BIG SIGNAL CQ-446
High-Performance Compact Omnidirectional Antenna for 446 MHz
The BIG SIGNAL CQ-446 is part of our CQ series of monoband omnidirectional antennas and has been specifically designed to deliver high performance on 446 MHz while taking up as little space as possible.
Its closed full-wave loop design provides an especially interesting alternative to conventional vertical antennas, combining 360° omnidirectional coverage, excellent signal-to-noise performance, and an extremely compact footprint.
Band: 446 MHz
Type: Full-wave monoband closed-loop antenna
Radiation Pattern: Omnidirectional
Polarization: Vertical
Overall Height: Only 25 cm / 9.84 in
Recommended Use: PMR446 communications / base stations / space-restricted installations
Key Advantage: Outstanding performance-to-size ratio
What Makes the CQ-446 Different?
• 360° omnidirectional coverage
Designed to provide coverage in all directions around the station without having to point the antenna toward a specific direction, making it ideal for general communications on 446 MHz.
• Full-wave loop element
Unlike many conventional vertical antennas, the CQ-446 uses a closed full-wave element, designed to provide high electrical efficiency within an extremely compact footprint.
• Clean reception and excellent signal-to-noise performance
Its closed-loop geometry can help reduce pickup from certain types of electrical noise, improving the intelligibility of weak signals in environments affected by interference.
• Only 25 cm / 9.84 in tall
One of its greatest advantages is its exceptional size-to-performance ratio. At just 25 cm / 9.84 in in overall height, it can be installed where a conventional vertical antenna would be too large or visually intrusive.
• Ideal for discreet installations
Its compact dimensions make it especially suitable for balconies, terraces, rooftops, compact masts, and other space-restricted locations.
• Simple installation
Designed for quick setup without complex adjustments, providing a dedicated 446 MHz antenna solution in a remarkably small footprint.
A Different Alternative to the Traditional Vertical
The CQ-446 is designed for operators who need omnidirectional coverage but want something different from a traditional vertical antenna. Its full-wave element, closed-loop geometry, and compact dimensions combine 360° coverage with a much smaller and more discreet installation.

Très bonne antenne pour ma station PMR 446. SWR 1.0. De magnifiques QSO. CRT 7M 45 Watts. Merci au vendeur pour la qualité des matériaux et de l?emballage lors de l?envoi. Je pense prendre la même pour le 2 M. 73?s
En comparación con mi stack de 2 x 3 elementos Yagi, la CQ-446 solo saca 1 punto menos de señal, muy bueno en vista de la polarización omnidireccional para el CQ-446 y la directiva para el 2x3. Muy satisfecho con mi compra, la recomiendo buen diseño, fácil de instalar con muy buen ROE en toda la parte PMR 446 a 446.200 MHz ROE de 1.1 a 1.2 con 45 Watt... Felicidades a BIG SIGNAL.
