Looking for a high performance antenna in 50 MHz?

Discover our design of 4 elements BIG SIGNAL 4BS-6, one of the best options in the market related to performance / price ratio. This antenna will more than meet your expectations in the 50 MHz band, because talking about 4 Quad elements is talking about an antenna of very high performance.

Main characteristics compared to other beam antennas:

· Elements of full wavelength, reaching the maximum gain and performance.
· Attenuation of the QRM, improving the reception of weak signals in urban environments
· Extraordinary rejection/lateral, providing high directivity and reducing noise in the rejection directions
· Very low radiation angle even at low height, essential for the DX
· Very robust construction with high quality materials, with a super light weight

In times where unfortunately the QRM in cities is increasing, a closed antenna is the ultimate solution to improve the reception of weak signals in DX.

¡Make the difference, put a BIG SIGNAL on the air!

    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.
