BIG SIGNAL 8BS-2
8-Element Cubical Quad Antenna for High-Performance 144 MHz Operation
The BIG SIGNAL 8BS-2 is an 8-element directional Cubical Quad antenna developed for operators looking to take gain, directivity, and weak-signal reception to the next level on the 144 MHz / 2-meter band.
Its design uses full-wave loop elements and is especially suited to terrestrial DX, SSB, digital modes, and weak-signal communications, where every dB and a good signal-to-noise ratio can make the difference.
Band: 144 MHz / 2 m
Type: Single-band directional Cubical Quad
Elements: 8 full-wave elements
Design: Long-spacing configuration
Applications: DX / weak signals / SSB / digital modes
Assembly: Pre-assembled elements

Why Choose the BIG SIGNAL 8BS-2?
• 8 Full-Wave Loop Elements
Unlike conventional Yagi configurations based on elements approximately half a wavelength long, the 8BS-2 uses full-wave closed-loop elements, one of the fundamental characteristics of the Cubical Quad design.

• High Gain with an Optimized Structure
Its 8-element long-spacing configuration is designed to provide high directional performance, making it an especially interesting alternative to Yagi antennas offering comparable performance.

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

• High Directivity and Selectivity
Its radiation pattern is designed to concentrate the signal in the desired direction while providing good suppression of signals arriving from unwanted directions, helping improve reception in demanding RF environments.

• Good Performance with Polarization Variations
The Cubical Quad geometry can reduce the impact of certain variations in the polarization of received signals, contributing to greater reception stability under changing propagation conditions.

Mi idea era poner una antena para VHF y UHF para iniciarme un poco en estas bandas, no queria unas antenas muy grandes y aparatosas, pero si queria que tuviesen un gran rendimiento, por lo menos el mejor posible, en un tamaño comedido. Despues de dar muchas vueltas, buscar información y comentarios, me he decidido por una 8BS-2 y 12BS-70.
Las antenas estan mecanicamente perfectas, muy sencillas de montar y seguro que daran buenos dias de entretenimiento y DXs.
Nos escuchamos desde IN73DL.
Dear Radio Amateurs.
I am happy for the decision to buy the 8 ele. Quad Antenna for the 2m Band.
Now I am able to hear stations, that I have never heard before. You can try it. Iam sure, that this is the first 8ele. Quad antenna, now working in Carinthia-Austria.
With the very best regards
