At BIG SIGNAL we have the latest generation in the design and development of Cubical Quad antennas for the 27 MHz / 11 m band.

Why choose the 2BS-11 antenna versus a traditional Yagui?

· Full wavelength antenna in 11 meters, achieving maximum performance and efficiency.
· More gain in less boom length than a traditional Yagi of the same size.
· Very low noise: Being a closed antenna, it will allow you to attenuate the QRN and improve the reception of weak signals in the band.
· Very low radiation angle even installed at low heights. This allows us to make fewer jumps until we reach the DX, resulting in a stronger signal on the other side. For this reason it is known that Quad antennas are the first to open and the last to close the propagation...

· Less influence to the polarization crossing. This translates to less QSB or signal loss when receiving local signals in Vertical Polarization.
· High selectivity. Excellent suppression of lateral and rear lobes.
· Just over 2 meters of turning radius, ideal for installations with reduced space.
· Heavy-Duty construction for extreme durability.

Discover the magic of Cubical Quad antennas and live a new experience in the DX in HF like never before...

    This antenna is TOP !!
    I?am very happy with this antenna.
    It?s not so big und I have good DX all over the world ? with minimum of power.
    Very good antenna with low weight and good results. Need only a small rotor for this antenna. So at all , low costs
