At BIG SIGNAL we have the latest generation in the design and development of cubic antennas for the 14 MHz / 20 m band.

Why choose a BIG SIGNAL 2BS-11 Quad antenna versus a traditional Yagui?

· Full wavelength elements: reaching maximum performance and efficiency.
· Very low noise: being a closed quad antenna with horizontal polarization, it will allow you to attenuate QRN and urban noise, improving the reception quality of weak signals in the band.
· More gain in less boom length than a traditional Yagi of the same size.
· Very low radiation angle even installed at a low height: this allows us to make fewer jumps until we reach the DX, which results 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 propagation.
· High selectivity: Extraordinary side and back lobe suppression, further reducing unwanted noise in the rejection directions.
· Less crossover or polarization influence: This translates into less QSB and signal stability when receiving DX stations.
· Just over 2 meters of turning radius. Ideal in small spaces, no antenna is capable of offering this performance and turning in such a small space.
· Super robust construction for extreme durability, forget about maintenance.
· Very light weight compared to aluminum Yagis with similar characteristics.
· Simple assembly and Plug&Play: it does not require any adjustment once installed.

Because a Quad antenna is the best directional antenna for DX due to its performance and benefits. In addition, in times where the noise in cities is increasingly high, a cubical quad antenna is the definitive solution for the practice of DX with the maximum performance guaranteed.

    Que decir de la 2BS-11 pues la monte hace un año después de tener un Yagui de 4 elementos y los resultados de la 2BS-11 son brutales, me dejó sorprendido a solo 6 metros de altura no pare de contactar divisiones y una recepción muy muy buena y poco ruido incluso poniendo lineal a 800 W. sin acoplador y la antena seguía con 1.2 de SWR me dejaba sin palabras. Muy contento al solo tener ese pequeño boom y los resultados que me dio.

    Had this antenna for a few weeks now and its only been over the last few days ive found out how good it is with the skip now staring to show in the UK. Ive had many QSO so far on this antenna and all reports are fantastic so if you have limited space and you want to be a top DX station i cannot recommend this antenna enough its also very light and very easy to put at a good height Iam over the moon with this antenna all i can say is many thanks to BIG SIGNAL ANTENNAS FOR A BEAUTIFUL ANTENNA 73S

    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
