Discover the BIG SIGNAL 1BS-5B antenna, this single element Quad design covers up to 5 bands in HF from 10 to 20 meters, the best high performance bi-directional antenna option to get started in DX in HF with a simple configuration and not a big investment.

Why choose the BIG SIGNAL 1BS-5B antenna over a Yagi or multi-band Dipole antenna?

· Full wavelength antenna achieving maximum performance and efficiency.
· Reduction of the QRM because it is a closed antenna, which will allow you to improve the reception of weak DX signals in urban environments.
· Very low radiation angle, essential for working the DX.
· Only 5 meters in total width, ideal for installation in tight spaces.
· Possibility of adding Reflector element in the future to convert the antenna into the 2-element BIG SIGNAL 2BS-5B model.
· Easy assembly and installation on braced mast.

In times where unfortunately the noise in the cities is getting louder, a closed antenna and horizontal polarization is the definitive solution to improve the reception of DX signals.

    Estoy encantado con el rendimiento, sin ROE, sin necesidad de usar el acoplador. Menos QRM y mejor recepción que mi anterior antena. Trabajo mucho en QRP, la estrené con un contacto en fonia con tan solo 5 W. de potencia con la expedición de Gambia (C5) y me escucho alto y claro a la primera...

    Que decir de esta antena,un solo elemento y el rendimiento bestial,unas señales tremendas,me quite la COBWEB
    autoconstruida y me puse la 1BS-5B y madre mia que diferencia,ademas el QRM,casi inexistente desde luego es lo
    mejorcito en antenas de un solo elementos y 5 Bandas,ah ROE,brilla por su ausencia lo maximo 1.3 en 28 Mhz y sobre todo tambien el ancho de banda cubre con creces las espectativas de todo Radioaficionado.
    Bueno que decir del aguante al viento la tengo a 15 metros de altura se doblaba un poco si pero al ser la fibra de calidad volvia al sitio otra vez,aguantado al 100,ah y en la banda de 40 y 60 metros acoplaba con un rendimiento
    bastante aceptable,sobre todo en 60 Mtrs,materiales todo ok,este año le pedire a Juan Pedro el reflector y ha hacer DX
    os la recomiendo...

    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.
