Big Signal - 4BS-11 4 Element 27 MHz Cubical Quad

BIG SIGNAL 4 BS 11 Meter Cubical Quad Antenna

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 BIG SIGNAL 4BS-11 antenna versus a traditional Yagi?

· Full wavelength antenna in 11 meters, reaching 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 urban noise improving the reception of weak signals in the band.
· Very low radiation angle even when installed at a low height. This allows us to jump less to the DX, which results in a stronger signal to the other side. For this reason it is known that cubical quad antennas are the first to open and the last to close the propagation...
· High selectivity. Excellent suppression of side and rear lobes, further reducing unwanted noise in reject directions.
· Heavy-Duty construction with for extreme durability.

Being in the TOP of the most powerful stations in the 27 MHz band means being the owner of our BIG SIGNAL 4BS-11 antenna. Discover the magic of Cubical Quad antennas and live a new experience in the DX in 27 MHz like never before...
