Looking for maximum performance in a dual-band V-UHF directional antenna?

Discover our model: BIG SIGNAL 10BS-270. This design begins to be an antenna for radio amateurs serious to work long-distance terrestrial communications or for use in satellite communications. Length of the boom is just 1.2 meters making it ideal for small spaces but guaranteeing an incredible performance with 4 elements active in VHF and 6 elements Quad in the UHF band.

Why choose a Cubical Quad antenna 10BS-270 versus a traditional Yagi?

· Full wavelength antenna in 2 meters and 70 centimeters, reaching maximum performance and efficiency.
· More gain and performance in less boom length than a traditional yagi of the same size.
· Very low noise. Being a closed Quad antenna, it will allow you to reduce the QRN and urban noise, improving the reception quality of weak signals in the bands.
· Less influence to cross polarization. This translates into less QSB, fading or loss of signal when receiving signals in different polarization, ideal for communications via satellite.

· Very high selectivity. Excellent suppression of side and rear lobes, further reducing unwanted noise in reject directions.
· Quick and easy installation: pre-assembled elements, assembly without tools.

The best directional antenna option for 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.

    Compre para la estación fija la BIG SIGNAL 10BS-270 (6 elts UHF y 4 elts VHF) y funciona mejor que mis Yagis de 9 elts y 10 elts cruzados en VHF y UHF que además son monobanda.
    Tan pronto como hace buen tiempo, la comparo con los 11 elts horizontalmente...

    La antena es de una calidad y eficiencia excelente. La puedes usar con garantía de éxito en FM, SSB y para satélites. Para satélites tienes la opción de ponerle la placa de elevación fija. Es una buena antena tanto para estación fija como portable. Estoy muy contento con ella la verdad.

    Muy buena antena, desde que empecé con las pruebas para ver qué antena ponía en mi QTH (una zona muy alejada, en el noroeste de la Región de MURCIA), ya que no esperaba buen resultado de ninguna, me quedé sorprendido con el rendimiento que me ofrecía tanto en Vhf como en Uhf. Llegando a zonas como Cartagena en directo y sin tener la antena dirección allí. Muy contento con el resultado, sin duda si tenéis mala ubicación contactar con BigSignal y os encontrará una solución.
