At BIG SIGNAL we have the latest generation in the design and development of Cubical Quad antennas for the 70 MHz / 4 m band.
Why choose the 4BS-4 antenna versus a traditional Yagui?
· Full wavelength antenna in 4 meters, achieving maximum performance and efficiency. · More gain in less boom length than a traditional Yagi antenna. · Noise reduction: Being a closed antenna, it will allow you to attenuate the QRM 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 robust construction with high quality materials for extreme durability.
