BIG SIGNAL 2BS-11
The Directional Cubical Quad That Takes 11-Meter DX to the Next Level
The BIG SIGNAL 2BS-11 is a 2-element full-wave directional Cubical Quad, specifically designed for operators looking to get maximum performance from the 27 MHz / 11-meter band.
Its design combines gain, directivity, and an excellent signal-to-noise ratio in a relatively compact configuration, making it an outstanding choice for operators ready to move from an omnidirectional or wire antenna to high-performance directional DX.
Band: 27 MHz / 11 meters
Configuration: 2-element Cubical Quad
Elements: Full-wave closed loops
Type: Single-band directional antenna
Polarization: Horizontal or Vertical
Recommended Use: DX / Long-Distance Communications / Weak-Signal Operation

What Makes the 2BS-11 Different?
• Two Full-Wave Quad Elements
The 2BS-11 uses two full-wave closed loops — a driven element and reflector — specifically optimized for 27 MHz. This configuration takes advantage of the unique electrical and radiation characteristics of the Cubical Quad design.

• Gain and Directivity for Serious DX
Unlike an omnidirectional antenna, the 2BS-11 concentrates RF energy toward the selected direction, providing greater effective gain and improved capability for working weak DX signals.

• High Performance with Only 2 Elements
One of the major advantages of the Quad geometry is its excellent gain-to-size and gain-to-boom-length ratio, delivering impressive directional performance without requiring a large multi-element structure.

• Excellent Signal-to-Noise Ratio
The combination of closed-loop elements, directivity, and off-axis rejection can help reduce the pickup of certain types of interference, making it easier to copy weak signals sitting just above the noise floor.

• Strong Front-to-Back Rejection
Its directional radiation pattern concentrates reception toward the desired station while attenuating signals arriving from the rear, an especially useful advantage when the band is crowded.

• Wide Operating Bandwidth
The 2BS-11 is optimized to maintain a low SWR throughout its operating range, allowing convenient operation across 27 MHz without constant retuning or adjustment.

When Hearing Better Is Just as Important as Reaching Farther
DX is not only about putting out a strong signal. The ability to separate a weak station from noise and signals arriving from unwanted directions can make the difference between hearing the DX and missing it completely. This is where the directivity of the 2BS-11 becomes one of its greatest advantages.
Why Choose a Cubical Quad Over a Yagi?
Yagis and Cubical Quads represent two different approaches to directional antenna design. While a conventional Yagi typically uses open elements approximately one-half wavelength long, the 2BS-11 uses full-wave closed-loop elements.
With only two elements, the Quad geometry provides an especially attractive combination of gain, efficiency, directivity, and signal-to-noise performance while maintaining a relatively compact boom length.

Some Antennas Put a Signal on the Air. Others Let You Hunt for It.
The BIG SIGNAL 2BS-11 is designed for operators ready to take the next step on 11 meters. Not only because of its gain, but because of its ability to focus your signal, reject unwanted directions, and pull out DX that may remain buried in the noise with an omnidirectional antenna. When conditions get tough, directivity makes the difference.
BIG SIGNAL 2BS-11 – Less Noise. More Signal. More DX.

Muy contento de la 2BS11, la mejor antena que e tenido, muy ligera y para el poco espacio que tengo, me va de maravilla, felicitaciones por el trabajo que haceis, un saludo desde Carcaixent Valencia.
Exelente Antena la Recomiendo para Operadores que tengan poco espacio en su Qth Super Comoda !!ya por fin ensamblada y arriba en el mastil a casi 30? de altura !!Unos cambios de recepción Sorprendentes y ni comentar de los Reportes de Señal!! Wow Magníficos!! Exelente Trabajo Big Signal Fuerte Abrazo !!
Superb service from Big Signal. Previous antenna was a Moxon so I was not sure it would be a big improvement but I needed have worried. Quad is low noise but superb performance,definitely hearing stations I wouldn?t have otherwise. With the discount you get as a non EU member it?s a great deal. Arrives very quickly and a lot of care goes into the packing. Very easy to assemble even for those without practical experience.Thank you guys!!
buen dia.la antenna bignal 2B11que compre este anono tienne todas sus promesas.Antes tenia la moonraker 4 y comparar es muy dificil .Lafabrication de la big signal(como fixar el vidrio sobre el aluminio me parece muy amadora)Sin alguna ayuda contactos dificiles .SI usted pued ameliorar lasfictiationes gracias UN saludo cordial GREgorio
Súper contento con esta antena
La recomiendo para el DX
Buenísimo trabajo Big Signal
Que decir de la 2BS-11 pues la monte hace un año después de tener un Yagui de 4 elementos y los resultados de la 2BS-11 son brutales, me dejó sorprendido a solo 6 metros de altura no pare de contactar divisiones y una recepción muy muy buena y poco ruido incluso poniendo lineal a 800 W. sin acoplador y la antena seguía con 1.2 de SWR me dejaba sin palabras. Muy contento al solo tener ese pequeño boom y los resultados que me dio.
Hi from Gus in Austria??
My new antenna from Big Signal works great.
I will buy a bigger one in the near future.
Thank you Big Signal Antennas!!!

Hello from Greece , i use this 2 elem quad for 11&10m bands, excellent antenna nice gain .
Had this antenna for a few weeks now and its only been over the last few days ive found out how good it is with the skip now staring to show in the UK. Ive had many QSO so far on this antenna and all reports are fantastic so if you have limited space and you want to be a top DX station i cannot recommend this antenna enough its also very light and very easy to put at a good height Iam over the moon with this antenna all i can say is many thanks to BIG SIGNAL ANTENNAS FOR A BEAUTIFUL ANTENNA 73S
This antenna is TOP !!
I?am very happy with this antenna.
It?s not so big und I have good DX all over the world ? with minimum of power.
Very good antenna with low weight and good results. Need only a small rotor for this antenna. So at all , low costs
Llevo más de 2.700 contactos en todo el mundo en 2 años desde Indonesia, Australia, USA, Islas Tonga y otros tantos. No recuerdo haber disfrutado tanto en mis 30 años de radio. Mi reconocimiento y agradecimiento por vuestro trabajo.
