The 4dBi gain, when paired with a directional antenna on the UAV for long-range missions, significantly enhances the overall link budget and range.
Public Safety and Emergency Response
Reliable Connectivity in Critical Moments: Supporting search-and-rescue (SAR) and disaster relief efforts. In situations where infrastructure is compromised or non-existent, this antenna ensures communication continuity. Its ability to perform well in NLOS conditions—such as around buildings, inside valleys, or through dense tree cover—is vital for first responders relying on drone-based situational awareness and coordination.
Wireless Telemetry and SCADA Systems
Industrial Monitoring: Long-range, low-data-rate industrial sensor networks. Beyond typical drone use, the 680-930MHz band is often used for long-distance, low-power telemetry links for Supervisory Control and Data Acquisition (SCADA) systems, especially in utility monitoring (pipelines, power grids) or environmental sensing. The rugged IP67 design allows for permanent outdoor installation in harsh, remote locations.
Design and Integration Benefits
Simplified Installation and Maintenance
The compact form factor and standard mounting options simplify integration onto various platforms, reducing the time and complexity of field deployment. The low-maintenance, sealed design ensures long operational lifespan with minimal risk of environmental degradation or mechanical failure.
Enhanced System Agility
The omni-directional pattern is a force multiplier for mobile systems, providing inherent spatial diversity. This eliminates manual alignment and allows the host platform (UAV or UGV) to operate at maximum maneuverability without communication constraints, increasing the efficiency and agility of the entire wireless system.
Commitment to Quality and Performance
Every unit undergoes rigorous testing for pattern fidelity, VSWR, and waterproofing conformance to ensure consistent, high-grade performance meeting the demands of professional UAS and industrial communication standards.
