BIG SIGNAL 6BS-6
6-Element Cubical Quad for High-Performance DX on 50 MHz
6-Element Cubical Quad for High-Performance DX on 50 MHz
The BIG SIGNAL 6BS-6 is a 6-element single-band Cubical Quad antenna developed for operators looking for a high level of performance on the 50 MHz / 6-meter band.
Its combination of full-wave elements, high directivity, and closed-loop design makes it especially well suited for DX and weak-signal reception on one of the most exciting and demanding amateur radio bands.

Key Features
• 6 Full-Wave Elements
Unlike the half-wave elements commonly used in many Yagi antennas, the 6BS-6 uses full-wave loops specifically optimized for the 50 MHz band.

• Designed for Serious DX
Its six elements provide a combination of gain and directivity aimed at long-distance communications, where every dB and every improvement in signal-to-noise ratio can make a real difference.

• Weak-Signal Reception
Its closed-loop configuration can provide a favorable signal-to-noise ratio against certain types of electrical interference, an especially useful characteristic when searching for DX signals close to the reception threshold.

• Excellent Directivity
Its radiation pattern concentrates energy in the desired direction while providing significant rejection of signals arriving from other directions, helping improve reception under difficult RF conditions.

• Greater Stability with Polarization Changes
Cubical Quad geometry can provide favorable behavior under certain changes in received-signal polarization, helping reduce the effects of QSB and fading during DX contacts.

Designed to Make the Most of 6 Meters
The 50 MHz band can produce extraordinary propagation openings, but it can also deliver extremely weak signals and very short operating windows. Under these conditions, gain, directivity, and a strong signal-to-noise ratio become especially important.
The BIG SIGNAL 6BS-6 is designed precisely for this type of operation: stations that want to move beyond a basic antenna and step up to a high-performance directional system for DX and weak-signal work on 6 meters.
BIG SIGNAL 6BS-6 Advantages
• 6 full-wave elements optimized for 50 MHz.
• High gain and directivity for DX.
• Excellent performance for weak-signal operation.
• Closed-loop design with a favorable signal-to-noise ratio under certain conditions.
• Good rejection of side and rear signals.
• Rugged construction for permanent outdoor installations.
Six Elements to Go Farther on the Magic Band.
The BIG SIGNAL 6BS-6 is designed for operators who want to seriously explore the possibilities of 50 MHz: six full-wave elements, high directivity, and a configuration focused on achieving maximum performance in DX and weak-signal reception.

The purchase of the products is always made on request. We manufacture all products, so manufacturing times can be added. That is why the final price of the purchase, as the final price of the shipping costs will be confirmed in an email sent afterwards.
The form of payment will be made once the email is received, so at all times you can cancel the order informing us of the process.
The antenna is more than A BEAST.
I have crossed North America to Mexico to caribean islands as Pj4, FG8 and WP4. Some North Africa countries then to FK8, VK8, YB, 9M2, XV1A and the JA mostly every day.
ALL THAT WITH 75 WATTS ONLY.
The performance of the antenna has surprised me a lot.
