· Full-Wavelength Elements: Our antenna makes the most of every centimeter of the wavelength, achieving unmatched performance and efficiency.
· Superior Gain in a Compact Space: Despite its compact size, our antenna outperforms traditional Yagis of similar dimensions in gain.
· Noise Elimination, Enhanced Reception: Thanks to its closed design, this antenna minimizes QRN and urban noise, allowing you to receive weak DX signals with stunning clarity.
· Low Radiation Angle: Even when installed at a low height, this antenna maintains a low radiation angle, resulting in stronger signals and extended DX communication reach.
· DX Signal Stability: Less influence from polarization changes translates to less QSB and increased stability when receiving DX stations.

    I've had that 4BS-11 for over a year now, and it never ceases to amaze me ? it's like a missile of an antenna.

    Ya tengo la antena instalada y a pleno funcionamiento. Ha sido una instalación compleja, mastil, rotor, arriestrarla, el equipo de antenistas "Vesatel Servicios Integrales" y el operador de la Grua "Gruas Moreno", 10 puntos, sin ellos no hubiera sido posible, la antena es muy grande y su montaje es complejo.
    Los resultados son ESPECTACULARES, DX con facilidad con poca propagación, cuando hago el cambio a la vertical, obtengo 4/5 puntos de diferencia de señal. Es un "Cañon", estoy feliz por la inversión , la instalación y el performance que esta demostrando la Big Signal 4DS-11. DX con dos estaciones chilenas 17 horas UCT mas de 35 minutos de QSO, con señal sostenida en las dos direcciones. Comentario final: Big Signal 4DS-11 es una antena de alto rendimiento. Gracias Big Signal por fabricar algo tan espectacular.

    I already have the antenna mounted on the tower and began to test it with almost no propagation. I have made QSO with New Caledonia, New Zealand, Australia, Thailand, Qatar, Brazil with signals from 4 to 9+ and radio 4-5 with only 50 Watts!!!

    The antenna keeps all the stated promises, I keep hoping for better propagation.

    Well done BIG SIGNAL!

    After many months now of Purchasing the 4 Element Big Signal 4BS-11 Cubical Quad I have now finally managed to get the chance to install this great antenna.

    At times I am the only one local in Glasgow, Scotland hearing and working stations on the 11m band. Thanks Big Signal, Gary 108AT101

    De tener una verdadera bomba para el DX que es la 2 elementos y pensar que mejor no podía ser, he pasado a alucinar pero esta vez con la 4 elementos. Nunca pensé que esto pudiera suceder. En Valencia soy el primero en escuchar la propagación . Señales de +20,+30 en toda Europa con 50W. No se que más decir, excepto que estoy contentísimo . Gracias BIG-SIGNAL .

    The Quad is working amazing and sometimes i am the only one hearing stations on the band.

    Hallo Big Signals,
    I will give you now after near 9 month a short answer and back up about the 4 Element Cubical Quad 4BS-11. Before I changed my system I have a 4 ele Yagi special build for my opinion and dates....it works very nice....but now I must say the Quad works amazing super top.... Big difference in working wise to a yagi....and I must learn a little time to use the Quad perfect. A lot more Gain and more RX makes this antenna to a super gun.

  11. Nino (34AT040)10 May, 2018 - 11:50

    Transmito para Europa con tan solo picos de 3 W. y pongo señales de 8 y cuando le digo a los corresponsales que estoy tan solo con 3 W. hay una exclamación ohhhh good. Al día siguiente de montar la antena trabajé la estación 271DA/0 en el Pacifico Central y mi colega que esta a 600 metros de mi casa no la escuchaba y yo la escuchaba 5/3 y eso que el tiene 11 metros de mástil y una Yagi de 4 elementos. Esta antena es una aspiradora de señales y un misil en transmisión.
