In BIG SIGNAL we have the famous multi-band Cubical Quad antenna with 2 elements and 3 bands. ¡The real queen of the DX!

But this is a model that currently breaks all the schemes in this type of antennas, from the optimization of electrical design with state-of-the-art software to the mechanical part, innovating and using the latest advances in materials guaranteeing extreme durability.

Why choose the 2BS-3B antenna versus a multiband Yagi antenna?

· 3 bands of full wavelength, reaching maximum efficiency in TX / RX.
· Very low noise because it's a closed antenna, which will allow you to attenuate the QRM and improve the reception of weak signals in DX.
· Very low radiation angle even installed at low height, essential for the DX.
· Extraordinary lateral rejection and front / back, providing high directivity and reducing noise in the rejection directions.
· Comparable performance as multiband Yagis of 3-4 el. full-size. Much bigger.
· Just over 4 meters of turning radius, ideal for installations with limited space.
· Super heavy-duty construction for extreme durability, forget about maintenance.
· Super light weight compared to aluminum Yagis with similar characteristics.

The best directional antenna option for the DX in urban environments, in times when noise in cities is increasingly high, a closed antenna is the definitive solution to improve the reception of weak signals in DX.

    Hola a todos, quiero poner mi granito de arena y comentar técnicamente sobre esta antena, al que soy un usuario de ella.
    Opté por este formato de antena porque quería sacarle partido a mi sencilla instalación respecto a una yagi tribanda que tenía (hygain Explorer 14) con 3 elementos, zona urbana y 8m sobre el tejado. Tenía qrm mínimo de S8,5/9 , ancho de banda corto y eso de llegar bien después del charco, solo con estaciones potente, y con señales inferiores de 9........ Me decidí por este formato de antena y me cambio la radio por completo, qrm bajo, como muncho a S6, tengo menos qsb en TX, paso el charco sin problema tanto para N/Sudamérica, hago pileup, backscatter, mínimo espacio, fácil montaje, ect......
    Para sacarle más partido, Juan Pedro, me la diseño con alimentación independiente para cada banda.
    Para concluir, quiero decir que si queréis una antena de alto rendimiento que ocupe poco espacio, esta es la antena!
    Gracias JP, por tu dedicación y apostar por antenas eficiente y bien hechas! 73.....
