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?

· 5 full wavelength bands, achieving maximum performance and efficiency.
· Very low noise: Being a closed antenna and horizontally polarized, it will allow you to attenuate the QRN and urban noise, improving the reception quality of weak signals in DX in the band.
· Very low radiation angle even when 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 the propagation.
· Incredible bandwidth: SWR below 1.5:1 in the 5 working bands, forget about the use of the tunner. 
· Only 5 meters in total width, ideal for installations with limited space.
· Possibility of adding a Reflector element in the future to convert the antenna into the 2BS-5B model.
· Super robust construction for extreme durability.
· Easy installation: You can install on a braced mast, it does not require any adjustment once installed.

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.

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

    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.
