Get ready to take your 10-meter band DX communications to the next level with the BIG SIGNAL 2BS-10 Cubical Quad Antenna — a true masterpiece of design and performance!
Why is the BIG SIGNAL 2BS-10 your #1 choice for a directional antenna?
· Outstanding DX performance with just 2 elements:
Despite its compact size, this 2-element cubical quad is a powerhouse. Why settle for less when you can enjoy maximum DX performance?
· Unmatched advantages:
· More gain in less space:
Unlike traditional 1/2-wave Yagi antennas, the elements of a cubical quad are full wavelength, allowing this 2-element antenna to rival the gain of 3 to 4 element full-size Yagis on the same band.
· Quiet, clear reception:
Thanks to its closed-loop design, the antenna significantly reduces urban and QRN noise, delivering crystal-clear reception — even when signals are weak.
· Very low radiation angle:
Even when mounted at lower heights, the 2BS-10 provides an impressively low radiation angle, helping your signals travel farther and stronger. Cubical quads are known for being the first to open and the last to close during band openings.
· Stable signal performance:
Enjoy reduced QSB and more stable DX reception. With the 2BS-10, your long-distance contacts are more consistent and reliable than ever before.
· High selectivity:
Excellent side and rear lobe suppression drastically reduces unwanted noise from off-axis directions.
· Compact and rugged:
With a turning radius of just over 2 meters (around 7 feet), this directional antenna fits virtually anywhere without compromising performance. Its robust construction ensures long-lasting durability.
The perfect choice for noisy urban environments:
In a world where city noise continues to rise, the BIG SIGNAL 2BS-10 Cubical Quad stands out as the ultimate solution for serious DXers, delivering unbeatable performance.

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.
este año despues del paron de propagacion con esta antena de dos elementos he gozado como un chico pequeño manejable pequeña en tamaño pero resultona en su cometido pedro ea2jc
