Discover the tri-band Cubical Quad antenna BIG SIGNAL 2BS-3B at BIG SIGNAL, the perfect choice for contest stations and DX enthusiasts on the 10, 15, and 20-meter bands!

Here's why a cubical antenna and the BIG SIGNAL 2BS-3B are the ultimate choice for true DX enthusiasts:

Cutting-edge Innovation: We've pushed this design to the pinnacle of excellence, from its electrically optimized design using state-of-the-art software to its construction with the most advanced materials. This ensures extreme durability and unparalleled performance in cubical antenna design.

Unmatched Performance: Compared to a conventional multi-band Yagi, the 2-element cubical antenna offers outstanding advantages:

     ·  3 full-wavelength bands: Unlike traditional Yagis (1/2 wavelength), the elements of a cubical antenna are full-wavelength, achieving maximum performance and efficiency across all its working bands.
     ·  More gain in less space: With just 2 elements, you can achieve gains similar to 3-4 element FULL-SIZE Yagis per band.
     ·  Very low noise: As closed-loop full-wave elements, QRM and urban noise are minimized, enhancing reception quality for weak signals in the band.
     ·  Very low radiation angle: Cubical antennas stand out for their low radiation angle even at low heights, allowing us to reach DX in fewer hops, resulting in a stronger signal on the other side. Cubical antennas are known for opening and closing propagation.
     ·  High selectivity: Effectively suppresses side and rear lobes, further eliminating unwanted noise in rejection directions.
     ·  Signal stability, less QSB: Thanks to the cubical quad antenna's design, reception is less affected by polarization changes, resulting in less fading or QSB when receiving DX signals.
     ·  Incredible bandwidth: SWR below 1.5:1 on its 3 working bands, eliminating the need for a tuner.

Compact and versatile: With just over a 4-meter turning radius, it's ideal for limited spaces. Its additional capability to work on the 30, 40, 60, and 80-meter bands with a tuner and very acceptable performance offers exceptional flexibility.

Unprecedented Durability: Its robust construction ensures extreme durability with no need for maintenance. Furthermore, its lightweight compared to aluminum Yagis makes it even more impressive.

Hassle-free Installation: Assembly is simple and Plug & Play; no adjustments are needed after installation.

In a world where city noise is increasingly high, the BIG SIGNAL 2BS-3B cubical antenna is the ultimate solution for DX communications with unparalleled performance.

Choose excellence, choose BIG SIGNAL, where performance reaches its peak.
Get ready to conquer DX like never before!
