BIG SIGNAL 6BS-2
6-Element Cubical Quad Antenna for DX and Weak-Signal Operation on 144 MHz
The BIG SIGNAL 6BS-2 is a 6-element directional Cubical Quad antenna specifically developed for operators looking for gain, directivity, and an excellent signal-to-noise ratio on the 144 MHz / 2-meter band.
Its architecture based on full-wave loop elements provides a highly interesting alternative to traditional Yagi antennas, especially for terrestrial DX, weak-signal operation, SSB, digital modes, and demanding VHF links.
Band: 144 MHz / 2 m
Type: Single-band directional Cubical Quad
Elements: 6 full-wave elements
Applications: DX / weak signals / SSB / digital modes
Design: High directivity and excellent signal-to-noise ratio
Assembly: Pre-assembled elements

Why Choose the BIG SIGNAL 6BS-2?
• 6 Full-Wave Loop Elements
The 6BS-2 uses full-wave closed-loop elements, one of the fundamental characteristics of the Cubical Quad design and the basis of its excellent performance on 144 MHz.

• High Gain in a Compact Design
Its six-element configuration is designed to provide high directional performance without requiring an excessively long structure, making installation easier on towers and compact rotator systems.

• Clean Reception and Excellent Signal-to-Noise Ratio
The closed-loop geometry of its elements can contribute to a better signal-to-noise ratio in the presence of certain types of electrical interference, an especially valuable advantage when working with signals close to the reception threshold.

• High Directivity and Selectivity
Its directional radiation pattern helps concentrate energy toward the desired direction while reducing signals arriving from unwanted directions, improving the ability to separate stations and work DX under demanding conditions.

• Good Performance with Polarization Variations
The Cubical Quad geometry can be less sensitive to certain changes in the polarization of received signals, helping provide more stable reception under variable propagation conditions.

An Antenna with a Place in VHF History
Used by EA8CXN in a Historic Transatlantic 144 MHz Contact
The BIG SIGNAL 6BS-2 was used by César, EA8CXN, in one of the most remarkable tropospheric contacts made on the 2-meter band, from the Canary Islands to the Caribbean. A real-world example of the potential of a well-optimized station when antenna performance, propagation, and operating conditions come together favorably.
Note: Long-distance communication results depend on multiple factors, including propagation, location, antenna height, transmit power, system losses, and installation conditions.

When IO-117 covers the United States, I usually can't hear it until it's at least 10 degrees elevation. And I usually can't hit the satellite on transmit until it's nearly 20 degrees. With the new antenna, I heard and hit the satellite at about 3 degrees elevation.
Como usuario de varios modelos, entre ellas esta antena, simplemente indicar que la calidad y rendimiento, comparado con otras del mercado con mas elementos.Atendimiento especial.
Aconsejable 100%, y mejor servicio técnico.
Una antena fabulosa!! en poco espacio tienes una gran antena, con una ganancia excepcional. Me dedico principalmente a satelites y DX, tanto en esporadica como meteorica. Excelente para todo!!
Simplemente genial. Instalarla es cosa de niños.
El primer día, con viento a favor gracias a unas buenas condiciones en las troposfera, con 50 watts me planté en JO02 (1068 kilómetros). Toda la mañana trabajando estaciones inglesas y francesas (JO01, IO91, JO10... todas a más de 900 kilómetros). El rendimiento es genial, apenas hay ruido.
Los satélites han pasado a ser un juego de niños, sin apenas fading y aprovechando un porcentaje muy elevado de cada pase.
¿Y qué decir del servicio? Un trato genial, a prueba de manazas como yo.
La única pega que le veo es que llevo todo el fin de semana sin salir del cuarto de radio buscando nuevas cuadrículas.

Trato excelente y antena espectacular.
Muy contento con la 6bs2, muy sencilla de montar, materiales de excelente calidad y una atencion al cliente de 10 por parte de Big Signal.
Una antena muy silenciosa, venia de una yagi de los mismos elementos y la diferencia es muy grande en ruido (mucho menos la cubica), la mia esta optimizada para SSB (montada en polarizacion horizontal) pero trabajo satelites sin ningun tipo de problema , con escasos 5w señales de s7/s9 en los satelites de ssb.
En este ultimo concurso contactos sin el mas minimo problema a 300/400km.
Roe totalmente plana en toda la banda, en resumen una excelente compra.
Agradecer la amabilidad que ha tenido Tino de MTF Telecomunicaciones, mostrándome tres modelos para esta banda y valorando cual se adaptaba mas a mis necesidades. Con una profesionalidad admirable.
Lo primero que destacaría de esta antena es su robustez, es una antena para colocarla sobre mástil o torre y olvidarte de ella. Te aguantara años soportando cualquier temporal.
La instalación es sencilla con un manual bien detallado, Todo el conjunto bien señalado y marcado por Bigsinal para montar y olvidarte de mas ajustes.
Instalada en el campo sobre un mástil a unos 4 o 5 metros de altura, con 10 metros de aircel 7 la roe es plana en toda la banda, a baja altura subirá un poco la roe por 145 pero nada alarmante. En este apartado de roe, la calificaría de excelente.
Esta antena nos sorprendió a todos los colegas que estuvimos en la prueba, recomendable y a tener en cuenta con buena oreja y bajo ruido.
Muy contento con el producto y la atención en tienda.
Saludos.
León.

Desde mi QTH en Lloret de Mar (Gerona) he hecho QSO con Castellón, Valencia, Alicante... buenas señales, me dicen como un QSO local. Con Barcelona hago rueda cada día y cuando no hay propagación con la vertical no copio nada y con la cúbica si copio y me copian. ¡Se quedan asombrados! En principio creo que la cúbica rinde al 100 %, seguimos en contacto. 73.?"
