BIG SIGNAL 2BS-3B
Antenna Directional 3 Bands 2 element 20/15/10 m
In BIG SIGNAL we have the famous multi-band Cubical Quad antenna with 2 elements and 3 bands. ¡The real queen of the DX!
But this is a model that currently breaks all the schemes in this type of antennas, from the optimization of electrical design with state-of-the-art software to the mechanical part, innovating and using the latest advances in materials guaranteeing extreme durability.
Why choose the 2BS-3B antenna versus a multiband Yagi antenna?
· 3 bands of full wavelength, reaching maximum efficiency in TX / RX.
· Very low noise because it's a closed antenna, which will allow you to attenuate the QRM and improve the reception of weak signals in DX.
· Very low radiation angle even installed at low height, essential for the DX.
· Extraordinary lateral rejection and front / back, providing high directivity and reducing noise in the rejection directions.
· Comparable performance as multiband Yagis of 3-4 el. full-size. Much bigger.
· Just over 4 meters of turning radius, ideal for installations with limited space.
· Super heavy-duty construction for extreme durability, forget about maintenance.
· Super light weight compared to aluminum Yagis with similar characteristics.
The best directional antenna option for the DX in urban environments, in times when noise in cities is increasingly high, a closed antenna is the definitive solution to improve the reception of weak signals in DX.
