BIG SIGNAL have the latest generation in design and development of Quad antennas for 14 MHz / 20 m.

Why choose the 3BS-20 antenna versus a traditional Yagui?

· Elements of full wavelength, reaching maximum efficiency in TX / RX.
· Optimized design with last generation software.
· More gain in less boom length than a traditional Yagi.
· Very low noise, which will allow you to improve the reception of low signals in urban environments.
· Extraordinary F/R and F/B.
· Very low radiation angle even at low height, essential for working DX.
· Comparable performance with a 5 element full-size Yagui antenna.
· Very small turning radius, ideal for small spaces.
· Heavy-Duty construction with high quality materials for extreme durability.

The best directional antenna option for the DX in urban environments, in times when QRM in cities is increasingly high, a closed antenna is the definitive solution to improve DX reception.
