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 2BS-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. · 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. · Just over 0,8 meter of turning radius, ideal for installations with reduced space. · Very robust construction with high quality materials for extreme durability.
The best directional antenna option for the DX in urban environments, in times when QRM in cities is increasingly high, a closed antenna is the definitive solution to improve DX reception.
