BiQuad antenna 10,5dbi gain 1280Mhz

Professional-Grade Biquad Antenna - 10.5 dBi High-Gain Performance

Elevate your signal reception with our precision-engineered biquad antenna, designed for both amateur radio enthusiasts and professional applications. Featuring a gain of 10.5 dBi, this antenna ensures exceptional performance and reliability across the 23cm band.

Technical Excellence

Superior Biquad Design: Our antenna utilizes the proven biquad configuration - a dual-loop driven element that delivers exceptional directivity and front-to-back ratio. This design provides optimal impedance matching and consistent radiation patterns, making it ideal for point-to-point links and targeted signal reception.

Optimized Frequency Response:

• Center Frequency: Precisely tuned for 1280 MHz with VSWR below 1.1
• Usable Bandwidth: 1200-1430 MHz (VSWR < 1.5) - covering the entire 23cm amateur band
• Bandwidth: ~230 MHz of usable spectrum for versatile applications

Key Performance Features

• High Gain of 10.5 dBi: Delivers approximately 11x power multiplication, extending your operational range significantly while maintaining clean signal quality
• Directional Radiation Pattern:
  • Focused beamwidth reduces multipath interference
  • Excellent front-to-back ratio minimizes unwanted signals
  • Ideal polarization characteristics for maximum signal transfer
• Low VSWR Performance: Exceptional impedance matching ensures maximum power transfer and protects your transmitter from reflected power
• Consistent Performance: Stable gain and pattern characteristics across the entire operating bandwidth

Build Quality & Durability

• Weather-Resistant Construction: Engineered with UV-stable materials and corrosion-resistant elements for long-term outdoor deployment
• Robust Mechanical Design: Reinforced feed point and element mounting withstands wind loads and temperature extremes (up to 70 degrees)
• Professional-Grade Components: High-quality coaxial connector (SMA available) with weatherproof sealing

Installation & Setup

• Plug-and-Play Ready: Pre-assembled design requires no tuning or adjustment in the field
• Versatile Mounting Options: Compatible with standard mast mounting hardware

Quality Assurance

Individually Tuned and Tested: Each antenna undergoes rigorous quality control:

• Network analyzer sweep verification across full bandwidth

Why Choose Our Biquad Antenna?

Unlike generic wideband antennas, our biquad is specifically optimized for the 1280 MHz band, ensuring peak performance where you need it most. The careful attention to impedance matching and element spacing results in superior gain flatness across the operating band - critical for digital modulation schemes and video transmission quality.

Package Includes:

• 1x Precision-tuned Biquad Antenna
• Mounting hardware inculded on antenna

Upgrade your RF setup today and experience the superior quality and performance that only a properly designed and individually tested biquad antenna can deliver. Whether you're pushing the limits of FPV range, establishing reliable data links, or exploring weak signal communications, our antenna provides the robust and efficient signal boost you need.

Note: Actual range and performance depend on factors including transmitter power, receiver sensitivity, environmental conditions, and line-of-sight availability.
