The BIG SIGNAL 10BS-270 model is an innovative dual-band design antenna for the 145 and 432 MHz bands of very high performance. With 10 elements in total, 4 active in the VHF band and 4 in the UHF band, it guarantees an incredible performance in just 1,2 meters of boom.

Ideal for both terrestrial contacts (FM/SSB) and for communications via SAT (satellite).

*If this is exclusive to SAT, choose the "SAT Model" version optimized at SAT frequencies (145.8 and 435.0 MHz).

Why choose a Cubical Quad antenna versus a traditional Yagi?

· Full wavelength elements, reaching maximum performance and efficiency.
· More gain in less boom length than a traditional Yagi.
· Very low noise being a loop antenna, which will allow you to improve the reception of weak signals in urban environments.
· Less influence to the polarization crossing V - H.
· Extraordinary F/S and F/B, further reducing noise in rejection directions.
· Excellent performance when crossing mountain systems.
· Heavy Duty construction for extreme durability.

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. Welcome to the antennas without noise!

    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.
