BIG SIGNAL 4BS-10
High-Performance Quad Antenna for 28 MHz / 10 meters
At BIG SIGNAL, we specialize in the latest-generation design and development of full-wave cubical quad antennas—and the 4BS-10 is our flagship model for the 10-meter band, built for serious operators who demand top-tier performance.
Why choose the BIG SIGNAL 4BS-10 over a traditional Yagi?
• Full-wavelength elements
Delivers maximum efficiency in both TX and RX, far superior to half-wave element Yagis.
• More gain with less boom
Achieve greater performance in a shorter boom than traditional designs—perfect for limited tower space.
• Extremely low noise reception
Its closed-loop structure dramatically reduces urban QRM, allowing you to hear the weakest DX signals even in noisy environments.
• Optimized with next-gen simulation software
Designed using advanced electromagnetic modeling, ensuring precision pattern control and best-in-class electrical performance.
• Outstanding F/R and F/B ratios
Excellent signal suppression from the sides and rear—focus your signal and reduce QRM.
• Low radiation angle, even at modest heights
Perfect for long-haul DX, even without a high tower.
• Comparable to a 6-element full-size Yagi
Delivers similar or better gain and performance—with less weight and wind load.
• Heavy-duty build quality
Constructed with premium-grade materials for maximum durability in harsh conditions.
Proven in contest-winning stations
The BIG SIGNAL 4BS-10 isn’t just theory—it’s been part of record-breaking contest operations on 10 meters, proving its power and performance on the air.
BIG SIGNAL 4BS-10
Trusted by some of the most powerful and competitive 10-meter stations worldwide.
If you're serious about dominating 28 MHz, this is the antenna that delivers the edge.

I like cubical quad antennas and have made several. I installed a 4BS-10 on a homemade tilt tower at 52' and am very impressed with its performance on receive, as well as transmit. To camper it with a yagi is being unfair to the yagi. The construction of the antenna is strong enough, avoiding being too heavy. Great product!

Soy poseedor de una y solo puedo decir elogios sobre esta antena. Fácil montaje, liviana y muy potente en rx/tx. Las estaciones que contacto con ella dicen que sus señales son muy estables o apenas Qsb.
Le doy un 10/10. Gracias Fullwave man!!!
