Are you looking for a high performance bi-directional antenna? Discover the BIG SIGNAL 1BS-5B, this single element Quad design covers up to 5 bands in HF from 10 to 20 meters. An incredible high-performance bi-directional antenna option to get started on the DX in HF without the need for a complex setup or a large investment. The best market option in terms of performance / price!

Why choose the 1BS-5B antenna versus a Yagi or Dipole antenna?

· 5 bands of full wavelength, reaching maximum efficiency in TX / RX.
· Very low noise because its a closed antenna, which allows it to improve the reception of weak DX signals masked by the QRM.
· Very low radiation angle even at low height, essential for working DX.
· Reduced turning radius, ideal for limited spaces.
· Comparable performance with a full-size 2 element Yagi.
· Heavy-Duty construction for extreme durability.

In times when unfortunately the noise in the cities is increasingly high, a closed antenna and horizontal polarization is the definitive solution to improve the reception of weak DX signals masked by the QRM.

    Es una maravilla de antena. En el entorno ruidoso que tengo en la ciudad, antes con la vertical, el ruido no bajaba de 7-8. Ahora con DX-Quad, en función de la orientación, día, hora y banda, el ruido ha bajado entre 2-5 puntos. Respecto a la ROE, olvidaros del acoplador, siempre entre 1 y 1,5. En definitiva, una magnífica antena para los vivimos en la ciudad.
