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.

Great antenna. Well made. Bandwidth and SWR exactly as advertised. Has been in the air nearly 12 months with no issues whatsoever. Recommended.
Amazing antenna...even when touching the ground still +10dB into Mexico!
Would definitely buy another one...maybe 4 Element next.
.already had the 2 Element which works amazing also.
Thank you Big Signal Antennas ??
