At BIG SIGNAL we have the latest generation in the design and development of Cubical Quad antennas for the 27 MHz / 11 m band.
Why choose the 3BS-11 antenna versus a traditional Yagui?
· Full wavelength antenna in 11 meters, achieving maximum performance and efficiency. · More gain in less boom length than a traditional Yagi of the same size. · Very low noise: Being a closed antenna, it will allow you to attenuate the QRN and improve the reception of weak signals in the band. · Very low radiation angle even installed at low heights: This allows us to make fewer jumps until we reach the DX, resulting in a stronger signal on the other side. · Less influence to the polarization crossing. This translates to less QSB or signal loss when receiving signals in Vertical or Horizontal Polarization. · High selectivity. Excellent suppression of lateral and rear lobes. · Just over 2,8 meters of turning radius, ideal for installations with reduced space. · Very robust construction 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 ultimate solution to improve the DX reception.
