At BIG SIGNAL we have the latest generation in the design and development of Cubical Quad antennas for the 50 MHz / 6 m band.

Why choose the 4BS-6 Cubical Quad antenna versus a traditional Yagui?

· Full wavelength antenna in 6 meters, achieving maximum performance and efficiency.
· More gain in less boom length than a traditional Yagi antenna. 
· Very Low noise: Being a closed antenna, it will allow you to attenuate the QRM and urban noise and improve the reception of weak signals in the band.
· Very low radiation angle even installed at low altitude: This allows us to make fewer jumps until we reach the DX, resulting in a stronger signal on the other side.
· Very high selectivity. Excellent suppression of side and rear lobes, further reducing unwanted noise in reject directions.

· Heavy-Duty construction  for extreme durability.

The best option for a 50 MHz directional antenna on urban environments, in times where noise in cities is increasingly high, a Quad antenna is the definitive solution for DX practice with the maximum guaranteed performance.

    Que gran antena, tengo una y es una maravilla. La he probado con una Yagui 6 elementos y no hay color. Ahora la tengo montada a 2 metros del suelo y la comparo con una SteppIR DB18 con el Kit de 6 metros y aquí la diferencia es mucho mas grande que con la Yagui de 6 elementos, de escuchar estaciones americanas a no escuchar nada de nada con la SteppIR. Sin lugar a dudas una muy buena antena para 6 metros. Felicidades al equipo de BIG SIGNAL.
