At BIG SIGNAL we have the latest generation in the design and development of Cubical Quad antennas for the 27 MHz / 11 m band.

Why choose the BIG SIGNAL 4BS-11 antenna versus a traditional Yagi?

· Full wavelength antenna in 11 meters, reaching maximum performance and efficiency.
· More gain in less boom length than a traditional Yagi of the same size.
· Very low noise: Being a Quad antenna, it will allow you to attenuate the QRN and urban noise improving the reception of weak signals in the band.
· Very low radiation angle even when installed at a low height. This allows us to jump less to the DX, which results in a stronger signal to the other side. For this reason it is known that cubical quad antennas are the first to open and the last to close the propagation...
· High selectivity. Excellent suppression of side and rear lobes, further reducing unwanted noise in reject directions.
· Heavy-Duty construction with for extreme durability.

Being in the TOP of the BIG GUN stations in the 27 MHz band means being the owner of our BIG SIGNAL 4BS-11 antenna model. Discover the magic of Cubical Quad antennas and live a new experience in the DX in 27 MHz like never before!

    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 .

    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.

    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.
