At BIG SIGNAL we have the latest generation in the design and development of cubic antennas for the 28 MHz / 10 m band.

Why choose a BIG SIGNAL 2BS-10 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 2 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.

    I bought a Two-Element Quad for 10m last year from Big Signal Antennas and was just this month (06/24) able to set it up.
    The building was quite easy, when it's finally understood that the hose clamps needed to be in a specific position to hold the spiders.
    Maybe that could be pointed out stronger in the manual.
    And maybe it's better that people know that the antenna is tuned for the 10m SSB/ Phone section, not for the CW/Digimode area.

    But the result is just awesome!
    I set everything up, went to the radio, and really thought i've forgot to plug in the coax.

    There was absolutely no noise- ZERO! QRM.
    I couldn't believe my eyes, because on my verticals or even on a horizontal dipole I always had some static and QRM around S 2-3.
    But the static really was at S0!
    I have always read that quads are low noise antennas, but now I understand.

    The performance is great. In just a couple of days working with the antenna i just reached five new DXCC in the pacific, and Australia isn't a rare bird anymore on FT8, now it is a rather common sight.

    Thank you very much for constructing so well working, easy to set up antennas.
