BIG SIGNAL 4BS-6
Serious power for the magic band – 50 MHz
Get ready to unlock the true potential of 6-meter DXing with the BIG SIGNAL 4BS-6—a high-performance cubical quad antenna engineered to take your station to the next level.
On a band where every decibel matters, this antenna gives you the edge to reach farther, hear clearer, and fight noise like never before.
Why choose the BIG SIGNAL 4BS-6 for 6 meters?
• High-gain 4-element full-wave design
With four full-wavelength elements, precision-optimized using advanced simulation software, this antenna delivers outstanding gain and a focused radiation pattern, ideal for serious DXers.
• True full-wave performance
Unlike typical half-wave Yagis, the 4BS-6 uses full-wavelength elements to achieve maximum efficiency in the 6-meter band.
• More gain in less space
Thanks to its closed-loop architecture, it outperforms many larger Yagis—giving you more power without the need for a massive boom.
• Ultra-quiet reception
Its full-wave closed-loop design drastically reduces QRN and urban noise, allowing you to hear weak signals with impressive clarity.
• Low takeoff angle
Even at low installation heights, it maintains an ideal low-angle radiation pattern—perfect for long-distance DX contacts.
• High directivity with excellent lobe suppression
Superior front-to-back and front-to-side ratios help reduce interference from unwanted directions and focus your signal right where it counts.
• Built tough for real-world conditions
Made from high-quality materials, this antenna is built to last—engineered for extreme durability and maintenance-free performance.
The ultimate solution for high-noise urban environments
If you're operating in a noisy location, the BIG SIGNAL 4BS-6 is your best ally. Its closed-loop design dramatically improves signal clarity, allowing you to experience real DXing—even from urban rooftops or small towers.

Que gran antena, tengo una y es una maravilla. La he probado con una Yagui 6 elementos y no hay color. Ahora la tengo montada a 2 metros del suelo y la comparo con una SteppIR DB18 con el Kit de 6 metros y aquí la diferencia es mucho mas grande que con la Yagui de 6 elementos, de escuchar estaciones americanas a no escuchar nada de nada con la SteppIR. Sin lugar a dudas una muy buena antena para 6 metros. Felicidades al equipo de BIG SIGNAL.
Fantástica antena y resisssssstente al aire vale la pena
