Ultra-Wide Bandwidth • Reinforced Housing • Low Drag • High Power Handling • Optimized Axial Ratio

The Omni_protector_UVB is a next-generation wideband omnidirectional antenna engineered for professional FPV, UAV, industrial and high-frequency communication systems. Built on our re-designed semi-protected cloverleaf structure, it combines exceptional RF performance, outstanding mechanical durability, and aerodynamic efficiency—without the limitations commonly found in fully enclosed antennas.

Key Features

Ultra-Wide Useful Bandwidth (5000–6000 MHz)

The antenna maintains a VSWR below 1.5 across 700mhz exceptionally broad frequency range, ensuring stable performance for both standard 5.8 GHz systems and specialized high-frequency digital or telemetry applications.
Wide, predictable bandwidth means reliable links even in demanding RF environments.
those antennas are mainly tuned for low and middle channels.

Clean Omnidirectional Pattern with Enhanced Gain

The Omni_protector_UVB delivers a balanced, well-defined omnidirectional radiation pattern with refined gain characteristics—perfect for aircraft that change orientation frequently.

Optimized Axial Ratio – Superior Circular Polarization

A high-quality axial ratio is crucial for FPV and UAV operations, and this antenna was designed with that in mind.

A low axial ratio provides:

✓ Strong suppression of multipath interference
✓ Cleaner, more consistent video feed
✓ Improved signal stability during aggressive maneuvers
✓ Better penetration and reduced breakup in reflective environments

The result is a more robust and reliable link compared to antennas with poor polarization purity.

Available Version

Currently the Omni_protector_UVB is offered exclusively in RHCP.
A LHCP variant may be released depending on demand.

Re-Engineered Cloverleaf Design – Protected, Not Over-Enclosed

This antenna is based on our custom-tuned cloverleaf geometry, integrated into a semi-enclosed housing that offers the perfect blend of strength, RF transparency and aerodynamic performance.

Advanced GF-Reinforced Housing

The enclosure is made from reinforced polymer , chosen specifically for antennas due to its unique advantages:

✓ Greatly improved impact and crush resistance
✓ High dimensional stability even at elevated temperatures
✓ Electrically neutral material – it does not interfere with RF radiation, maintaining perfect antenna characteristics

This material allows the antenna to remain rugged while delivering uncompromised RF performance.

Why Semi-Protected Instead of Fully Enclosed?

Our hybrid housing design offers several important benefits:

• Reduced aerodynamic drag – ideal for multirotors and high-speed wings
• Higher power handling – fully sealed antennas trap heat; our design dissipates it efficiently
• Lower weight – improving flight time and center-of-gravity balance
• High durability – far superior to open cloverleaf designs, ideal for repeated crashes or industrial use

Temperature Resistance

Engineered for demanding environments, the antenna maintains stable performance from –30°C to +90°C, making it suitable for winter flying, hot summer operations, and industrial-grade applications.

ProDrone Quality Assurance

Every Omni_protector_UVB antenna is manufactured with premium materials and individually calibrated:

• Precisely tuned radiating elements
• High-quality soldering and assembly
• Each antenna tested on a spectrum analyser
• QC label with simplified performance data included

Why individual testing matters?

At 5–6 GHz even a microscopic 0.1 mm geometry change shifts the resonant frequency.
By testing every single antenna we ensure:

✓ perfect tuning
✓ consistent performance
✓ no “lottery effect”
✓ optimal operation at your target frequencies
