BIG SIGNAL is proud to introduce the latest generation in design and development of cubical antennas for the VHF band / 144 MHz. Our BIG SIGNAL 12BS-2 antenna is the largest and highest-gain model available in VHF, delivering exceptional performance for VHF DXing.

Advantages of choosing a cubical quad antenna in VHF over a traditional Yagi:

- Full-wavelength elements, ensuring maximum performance and efficiency.
- More gain in less boom length compared to a Yagi of the same size.
- Significant noise reduction. Being a closed antenna allows you to reduce QRN and urban noise, significantly improving the reception quality of extremely weak signals in the band.
- Less affected by polarization cross or change compared to a traditional Yagi. This translates to less QSB, fading, or signal loss when receiving signals with different polarizations, making it ideal for satellite or point-to-point communications.
- High selectivity with excellent sidelobe and backlobe suppression, further reducing unwanted noise in the rejection directions.
- Easy and fast installation with preassembled elements and tool-free assembly.
