At BIG SIGNAL, we proudly introduce the latest generation of cubical antennas for the VHF band at 144 MHz. Presenting the BIG SIGNAL 10BS-2, a 10-element masterpiece.
Why choose a cubical quad antenna in VHF over a traditional Yagi?
- Full Wavelength Antenna in 2 meters, ensuring maximum performance and efficiency.
- More gain in a shorter boom length compared to a Yagi of the same size.
- Minimal noise. Being a closed antenna allows for a reduction in QRN and urban noise, significantly enhancing the reception quality of extremely weak signals within the band.
- Less influenced by polarization changes than a Yagi, resulting in reduced QSB, fading, or signal loss when receiving signals with different polarization. Ideal for TR, SAT, or EME communications.
- High selectivity. Outstanding sidelobe and backlobe suppression further diminish unwanted noise in the rejection directions.
- Quick and easy installation, with preassembled elements and tool-free assembly.
The top directional antenna choice for 144 MHz in urban environments. In a world where city noise continues to rise, a cubical antenna is the ultimate solution for DXing with guaranteed maximum performance.
