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.

    here my first impression from this antenne.
    the gain on 70 cm is not what i expected on my vertical is it beter (xn300) but i must tell i use the rg213 coax and on the vertical a better coax. wil change in future the coax.
    on 2 meter the antenne is real good and made my first contact on 2 meter in south france never heard any dx on 2 meter with vertical.
    will continue !!!!

    Quisiera daros algunos comentarios directos sobre la BIG SIGNAL 10BS-270. Estaba funcionando el satélite AO-27 hoy, y nunca había escuchado antes señales tan fuertes y la primera estación a la que llamé respondió. Anteriormente estaba usando 2 antenas ARROW configuradas para RHCP y pude escuchar muchos satélites, pero nunca tan fuertes como con esta antena y también a 5 grados sobre el horizonte.

    Hey I just wanted to give you some direct on the air feedback about the BIG SIGNAL 10BS-270. Was working satellite AO-27 today and I have never heard signals that strong before and the first station I called responded. I was previously using 2 arrow antennas set-up for RHCP and I was able to hear many of the sats, but never that strong and heard them sooner also at 5 degrees above horizon.

    Encantado con esta pequeña antena, es increíble los contactos realizados en directo sin propagación troposférica que pudiese ayudar. Desde JN01um he trabajado Valladolid, Murcia, Burdeos, Mallorca... entre otros, aparte de su buen funcionamiento para satélites, todos los contactos, siempre realizados desde el QTH en FT-8. Estos días coinciden la lluvia de estrellas Líridas y he realizado 2 contactos rozando los 2.000 Km en Meteo-Scatter (MSK144) y no estamos en la jornada plena de lluvias meteóricas. Sin duda un acierto su compra.

    Hola, soy EB4GDB, compre esta antena vuestra y os mando unas fotos, estoy encantado con ella, para satélites y para concursos. Muchas gracias.

    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.
