At BIG SIGNAL we have the latest generation in the design and development of cubic antennas for the 14 MHz / 20 m band.
Why choose a BIG SIGNAL 2BS-20 Quad antenna versus a traditional Yagui?
· Full wavelength elements: reaching maximum performance and efficiency. · Very low noise: being a closed quad antenna with horizontal polarization, it will allow you to attenuate QRN and urban noise, improving the reception quality of weak signals in the band. · More gain in less boom length than a traditional Yagi of the same size. · Very low radiation angle even installed at a low height: this allows us to make fewer jumps until we reach the DX, which results in a stronger signal on the other side. For this reason, it is known that quad antennas are the first to open and the last to close propagation. · High selectivity: Extraordinary side and back lobe suppression, further reducing unwanted noise in the rejection directions. · Less crossover or polarization influence: This translates into less QSB and signal stability when receiving DX stations. · Just over 4 meters of turning radius. Ideal in small spaces, no antenna is capable of offering this performance and turning in such a small space. · Super robust construction for extreme durability, forget about maintenance. · Very light weight compared to aluminum Yagis with similar characteristics. · Simple assembly and Plug&Play: it does not require any adjustment once installed.
Because a Quad antenna is the best directional antenna for DX due to its performance and benefits. In addition, in times where the noise in cities is increasingly high, a cubical quad antenna is the definitive solution for the practice of DX with the maximum performance guaranteed.
